983What's New in Python 2.6.1
984==========================
985
986*Release date: 04-Dec-2008*
987
988Core and Builtins
989-----------------
990
991- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
992 interpreter to abort ("Fatal Python error: Could not reset the stack!")
993 instead of throwing a MemoryError.
994
995- Issue #4367: Python would segfault during compiling when the unicodedata
996 module couldn't be imported and \N escapes were present.
997
998- Issue #4348: Some bytearray methods returned that didn't cause any change to
999 the bytearray, returned the same bytearray instead of a copy.
1000
1001- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1002
1003- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1004
1005- Issue #4048: The parser module now correctly validates relative imports.
1006
1007- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1008 exec statement.
1009
1010- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1011 method does not return iterators for the 4th and 5th items.
1012
1013- Issue #4209: Enabling unicode_literals and the print_function in the same
1014 __future__ import didn't work.
1015
1016- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1017 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1018 really executed because I cannot move to such directory on win2k)
1019
1020- Issue #4069: When set.remove(element) is used with a set element, the element
1021 is temporarily replaced with an equivalent frozenset. But the eventual
1022 KeyError would always report the empty frozenset([]) as the missing key. Now
1023 it correctly refers to the initial element.
1024
1025- Fixed C99 style comments in several files. Python is now C89 compatible
1026 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001173- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1174
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001175- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1176 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1177 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1178 ``printf`` function, whereas PyString_FromFormat has an independent
1179 implementation and uses "%zd" on all platforms for size_t values.
1180 This makes a difference on win64, where ``printf`` needs "%Id" to display
1181 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001183- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1187 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001191- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001198 was correctly parsed but parsing of subsequent arguments failed.
1199
Vinay Sajip35e3b032008-09-01 14:33:59 +00001200- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001201 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1202 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1203 when given a tuple of classes as second argument, were looking up
1204 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1205 type object.
1206
Neal Norwitz18aa3882008-08-24 05:04:52 +00001207- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001341What's New in Python 2.6 beta 3?
1342================================
1343
Barry Warsaw07a4a382008-08-21 01:15:08 +00001344*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001345
1346Core and Builtins
1347-----------------
1348
Guido van Rossumf8402962008-08-20 15:01:50 +00001349- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1350 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1351 extensions do not automatically benefit from the class attribute
1352 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1353 to their tp_flags field if they care. This is a backwards
1354 compatibility feature; in 3.0, all types will use the cache by
1355 default.
1356
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001357- Keyword arguments can now follow starred arguments. (``f(a, *args,
1358 keyword=23)`` is now valid syntax.)
1359
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001360- ctypes function pointers that are COM methods have a boolean True
1361 value again.
1362
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001363- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1364 by denying s# to parse objects that have a releasebuffer procedure,
1365 and introducing s*.
1366
Georg Brandl1e13ea92008-08-11 09:07:59 +00001367- Issue #3537: Fix an assertion failure when an empty but presized dict
1368 object was stored in the freelist.
1369
Mark Dickinsonb6467572008-08-04 21:30:09 +00001370- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1371 ValueError consistently across platforms.
1372
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001373- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1374 (64bit Unix, for example), unichr() would truncate its argument and return
1375 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1376
Neal Norwitze7d8be82008-07-31 17:17:14 +00001377- Apply security patches from Apple.
1378
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001379- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1380 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1381
Antoine Pitrou92f82162008-07-25 22:22:08 +00001382- Issue #1819: function calls with several named parameters are now on
1383 average 35% faster (as measured by pybench).
1384
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001385- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1386 the python debugger steps into a class statement: the free variables (local
1387 variables defined in an outer scope) would be deleted from the outer scope.
1388
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001389- Issue #2620: Overflow checking when allocating or reallocating memory
1390 was not always being done properly in some python types and extension
1391 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1392 all been updated to perform better checks and places in the code that
1393 would previously leak memory on the error path when such an allocation
1394 failed have been fixed.
1395
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001396Library
1397-------
1398
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001399- Issue #3612: Added some missing basic types in ctypes.wintypes.
1400
Benjamin Petersone977ad42008-08-20 01:42:01 +00001401- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1402 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1403
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001404- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1405 version reported by these tools does not necessarily follow the python
1406 version numbering scheme, so the module is less strict when parsing it.
1407
Nick Coghlanf70385a2008-08-18 12:42:46 +00001408- Issue #2235: Added Py3k warnings for types which will become unhashable
1409 under the stricter __hash__ inheritance rules in 3.0. Several types
1410 which did not meet the rules for hash invariants and were already
1411 unhashable in 3.0 have now been explicitly flagged as unhashable in
1412 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1413 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1414
Brett Cannon88f801d2008-08-18 00:46:22 +00001415- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1416 imported into the module but exposed as part of the module's API.
1417
Brett Cannon7b96f072008-08-18 00:41:11 +00001418- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1419
Brett Cannon46225e72008-08-18 00:36:52 +00001420- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1421
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001422- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1423
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001424- Issue #3575: Incremental decoder's decode function now takes bytearray
1425 by using 's*' instead of 't#'.
1426
Jesus Cea585ad8a2009-07-02 15:37:21 +00001427- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001428 fails unicode conversion on 2nd parameter. (windows only)
1429
Facundo Batista94f243a2008-08-17 03:38:39 +00001430- Issue 2464. urllib2 now supports a malformation in the URL received
1431 in a redirect.
1432
Brett Cannonabe423e2008-08-16 21:47:07 +00001433- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001434 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001435
Facundo Batistaeb90b782008-08-16 14:44:07 +00001436- Issue #2776: fixed small issue when handling an URL with double slash
1437 after a 302 response in the case of not going through a proxy.
1438
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001439- Issue #2676: in the email package, content-type parsing was hanging on
1440 pathological input because of quadratic or exponential behaviour of a
1441 regular expression.
1442
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001443- Issue #3476: binary buffered reading through the new "io" library is now
1444 thread-safe.
1445
Brett Cannonbf3157b2008-08-14 05:00:03 +00001446- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1447 since mimetools itself is deprecated. Because modules are cached, all
1448 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1449
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001450- Issue #3134: shutil referenced undefined WindowsError symbol.
1451
Robert Schuppenies14646332008-08-10 11:01:53 +00001452- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1453 menu entries were not deleted.
1454
Brett Cannon83e81842008-08-09 23:30:55 +00001455- Copied the implementation of reduce() to _functools.reduce() to have a
1456 version that did not raise a DeprecationWarning under -3.
1457
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001458- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1459 a MemoryError rather than silently stop the iteration.
1460
Guido van Rossum59ce9012008-08-09 14:55:34 +00001461- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1462 to _sre.compile() will now be rejected. This should not affect anybody
1463 since the re.compile() function never generates invalid re-bytecode.
1464
Skip Montanaroa032bf42008-08-08 22:52:51 +00001465- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1466 upon first access it can be automatically initialized from the csv file if
1467 it wasn't initialized during instantiation.
1468
Brett Cannon3aa2a492008-08-06 22:28:09 +00001469- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1470 the reload() built-in has been removed.
1471
Brett Cannon7e30b672008-08-04 21:52:25 +00001472- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001473 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1477 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1478 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001480- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1481 raised an AttributeError.
1482
Benjamin Peterson01a24322008-07-28 23:35:27 +00001483- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001484 asking for a specific length. This problem only affected files opened
1485 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001486
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001487- Issue #3449: Update decimal module to use most recent specification
1488 (v. 1.68) and tests (v. 2.58) from IBM.
1489
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001490- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

1498
1499- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1500 invalid arguments.
1501
1502- Issue #3302: Fix several crashes when calling locale's gettext functions
1503 with None arguments.

1505- Issue #3389: Allow resolving dotted names for handlers in logging
1506 configuration files.
1507
1508- Deprecate the sunaudio module for removal in Python 3.0.
1509
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001510- Issue #3394: zipfile.writestr sets external attributes when passed a
1511 file name rather than a ZipInfo instance, so files are extracted with
1512 mode 0600 rather than 000 under Unix.
1513
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001514- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1515 argument in python 2.5, this broke code that subclassed Popen to include its
1516 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001526- Issue #2235: the C API function PyObject_HashNotImplemented and its
1527 interaction with the tp_hash slot (added in 2.6b2) are now documented
1528
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001529- Issue #643841: The language reference now provides more detailed
1530 coverage of the lookup process for special methods. The disclaimers
1531 regarding lack of coverage of new-style classes have also been
1532 removed, since the coverage is now fairly reasonable.

1537
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001538*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001540Core and Builtins
1541-----------------
1542
Georg Brandl3e483f62008-07-16 22:57:41 +00001543- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1544 its methods now allow for items objects that can be converted to
1545 an integer using operator.index().
1546
Mark Dickinson64b7e502008-07-16 09:40:03 +00001547- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1548 produced a ValueError instead of giving the correct float.
1549
Eric Smitha5fa5a22008-07-16 00:11:49 +00001550- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1551 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1552
Mark Dickinson7103aa42008-07-15 19:08:33 +00001553- Issue #3008: the float type has a new instance method 'float.hex'
1554 and a new class method 'float.fromhex' to convert floating-point
1555 numbers to and from hexadecimal strings, respectively.
1556
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001557- Issue #2235: __hash__ is once again inherited by default. To allow
1558 collections.Hashable to remain meaningful in the presence of the
1559 default hash implementation (object.__hash__), it is now possible
1560 to explicit block inheritance of hash by setting __hash__=None at
1561 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1562 level.
1563
Nick Coghlanb028f502008-07-13 14:52:36 +00001564- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1565 the parent module cannot be found while performing an absolute import.
1566 This means that an incorrectly defined __package__ attribute will
1567 now only prevent relative imports in that module rather than causing
1568 all imports from that module to fail.
1569
Nick Coghlan14ff9942008-07-08 14:21:42 +00001570- Issue #2517: Allow unicode messages in Exceptions again by correctly
1571 bypassing the instance dictionary when looking up __unicode__ on
1572 new-style classes.
1573
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001574- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1575 set to a custom object whose write() method happens to install
1576 another file in sys.stdout.
1577
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001578- Issue #3088: Corrected a race condition in classes derived from

1580 another thread's dictionary.
1581
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001582- Issue #3004: Minor change to slice.indices(): the start and stop
1583 arguments are now treated identically, making the behaviour easier
1584 to describe and understand. For example, slice(None, -10,
1585 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1586 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1587 10, -1).
1588
Georg Brandl278fc502008-07-19 12:46:12 +00001589- Issue #3219: Calling a function with repeated keyword arguments,
1590 f(a=2, a=23), would not cause a syntax error. This was a regression
1591 from 2.4 caused by the switch to the new compiler.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002103- Issue #1631171: Re-implement the 'warnings' module in C (the
2104 original Python code has been kept as backup). This will allow for
2105 using the 'warning's machinery in such places as the parser where
2106 use of pure Python code is not possible. Both the ``showarning()``
2107 and ``formatwarning()`` gain an optional 'line' argument which is
2108 not called by default for backwards-compatibility reasons. Setting
2109 ``warnings.showwarning()`` to an implementation that lacks support
2110 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002173- Issue #2550: The approach used by client/server code for obtaining
2174 ports to listen on in network-oriented tests has been refined in an
2175 effort to facilitate running multiple instances of the entire
2176 regression test suite in parallel without issue.
2177 test_support.bind_port() has been fixed such that it will always
2178 return a unique port -- which wasn't always the case with the
2179 previous implementation, especially if socket options had been set
2180 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2181 new implementation of bind_port() will actually raise an exception
2182 if it is passed an AF_INET/SOCK_STREAM socket with either the
2183 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2184 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2185 the socket it's been passed. This currently only applies to
2186 Windows. This option prevents any other sockets from binding to the
2187 host/port we've bound to, thus removing the possibility of the
2188 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2189 when a second SOCK_STREAM socket binds and accepts to a host/port
2190 that's already been bound by another socket. The optional preferred
2191 port parameter to bind_port() has been removed. Under no
2192 circumstances should tests be hard coding ports!
2193
2194 test_support.find_unused_port() has also been introduced, which will
2195 pass a temporary socket object to bind_port() in order to obtain an
2196 unused port. The temporary socket object is then closed and
2197 deleted, and the port is returned. This method should only be used
2198 for obtaining an unused port in order to pass to an external program
2199 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2200 a parameter to a server-oriented class that doesn't give you direct
2201 access to the underlying socket used.
2202
2203 Finally, test_support.HOST has been introduced, which should be used
2204 for the host argument of any relevant socket calls (i.e. bind and
2205 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002206
2207 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002208 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002209 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2210 test_asynchat and test_socket_ssl.
2211
Georg Brandl3ee81df2008-05-17 18:14:43 +00002212 It is now possible for multiple instances of the regression test
2213 suite to run in parallel without issue.

2480-----------------
2481
Fred Drakea8ee94b2008-03-01 02:45:07 +00002482- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002483 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002485- Issue #2067: file.__exit__() now calls subclasses' close() method.
2486
2487- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002488
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002489- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002490 issue 215555 for a discussion.
2491
Eric Smitha73fbe72008-02-23 03:09:44 +00002492- Added the future_builtins module, which contains hex() and oct().
2493 These are the PEP 3127 version of these functions, designed to be
2494 compatible with the hex() and oct() builtins from Python 3.0. They
2495 differ slightly in their output formats from the existing, unchanged
2496 Python 2.6 builtins. The expected usage of the future_builtins
2497 module is:
2498 from future_builtins import hex, oct
2499
Eric Smith7ef40bf2008-02-20 23:34:22 +00002500- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2501 exponents for exponents with absolute value < 100. Follows C99
2502 standard. This is a change on Windows, which would use 3 digits.
2503 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2504 so that any alterations it does to the resulting string will be
2505 available in stringlib/formatter.h (for float.__format__).
2506
Eric Smith5a3c1352008-02-19 13:21:56 +00002507- Implemented PEP 3101, Advanced String Formatting. This adds a new
2508 builtin format(); a format() method for str and unicode; a
2509 __format__() method to object, str, unicode, int, long, float, and
2510 datetime; the class string.Formatter; and the C API
2511 PyObject_Format().
2512
Georg Brandl3ee81df2008-05-17 18:14:43 +00002513- Fixed several potential crashes, all caused by specially crafted
2514 __del__ methods exploiting objects in temporarily inconsistent
2515 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002516
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002517- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002518 prevent a possible crash: an Abstract Base Class would try to access
2519 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002520

2522 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002523
Georg Brandl3ee81df2008-05-17 18:14:43 +00002524- Clear all free lists during a gc.collect() of the highest generation
2525 in order to allow pymalloc to free more arenas. Python may give back
2526 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002527
Georg Brandl3ee81df2008-05-17 18:14:43 +00002528- Issue #2045: Fix an infinite recursion triggered when printing a
2529 subclass of collections.defaultdict, if its default_factory is set
2530 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002531
Christian Heimesf75dbef2008-02-08 00:11:31 +00002532- Fixed a minor memory leak in dictobject.c. The content of the free
2533 list was not freed on interpreter shutdown.
2534
Georg Brandl3ee81df2008-05-17 18:14:43 +00002535- Limit free list of method and builtin function objects to 256
2536 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002537
Georg Brandl3ee81df2008-05-17 18:14:43 +00002538- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2539 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002540 to compact the internal free lists of pre-allocted ints and floats.
2541
Georg Brandl3ee81df2008-05-17 18:14:43 +00002542- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2543 calls. Python expected the return type int but the fork familie
2544 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002545
Georg Brandl3ee81df2008-05-17 18:14:43 +00002546- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2547 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002558- Patch #1473257: generator objects gain a gi_code attribute. This is
2559 the same object as the func_code attribute of the function that
2560 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002561
Georg Brandl3ee81df2008-05-17 18:14:43 +00002562- Issue #1920: "while 0" statements were completely removed by the
2563 compiler, even in the presence of an "else" clause, which is
2564 supposed to be run when the condition is false. Now the compiler
2565 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002566
Guido van Rossumeead05f2008-01-24 18:21:02 +00002567- A few crashers fixed: weakref_in_del.py (issue #1377858);
2568 loosing_dict_ref.py (issue #1303614, test67.py);
2569 borrowed_ref_[34].py (not in tracker).
2570
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002571- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002572 suppressed while an extension is loaded by calling SetErrorMode in
2573 dynload_win.c. The error is still reported properly.
2574
Georg Brandl3ee81df2008-05-17 18:14:43 +00002575- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002576 several extension methods and modules do not work without unicode
2577 support.
2578
Georg Brandl26543b12008-01-21 18:36:51 +00002579- Issue #1882: when compiling code from a string, encoding cookies in the
2580 second line of code were not always recognized correctly.
2581
Georg Brandl14404b62008-01-19 19:27:05 +00002582- Issue #1679: "0x" was taken as a valid integer literal.
2583
Georg Brandl6caad7d2008-01-26 14:19:22 +00002584- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002585 added.
2586
Christian Heimesc94e2b52008-01-14 04:13:37 +00002587- sys.float_info / PyFloat_GetInfo: The floating point information
2588 object was converted from a dict to a specialized structseq object.
2589
Georg Brandl3ee81df2008-05-17 18:14:43 +00002590- Patch #1816: Added sys.flags structseq. It exposes the status of
2591 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002592
Georg Brandl3ee81df2008-05-17 18:14:43 +00002593- Objects/structseq.c: Implemented new structseq representation. The

2595 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002596
Georg Brandl3ee81df2008-05-17 18:14:43 +00002597- Patch #1700288: added a type attribute cache that caches method

2655 file can now be directly executed by passing their name to the
2656 interpreter. The directory/zipfile is automatically inserted as the
2657 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002658
Georg Brandl3ee81df2008-05-17 18:14:43 +00002659- Issue #1265: Fix a problem with sys.settrace, if the tracing
2660 function uses a generator expression when at the same time the
2661 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002662
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002663- sets and frozensets now have an isdisjoint() method.
2664
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002665- optimize the performance of builtin.sum().
2666
Neal Norwitz44f326e2007-10-05 05:29:17 +00002667- Fix warnings found by the new version of the Coverity checker.
2668
Georg Brandl3ee81df2008-05-17 18:14:43 +00002669- The enumerate() builtin function is no longer bounded to sequences
2670 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2671 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002672
Georg Brandl3ee81df2008-05-17 18:14:43 +00002673- Issue #1686386: Tuple's tp_repr did not take into account the
2674 possibility of having a self-referential tuple, which is possible
2675 from C code. Nor did object's tp_str consider that a type's tp_str
2676 could do something that could lead to an inifinite recursion.
2677 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2678 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002679
Georg Brandl3ee81df2008-05-17 18:14:43 +00002680- Issue #1164: It was possible to trigger deadlock when using the
2681 'print' statement to write to a file since the GIL was not released
2682 as needed. Now PyObject_Print() does the right thing along with
2683 various tp_print implementations of the built-in types and those in
2684 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002685
Georg Brandl3ee81df2008-05-17 18:14:43 +00002686- Issue #1147: Exceptions were directly allowing string exceptions in
2687 their throw() method even though string exceptions no longer
2688 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002689
Georg Brandl3ee81df2008-05-17 18:14:43 +00002690- Issue #1096: Prevent a segfault from getting the repr of a very
2691 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002692
Brett Cannon1e534b52007-09-07 04:18:30 +00002693- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002694 PyObject_Call() never calling back out to Python code to trigger
2695 recursion depth updates/checks. Required the creation of a static
2696 RuntimeError instance in case normalizing an exception put the
2697 recursion check value past its limit. Fixes crashers
2698 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002699
Georg Brandl3ee81df2008-05-17 18:14:43 +00002700- Patch #1031213: Decode source line in SyntaxErrors back to its
2701 original source encoding.

2704 with %G.
2705
Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- Prevent expandtabs() on string and unicode objects from causing a
2707 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002708

Georg Brandl3ee81df2008-05-17 18:14:43 +00002711- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00002712
Neal Norwitz0ac60192007-05-27 04:08:54 +00002713- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002714 __*__ attributes. (Some already existed, e.g., __doc__ and
2715 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002716
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002717- Add -3 option to the interpreter to warn about features that are
2718 deprecated and will be changed/removed in Python 3.0.
2719
Georg Brandl2134e752007-05-21 20:34:16 +00002720- Patch #1686487: you can now pass any mapping after '**' in function
2721 calls.
2722
Collin Winter62903052007-05-18 23:11:24 +00002723- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002724 "except E as target:". This is to provide forwards compatibility
2725 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002726
Brett Cannon229cee22007-05-05 01:34:02 +00002727- Deprecate BaseException.message as per PEP 352.
2728
Georg Brandl3ee81df2008-05-17 18:14:43 +00002729- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002730 inherited from a builtin base.
2731
Vinay Sajip8549ce32007-05-06 17:53:37 +00002732- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002733 setting a plain string, ie don't expand to single letter identifiers.
2734
Raymond Hettinger13936692007-04-11 18:40:58 +00002735- Request #1191699: Slices can now be pickled.
2736
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002737- Request #1193128: str.translate() now allows a None argument for
2738 translations that only remove characters without re-mapping the
2739 remaining characters.
2740
Georg Brandl5cb76c12007-03-21 09:00:39 +00002741- Patch #1682205: a TypeError while unpacking an iterable is no longer
2742 masked by a generic one with the message "unpack non-sequence".
2743
Neal Norwitzaa754b72007-03-21 06:39:48 +00002744- Remove unused file Python/fmod.c.
2745
Guido van Rossum143b5642007-03-23 04:58:42 +00002746- Bug #1683368: The object.__init__() and object.__new__() methods are
2747 now stricter in rejecting excess arguments. The only time when
2748 either allows excess arguments is when it is not overridden and the
2749 other one is. For backwards compatibility, when both are
2750 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002751 warning later). Also, type.__init__() insists on the same signature
2752 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002753
Georg Brandl3ee81df2008-05-17 18:14:43 +00002754- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2755 object to complex using its __complex__() method before falling back
2756 to the __float__() method. Therefore, the functions in the cmath
2757 module now can operate on objects that define a __complex__()
2758 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002759
Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Patch #1623563: allow __class__ assignment for classes with
2761 __slots__. The old and the new class are still required to have the
2762 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002763
Georg Brandl3ee81df2008-05-17 18:14:43 +00002764- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002767- Patch #1462488: Python no longer segfaults when
2768 ``object.__reduce_ex__()`` is called with an object that is faking
2769 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002770
Georg Brandl3ee81df2008-05-17 18:14:43 +00002771- Patch #1680015: Don't modify __slots__ tuple if it contains an
2772 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00002774- Patch #1444529: the builtin compile() now accepts keyword arguments.
2775
Georg Brandl7b9c5552007-03-12 14:30:05 +00002776- Bug #1678647: write a newline after printing an exception in any
2777 case, even when converting the value to a string failed.
2778
Georg Brandl871f1bc2007-03-12 13:17:36 +00002779- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002780 its argument, if it exists. If not, it will work like before. This
2781 allows customizing the output of dir() in the presence of a
2782 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002783
Collin Winter276887b2007-03-12 16:11:39 +00002784- Patch #922167: Python no longer segfaults when faced with infinitely
2785 self-recursive reload() calls (as reported by bug #742342).
2786
Georg Brandl3ee81df2008-05-17 18:14:43 +00002787- Patch #1675981: remove unreachable code from ``type.__new__()``
2788 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00002789
Georg Brandl3ee81df2008-05-17 18:14:43 +00002790- Patch #1491866: change the complex() constructor to allow
2791 parthensized forms. This means complex(repr(x)) now works instead of
2792 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002793
Georg Brandlaa2321b2007-03-07 00:40:28 +00002794- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002795 makes the filenames the warning module prints much more sensible
2796 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002797
Georg Brandl49aafc92007-03-07 00:34:46 +00002798- Variant of patch #697613: don't exit the interpreter on a SystemExit
2799 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002800 variable is given, but break into the interactive interpreter just
2801 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00002802
Georg Brandl3ee81df2008-05-17 18:14:43 +00002803- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002806- Bug #1674503: close the file opened by execfile() in an error
2807 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002808
Georg Brandl0fca97a2007-03-05 22:28:08 +00002809- Patch #1674228: when assigning a slice (old-style), check for the
2810 sq_ass_slice instead of the sq_slice slot.
2811
Georg Brandl3ee81df2008-05-17 18:14:43 +00002812- When printing an unraisable error, don't print exceptions. before
2813 the name. This duplicates the behavior whening normally printing
2814 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002815
Georg Brandl3ee81df2008-05-17 18:14:43 +00002816- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00002822- Bug #1377858: Fix the segfaulting of the interpreter when an object
2823 created a weakref on itself during a __del__ call for new-style
2824 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00002825
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00002826- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

Georg Brandl2c1375c2006-10-12 11:27:59 +00002864- Bug #1545497: when given an explicit base, int() did ignore NULs
2865 embedded in the string to convert.
2866
Georg Brandl846f73a2006-10-08 07:11:54 +00002867- Bug #1569998: break inside a try statement (outside a loop) is now
2868 recognized and rejected.

2871
Armin Rigo7ccbca92006-10-04 12:17:45 +00002872- A number of places, including integer negation and absolute value,
2873 were fixed to not rely on undefined behaviour of the C compiler
2874 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00002875
Georg Brandl3267d282006-09-30 09:03:42 +00002876- Bug #1566800: make sure that EnvironmentError can be called with any
2877 number of arguments, as was the case in Python 2.4.
2878
Georg Brandl5d59c092006-09-30 08:43:30 +00002879- Patch #1567691: super() and new.instancemethod() now don't accept
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880 keyword arguments any more (previously they accepted them, but
2881 didn't use them).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002883- Fix a bug in the parser's future statement handling that led to
2884 "with" not being recognized as a keyword after, e.g., this
2885 statement: from __future__ import division, with_statement

3442 -- the failure just occurred later, with a more cumbersome
3443 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003724- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3725 with RFC 3207 and forgets any knowledge obtained from the server not
3726 obtained from the TLS negotiation itself. Patch contributed by Bill
3727 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003728
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003730 that the SMTP.starttls() caller no longer needs to call ehlo()
3731 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003732 does not claim to support starttls. Adds the
3733 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3734 Fenner.

3814 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3815 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00003817

Georg Brandl3ee81df2008-05-17 18:14:43 +00003832 time so that opening a database previously created with the DB_DUP
3833 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3834 opens. Specifically: dictionary assignment to a DB object will
3835 replace all values for a given key when the database allows
3836 duplicate values. DB users should use DB.put(k, v) when they want
3837 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003838

3844 characters with ASCII value less than 32. Also, it correctly quotes
3845 dots only if they occur on a single line, as opposed to the previous
3846 behavior of quoting dots if they are the second character of any
3847 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003848

4170-----
4171
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172- Unified naming convention for free lists and their limits. All free
4173 lists in Object/ are named ``free_list``, the counter ``numfree``

4175 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004176
Georg Brandl3ee81df2008-05-17 18:14:43 +00004177- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4178 to ``PyTuple_SetItem``, it can be used to populate a brand new

4191
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4193 of w# format code incorrectly truncated the length to an int, even
4194 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4195 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4215- Fix some leftovers from the conversion from int to Py_ssize_t
4216 (relevant to strings and sequences of more than 2**31 items).
4217
4218- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4219 outside of pystate.c and should not be necessary.
4220
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4222 absolute imports. In earlier versions they might have used relative
4223 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004224
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4226 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004227
Georg Brandl3ee81df2008-05-17 18:14:43 +00004228- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4236 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4237 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4238 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004239

Georg Brandl3ee81df2008-05-17 18:14:43 +00004253- Removed the macfs module. It had been deprecated since Python 2.5.
4254 This lead to the deprecation of macostools.touched() as it relied
4255 solely on macfs and was a no-op under OS X.
