830 302 conformant loader) will now work correctly in most cases (they
831 are still subject to the constraints that exist for all code running

992==========================
993
994*Release date: 04-Dec-2008*
995
996Core and Builtins
997-----------------
998
999- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1000 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1001 instead of throwing a MemoryError.
1002
1003- Issue #4367: Python would segfault during compiling when the unicodedata
1004 module couldn't be imported and \N escapes were present.
1005
1006- Issue #4348: Some bytearray methods returned that didn't cause any change to
1007 the bytearray, returned the same bytearray instead of a copy.
1008
1009- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1010
1011- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1012
1013- Issue #4048: The parser module now correctly validates relative imports.
1014
1015- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1016 exec statement.
1017
1018- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1019 method does not return iterators for the 4th and 5th items.
1020
1021- Issue #4209: Enabling unicode_literals and the print_function in the same
1022 __future__ import didn't work.
1023
1024- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1025 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1026 really executed because I cannot move to such directory on win2k)
1027
1028- Issue #4069: When set.remove(element) is used with a set element, the element
1029 is temporarily replaced with an equivalent frozenset. But the eventual
1030 KeyError would always report the empty frozenset([]) as the missing key. Now
1031 it correctly refers to the initial element.
1032
1033- Fixed C99 style comments in several files. Python is now C89 compatible
1034 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001181- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1182
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001183- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1184 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1185 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1186 ``printf`` function, whereas PyString_FromFormat has an independent
1187 implementation and uses "%zd" on all platforms for size_t values.
1188 This makes a difference on win64, where ``printf`` needs "%Id" to display
1189 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001206 was correctly parsed but parsing of subsequent arguments failed.
1207
Vinay Sajip35e3b032008-09-01 14:33:59 +00001208- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001209 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1210 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1211 when given a tuple of classes as second argument, were looking up
1212 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1213 type object.

Benjamin Peterson37346b22008-08-23 20:27:43 +00001305Extension Modules
1306-----------------
1307
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001308- Issue #2975: When compiling several extension modules with Visual Studio 2008
1309 from the same python interpreter, some environment variables would grow
1310 without limit.
1311
Benjamin Peterson37346b22008-08-23 20:27:43 +00001312- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1313 exploitation of poor argument checking.
1314
Gerhard Häringef2276b2008-09-12 13:54:06 +00001315- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
1316
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00001317- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
1318 remaining ones have "pysqlite_" prefix.
1319
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001320- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00001327- Issue #3781: Add test.test_support.check_warnings() as a convenience
1328 wrapper for warnings.catch_warnings() that makes it easier to check
1329 that expected warning messages are being reported.
1330
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001331- Issue #3796: Some tests functions were not enabled in test_float.
1332

1339
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001340- Issue #2271: Set SecureCustomProperties so that installation will properly

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001349What's New in Python 2.6 beta 3?
1350================================
1351
Barry Warsaw07a4a382008-08-21 01:15:08 +00001352*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001353
1354Core and Builtins
1355-----------------
1356
Guido van Rossumf8402962008-08-20 15:01:50 +00001357- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1358 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1359 extensions do not automatically benefit from the class attribute
1360 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1361 to their tp_flags field if they care. This is a backwards
1362 compatibility feature; in 3.0, all types will use the cache by
1363 default.
1364
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001365- Keyword arguments can now follow starred arguments. (``f(a, *args,
1366 keyword=23)`` is now valid syntax.)
1367
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001368- ctypes function pointers that are COM methods have a boolean True
1369 value again.
1370
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001371- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1372 by denying s# to parse objects that have a releasebuffer procedure,
1373 and introducing s*.
1374
Georg Brandl1e13ea92008-08-11 09:07:59 +00001375- Issue #3537: Fix an assertion failure when an empty but presized dict
1376 object was stored in the freelist.
1377
Mark Dickinsonb6467572008-08-04 21:30:09 +00001378- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1379 ValueError consistently across platforms.
1380
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001381- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1382 (64bit Unix, for example), unichr() would truncate its argument and return
1383 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1384
Neal Norwitze7d8be82008-07-31 17:17:14 +00001385- Apply security patches from Apple.
1386
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001387- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1388 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1389
Antoine Pitrou92f82162008-07-25 22:22:08 +00001390- Issue #1819: function calls with several named parameters are now on
1391 average 35% faster (as measured by pybench).
1392
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001393- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1394 the python debugger steps into a class statement: the free variables (local
1395 variables defined in an outer scope) would be deleted from the outer scope.
1396
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001397- Issue #2620: Overflow checking when allocating or reallocating memory
1398 was not always being done properly in some python types and extension
1399 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1400 all been updated to perform better checks and places in the code that
1401 would previously leak memory on the error path when such an allocation
1402 failed have been fixed.
1403
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001404Library
1405-------
1406
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001407- Issue #3612: Added some missing basic types in ctypes.wintypes.
1408
Benjamin Petersone977ad42008-08-20 01:42:01 +00001409- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1410 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1411
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001412- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1413 version reported by these tools does not necessarily follow the python
1414 version numbering scheme, so the module is less strict when parsing it.
1415
Nick Coghlanf70385a2008-08-18 12:42:46 +00001416- Issue #2235: Added Py3k warnings for types which will become unhashable
1417 under the stricter __hash__ inheritance rules in 3.0. Several types
1418 which did not meet the rules for hash invariants and were already
1419 unhashable in 3.0 have now been explicitly flagged as unhashable in
1420 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1421 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1422
Brett Cannon88f801d2008-08-18 00:46:22 +00001423- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1424 imported into the module but exposed as part of the module's API.
1425
Brett Cannon7b96f072008-08-18 00:41:11 +00001426- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1427
Brett Cannon46225e72008-08-18 00:36:52 +00001428- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1429
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001430- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1431
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001432- Issue #3575: Incremental decoder's decode function now takes bytearray
1433 by using 's*' instead of 't#'.
1434
Jesus Cea585ad8a2009-07-02 15:37:21 +00001435- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001436 fails unicode conversion on 2nd parameter. (windows only)
1437
Facundo Batista94f243a2008-08-17 03:38:39 +00001438- Issue 2464. urllib2 now supports a malformation in the URL received
1439 in a redirect.
1440
Brett Cannonabe423e2008-08-16 21:47:07 +00001441- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001442 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001443
Facundo Batistaeb90b782008-08-16 14:44:07 +00001444- Issue #2776: fixed small issue when handling an URL with double slash
1445 after a 302 response in the case of not going through a proxy.
1446
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001447- Issue #2676: in the email package, content-type parsing was hanging on
1448 pathological input because of quadratic or exponential behaviour of a
1449 regular expression.
1450
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001451- Issue #3476: binary buffered reading through the new "io" library is now
1452 thread-safe.
1453
Brett Cannonbf3157b2008-08-14 05:00:03 +00001454- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1455 since mimetools itself is deprecated. Because modules are cached, all
1456 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1457
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001458- Issue #3134: shutil referenced undefined WindowsError symbol.
1459
Robert Schuppenies14646332008-08-10 11:01:53 +00001460- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1461 menu entries were not deleted.
1462
Brett Cannon83e81842008-08-09 23:30:55 +00001463- Copied the implementation of reduce() to _functools.reduce() to have a
1464 version that did not raise a DeprecationWarning under -3.
1465
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001466- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1467 a MemoryError rather than silently stop the iteration.
1468
Guido van Rossum59ce9012008-08-09 14:55:34 +00001469- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1470 to _sre.compile() will now be rejected. This should not affect anybody
1471 since the re.compile() function never generates invalid re-bytecode.
1472
Skip Montanaroa032bf42008-08-08 22:52:51 +00001473- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1474 upon first access it can be automatically initialized from the csv file if
1475 it wasn't initialized during instantiation.
1476
Brett Cannon3aa2a492008-08-06 22:28:09 +00001477- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1478 the reload() built-in has been removed.
1479
Brett Cannon7e30b672008-08-04 21:52:25 +00001480- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001481 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001482 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1483 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1484 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1485 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1486 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001487
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001488- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1489 raised an AttributeError.
1490
Benjamin Peterson01a24322008-07-28 23:35:27 +00001491- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001492 asking for a specific length. This problem only affected files opened
1493 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001494
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001495- Issue #3449: Update decimal module to use most recent specification
1496 (v. 1.68) and tests (v. 2.58) from IBM.
1497
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001498- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1499

1504
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001505- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1506
1507- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1508 invalid arguments.
1509
1510- Issue #3302: Fix several crashes when calling locale's gettext functions
1511 with None arguments.
1512
1513- Issue #3389: Allow resolving dotted names for handlers in logging
1514 configuration files.
1515
1516- Deprecate the sunaudio module for removal in Python 3.0.
1517
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001518- Issue #3394: zipfile.writestr sets external attributes when passed a
1519 file name rather than a ZipInfo instance, so files are extracted with
1520 mode 0600 rather than 000 under Unix.
1521
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001522- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1523 argument in python 2.5, this broke code that subclassed Popen to include its
1524 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1532-------------
1533
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001534- Issue #2235: the C API function PyObject_HashNotImplemented and its
1535 interaction with the tp_hash slot (added in 2.6b2) are now documented
1536
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001537- Issue #643841: The language reference now provides more detailed
1538 coverage of the lookup process for special methods. The disclaimers
1539 regarding lack of coverage of new-style classes have also been
1540 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001543What's New in Python 2.6 beta 2?
1544================================
1545
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001546*Release date: 17-Jul-2008*
1547
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001548Core and Builtins
1549-----------------
1550
Georg Brandl3e483f62008-07-16 22:57:41 +00001551- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1552 its methods now allow for items objects that can be converted to
1553 an integer using operator.index().
1554
Mark Dickinson64b7e502008-07-16 09:40:03 +00001555- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1556 produced a ValueError instead of giving the correct float.
1557
Eric Smitha5fa5a22008-07-16 00:11:49 +00001558- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1559 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1560
Mark Dickinson7103aa42008-07-15 19:08:33 +00001561- Issue #3008: the float type has a new instance method 'float.hex'
1562 and a new class method 'float.fromhex' to convert floating-point
1563 numbers to and from hexadecimal strings, respectively.
1564
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001565- Issue #2235: __hash__ is once again inherited by default. To allow
1566 collections.Hashable to remain meaningful in the presence of the
1567 default hash implementation (object.__hash__), it is now possible
1568 to explicit block inheritance of hash by setting __hash__=None at
1569 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1570 level.
1571
Nick Coghlanb028f502008-07-13 14:52:36 +00001572- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1573 the parent module cannot be found while performing an absolute import.
1574 This means that an incorrectly defined __package__ attribute will
1575 now only prevent relative imports in that module rather than causing
1576 all imports from that module to fail.
1577
Nick Coghlan14ff9942008-07-08 14:21:42 +00001578- Issue #2517: Allow unicode messages in Exceptions again by correctly
1579 bypassing the instance dictionary when looking up __unicode__ on
1580 new-style classes.
1581
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001582- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1583 set to a custom object whose write() method happens to install
1584 another file in sys.stdout.
1585
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001586- Issue #3088: Corrected a race condition in classes derived from
1587 threading.local: the first member set by a thread could be saved in
1588 another thread's dictionary.
1589
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001590- Issue #3004: Minor change to slice.indices(): the start and stop
1591 arguments are now treated identically, making the behaviour easier
1592 to describe and understand. For example, slice(None, -10,
1593 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1594 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1595 10, -1).
1596
Georg Brandl278fc502008-07-19 12:46:12 +00001597- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Issue #1631171: Re-implement the 'warnings' module in C (the
2112 original Python code has been kept as backup). This will allow for
2113 using the 'warning's machinery in such places as the parser where
2114 use of pure Python code is not possible. Both the ``showarning()``
2115 and ``formatwarning()`` gain an optional 'line' argument which is
2116 not called by default for backwards-compatibility reasons. Setting
2117 ``warnings.showwarning()`` to an implementation that lacks support
2118 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002181- Issue #2550: The approach used by client/server code for obtaining
2182 ports to listen on in network-oriented tests has been refined in an
2183 effort to facilitate running multiple instances of the entire
2184 regression test suite in parallel without issue.
2185 test_support.bind_port() has been fixed such that it will always
2186 return a unique port -- which wasn't always the case with the
2187 previous implementation, especially if socket options had been set
2188 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2189 new implementation of bind_port() will actually raise an exception
2190 if it is passed an AF_INET/SOCK_STREAM socket with either the
2191 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2192 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2193 the socket it's been passed. This currently only applies to
2194 Windows. This option prevents any other sockets from binding to the
2195 host/port we've bound to, thus removing the possibility of the
2196 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2197 when a second SOCK_STREAM socket binds and accepts to a host/port
2198 that's already been bound by another socket. The optional preferred
2199 port parameter to bind_port() has been removed. Under no
2200 circumstances should tests be hard coding ports!
2201
2202 test_support.find_unused_port() has also been introduced, which will
2203 pass a temporary socket object to bind_port() in order to obtain an
2204 unused port. The temporary socket object is then closed and
2205 deleted, and the port is returned. This method should only be used
2206 for obtaining an unused port in order to pass to an external program
2207 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2208 a parameter to a server-oriented class that doesn't give you direct
2209 access to the underlying socket used.
2210
2211 Finally, test_support.HOST has been introduced, which should be used
2212 for the host argument of any relevant socket calls (i.e. bind and
2213 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002214
2215 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002216 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002217 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2218 test_asynchat and test_socket_ssl.
2219
Georg Brandl3ee81df2008-05-17 18:14:43 +00002220 It is now possible for multiple instances of the regression test
2221 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00002425- The bundled libffi copy is now in sync with the recently released
2426 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002427 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2428 files are used. On all linux systems the --with-system-ffi
2429 configure option defaults to "yes".

2487Core and builtins
2488-----------------
2489
Fred Drakea8ee94b2008-03-01 02:45:07 +00002490- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002491 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002492
Georg Brandlad61bc82008-02-23 15:11:18 +00002493- Issue #2067: file.__exit__() now calls subclasses' close() method.
2494
2495- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002496
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002497- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002498 issue 215555 for a discussion.
2499
Eric Smitha73fbe72008-02-23 03:09:44 +00002500- Added the future_builtins module, which contains hex() and oct().
2501 These are the PEP 3127 version of these functions, designed to be
2502 compatible with the hex() and oct() builtins from Python 3.0. They
2503 differ slightly in their output formats from the existing, unchanged
2504 Python 2.6 builtins. The expected usage of the future_builtins
2505 module is:
2506 from future_builtins import hex, oct
2507
Eric Smith7ef40bf2008-02-20 23:34:22 +00002508- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2509 exponents for exponents with absolute value < 100. Follows C99
2510 standard. This is a change on Windows, which would use 3 digits.
2511 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2512 so that any alterations it does to the resulting string will be
2513 available in stringlib/formatter.h (for float.__format__).
2514
Eric Smith5a3c1352008-02-19 13:21:56 +00002515- Implemented PEP 3101, Advanced String Formatting. This adds a new
2516 builtin format(); a format() method for str and unicode; a
2517 __format__() method to object, str, unicode, int, long, float, and
2518 datetime; the class string.Formatter; and the C API
2519 PyObject_Format().
2520
Georg Brandl3ee81df2008-05-17 18:14:43 +00002521- Fixed several potential crashes, all caused by specially crafted
2522 __del__ methods exploiting objects in temporarily inconsistent
2523 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002524
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002525- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002526 prevent a possible crash: an Abstract Base Class would try to access
2527 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002528
Georg Brandl3ee81df2008-05-17 18:14:43 +00002529- Fixed repr() and str() of complex numbers with infinity or nan as
2530 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002532- Clear all free lists during a gc.collect() of the highest generation
2533 in order to allow pymalloc to free more arenas. Python may give back
2534 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002535
Georg Brandl3ee81df2008-05-17 18:14:43 +00002536- Issue #2045: Fix an infinite recursion triggered when printing a
2537 subclass of collections.defaultdict, if its default_factory is set
2538 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002539
Christian Heimesf75dbef2008-02-08 00:11:31 +00002540- Fixed a minor memory leak in dictobject.c. The content of the free
2541 list was not freed on interpreter shutdown.
2542
Georg Brandl3ee81df2008-05-17 18:14:43 +00002543- Limit free list of method and builtin function objects to 256
2544 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002545
Georg Brandl3ee81df2008-05-17 18:14:43 +00002546- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2547 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002548 to compact the internal free lists of pre-allocted ints and floats.
2549
Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2551 calls. Python expected the return type int but the fork familie
2552 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002553
Georg Brandl3ee81df2008-05-17 18:14:43 +00002554- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2555 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002556
Georg Brandl3ee81df2008-05-17 18:14:43 +00002557- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2558 with the collections.Sequence API.

2564 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002565
Georg Brandl3ee81df2008-05-17 18:14:43 +00002566- Patch #1473257: generator objects gain a gi_code attribute. This is
2567 the same object as the func_code attribute of the function that
2568 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002569
Georg Brandl3ee81df2008-05-17 18:14:43 +00002570- Issue #1920: "while 0" statements were completely removed by the
2571 compiler, even in the presence of an "else" clause, which is
2572 supposed to be run when the condition is false. Now the compiler
2573 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002574
Guido van Rossumeead05f2008-01-24 18:21:02 +00002575- A few crashers fixed: weakref_in_del.py (issue #1377858);
2576 loosing_dict_ref.py (issue #1303614, test67.py);
2577 borrowed_ref_[34].py (not in tracker).
2578
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002579- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002580 suppressed while an extension is loaded by calling SetErrorMode in
2581 dynload_win.c. The error is still reported properly.
2582
Georg Brandl3ee81df2008-05-17 18:14:43 +00002583- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002584 several extension methods and modules do not work without unicode
2585 support.
2586
Georg Brandl26543b12008-01-21 18:36:51 +00002587- Issue #1882: when compiling code from a string, encoding cookies in the
2588 second line of code were not always recognized correctly.
2589
Georg Brandl14404b62008-01-19 19:27:05 +00002590- Issue #1679: "0x" was taken as a valid integer literal.
2591
Georg Brandl6caad7d2008-01-26 14:19:22 +00002592- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002593 added.
2594
Christian Heimesc94e2b52008-01-14 04:13:37 +00002595- sys.float_info / PyFloat_GetInfo: The floating point information
2596 object was converted from a dict to a specialized structseq object.
2597
Georg Brandl3ee81df2008-05-17 18:14:43 +00002598- Patch #1816: Added sys.flags structseq. It exposes the status of
2599 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002600
Georg Brandl3ee81df2008-05-17 18:14:43 +00002601- Objects/structseq.c: Implemented new structseq representation. The

2603 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002604
Georg Brandl3ee81df2008-05-17 18:14:43 +00002605- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002627 and INF. float("nan"), float("inf") and float("-inf") now work on
2628 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002629
Georg Brandl3ee81df2008-05-17 18:14:43 +00002630- Compiler now generates simpler and faster code for dictionary
2631 literals. The oparg for BUILD_MAP now indicates an estimated
2632 dictionary size. There is a new opcode, STORE_MAP, for adding
2633 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002662- Patch #1739468: Directories and zipfiles containing a __main__.py
2663 file can now be directly executed by passing their name to the
2664 interpreter. The directory/zipfile is automatically inserted as the
2665 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002667- Issue #1265: Fix a problem with sys.settrace, if the tracing
2668 function uses a generator expression when at the same time the
2669 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002670
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002671- sets and frozensets now have an isdisjoint() method.
2672

2674
Neal Norwitz44f326e2007-10-05 05:29:17 +00002675- Fix warnings found by the new version of the Coverity checker.
2676
Georg Brandl3ee81df2008-05-17 18:14:43 +00002677- The enumerate() builtin function is no longer bounded to sequences
2678 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2679 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002680
Georg Brandl3ee81df2008-05-17 18:14:43 +00002681- Issue #1686386: Tuple's tp_repr did not take into account the
2682 possibility of having a self-referential tuple, which is possible
2683 from C code. Nor did object's tp_str consider that a type's tp_str
2684 could do something that could lead to an inifinite recursion.
2685 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2686 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002687
Georg Brandl3ee81df2008-05-17 18:14:43 +00002688- Issue #1164: It was possible to trigger deadlock when using the
2689 'print' statement to write to a file since the GIL was not released
2690 as needed. Now PyObject_Print() does the right thing along with
2691 various tp_print implementations of the built-in types and those in
2692 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002693
Georg Brandl3ee81df2008-05-17 18:14:43 +00002694- Issue #1147: Exceptions were directly allowing string exceptions in
2695 their throw() method even though string exceptions no longer
2696 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002697
Georg Brandl3ee81df2008-05-17 18:14:43 +00002698- Issue #1096: Prevent a segfault from getting the repr of a very
2699 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002700
Brett Cannon1e534b52007-09-07 04:18:30 +00002701- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002702 PyObject_Call() never calling back out to Python code to trigger
2703 recursion depth updates/checks. Required the creation of a static
2704 RuntimeError instance in case normalizing an exception put the
2705 recursion check value past its limit. Fixes crashers
2706 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002707
Georg Brandl3ee81df2008-05-17 18:14:43 +00002708- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002721- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002722 __*__ attributes. (Some already existed, e.g., __doc__ and
2723 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002724
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002725- Add -3 option to the interpreter to warn about features that are
2726 deprecated and will be changed/removed in Python 3.0.
2727
Georg Brandl2134e752007-05-21 20:34:16 +00002728- Patch #1686487: you can now pass any mapping after '**' in function
2729 calls.
2730
Collin Winter62903052007-05-18 23:11:24 +00002731- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002732 "except E as target:". This is to provide forwards compatibility
2733 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002734
Brett Cannon229cee22007-05-05 01:34:02 +00002735- Deprecate BaseException.message as per PEP 352.
2736
Georg Brandl3ee81df2008-05-17 18:14:43 +00002737- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002738 inherited from a builtin base.
2739
Vinay Sajip8549ce32007-05-06 17:53:37 +00002740- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002741 setting a plain string, ie don't expand to single letter identifiers.
2742
Raymond Hettinger13936692007-04-11 18:40:58 +00002743- Request #1191699: Slices can now be pickled.
2744
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002745- Request #1193128: str.translate() now allows a None argument for
2746 translations that only remove characters without re-mapping the
2747 remaining characters.
2748
Georg Brandl5cb76c12007-03-21 09:00:39 +00002749- Patch #1682205: a TypeError while unpacking an iterable is no longer
2750 masked by a generic one with the message "unpack non-sequence".
2751
Neal Norwitzaa754b72007-03-21 06:39:48 +00002752- Remove unused file Python/fmod.c.
2753
Guido van Rossum143b5642007-03-23 04:58:42 +00002754- Bug #1683368: The object.__init__() and object.__new__() methods are
2755 now stricter in rejecting excess arguments. The only time when
2756 either allows excess arguments is when it is not overridden and the
2757 other one is. For backwards compatibility, when both are
2758 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002759 warning later). Also, type.__init__() insists on the same signature
2760 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002761
Georg Brandl3ee81df2008-05-17 18:14:43 +00002762- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2763 object to complex using its __complex__() method before falling back
2764 to the __float__() method. Therefore, the functions in the cmath
2765 module now can operate on objects that define a __complex__()
2766 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002767
Georg Brandl3ee81df2008-05-17 18:14:43 +00002768- Patch #1623563: allow __class__ assignment for classes with
2769 __slots__. The old and the new class are still required to have the
2770 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002771
Georg Brandl3ee81df2008-05-17 18:14:43 +00002772- Patch #1642547: Fix an error/crash when encountering syntax errors

2776 ``object.__reduce_ex__()`` is called with an object that is faking
2777 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002778
Georg Brandl3ee81df2008-05-17 18:14:43 +00002779- Patch #1680015: Don't modify __slots__ tuple if it contains an

2783
Georg Brandl7b9c5552007-03-12 14:30:05 +00002784- Bug #1678647: write a newline after printing an exception in any
2785 case, even when converting the value to a string failed.
2786
Georg Brandl871f1bc2007-03-12 13:17:36 +00002787- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002788 its argument, if it exists. If not, it will work like before. This
2789 allows customizing the output of dir() in the presence of a
2790 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002791
Collin Winter276887b2007-03-12 16:11:39 +00002792- Patch #922167: Python no longer segfaults when faced with infinitely
2793 self-recursive reload() calls (as reported by bug #742342).
2794
Georg Brandl3ee81df2008-05-17 18:14:43 +00002795- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002798- Patch #1491866: change the complex() constructor to allow
2799 parthensized forms. This means complex(repr(x)) now works instead of
2800 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002801
Georg Brandlaa2321b2007-03-07 00:40:28 +00002802- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002803 makes the filenames the warning module prints much more sensible
2804 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002805
Georg Brandl49aafc92007-03-07 00:34:46 +00002806- Variant of patch #697613: don't exit the interpreter on a SystemExit
2807 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808 variable is given, but break into the interactive interpreter just
2809 like on other exceptions or normal program exit.

2815 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002816
Georg Brandl0fca97a2007-03-05 22:28:08 +00002817- Patch #1674228: when assigning a slice (old-style), check for the
2818 sq_ass_slice instead of the sq_slice slot.
2819
Georg Brandl3ee81df2008-05-17 18:14:43 +00002820- When printing an unraisable error, don't print exceptions. before
2821 the name. This duplicates the behavior whening normally printing
2822 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002823
Georg Brandl3ee81df2008-05-17 18:14:43 +00002824- Bug #1653736: Properly discard third argument to

2831 created a weakref on itself during a __del__ call for new-style
2832 classes (classic classes still have the bug).

2879
Armin Rigo7ccbca92006-10-04 12:17:45 +00002880- A number of places, including integer negation and absolute value,

3451 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003732- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3733 with RFC 3207 and forgets any knowledge obtained from the server not
3734 obtained from the TLS negotiation itself. Patch contributed by Bill
3735 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003736
Georg Brandl3ee81df2008-05-17 18:14:43 +00003737- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003738 that the SMTP.starttls() caller no longer needs to call ehlo()
3739 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003740 does not claim to support starttls. Adds the
3741 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3822 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3823 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00003825

Georg Brandl3ee81df2008-05-17 18:14:43 +00003840 time so that opening a database previously created with the DB_DUP
3841 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3842 opens. Specifically: dictionary assignment to a DB object will
3843 replace all values for a given key when the database allows
3844 duplicate values. DB users should use DB.put(k, v) when they want
3845 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003846

3852 characters with ASCII value less than 32. Also, it correctly quotes
3853 dots only if they occur on a single line, as opposed to the previous
3854 behavior of quoting dots if they are the second character of any
3855 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003856

4179
Georg Brandl3ee81df2008-05-17 18:14:43 +00004180- Unified naming convention for free lists and their limits. All free
4181 lists in Object/ are named ``free_list``, the counter ``numfree``

4183 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004184
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4186 to ``PyTuple_SetItem``, it can be used to populate a brand new

4199
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4201 of w# format code incorrectly truncated the length to an int, even
4202 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4203 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004204
Georg Brandl3ee81df2008-05-17 18:14:43 +00004205- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4223- Fix some leftovers from the conversion from int to Py_ssize_t
4224 (relevant to strings and sequences of more than 2**31 items).
4225
4226- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4227 outside of pystate.c and should not be necessary.
4228
Georg Brandl3ee81df2008-05-17 18:14:43 +00004229- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4230 absolute imports. In earlier versions they might have used relative
4231 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004232
Georg Brandl3ee81df2008-05-17 18:14:43 +00004233- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4234 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004235
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4244 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4245 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4246 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004247

Georg Brandl3ee81df2008-05-17 18:14:43 +00004261- Removed the macfs module. It had been deprecated since Python 2.5.
4262 This lead to the deprecation of macostools.touched() as it relied
4263 solely on macfs and was a no-op under OS X.
