988What's New in Python 2.6.1
989==========================
990
991*Release date: 04-Dec-2008*
992
993Core and Builtins
994-----------------
995
996- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
997 interpreter to abort ("Fatal Python error: Could not reset the stack!")
998 instead of throwing a MemoryError.
999
1000- Issue #4367: Python would segfault during compiling when the unicodedata
1001 module couldn't be imported and \N escapes were present.
1002
1003- Issue #4348: Some bytearray methods returned that didn't cause any change to
1004 the bytearray, returned the same bytearray instead of a copy.
1005
1006- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1007
1008- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1009
1010- Issue #4048: The parser module now correctly validates relative imports.
1011
1012- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1013 exec statement.
1014
1015- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1016 method does not return iterators for the 4th and 5th items.
1017
1018- Issue #4209: Enabling unicode_literals and the print_function in the same
1019 __future__ import didn't work.
1020
1021- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1022 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1023 really executed because I cannot move to such directory on win2k)
1024
1025- Issue #4069: When set.remove(element) is used with a set element, the element
1026 is temporarily replaced with an equivalent frozenset. But the eventual
1027 KeyError would always report the empty frozenset([]) as the missing key. Now
1028 it correctly refers to the initial element.
1029
1030- Fixed C99 style comments in several files. Python is now C89 compatible
1031 again.

1179
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001180- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1181 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1182 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1183 ``printf`` function, whereas PyString_FromFormat has an independent
1184 implementation and uses "%zd" on all platforms for size_t values.
1185 This makes a difference on win64, where ``printf`` needs "%Id" to display
1186 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001206 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1207 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1208 when given a tuple of classes as second argument, were looking up
1209 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1210 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001346What's New in Python 2.6 beta 3?
1347================================
1348
Barry Warsaw07a4a382008-08-21 01:15:08 +00001349*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001350
1351Core and Builtins
1352-----------------
1353
Guido van Rossumf8402962008-08-20 15:01:50 +00001354- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1355 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1356 extensions do not automatically benefit from the class attribute
1357 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1358 to their tp_flags field if they care. This is a backwards
1359 compatibility feature; in 3.0, all types will use the cache by
1360 default.
1361
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001362- Keyword arguments can now follow starred arguments. (``f(a, *args,
1363 keyword=23)`` is now valid syntax.)
1364
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001365- ctypes function pointers that are COM methods have a boolean True
1366 value again.
1367
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001368- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1369 by denying s# to parse objects that have a releasebuffer procedure,
1370 and introducing s*.
1371
Georg Brandl1e13ea92008-08-11 09:07:59 +00001372- Issue #3537: Fix an assertion failure when an empty but presized dict
1373 object was stored in the freelist.
1374
Mark Dickinsonb6467572008-08-04 21:30:09 +00001375- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1376 ValueError consistently across platforms.
1377
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001378- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1379 (64bit Unix, for example), unichr() would truncate its argument and return
1380 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1381
Neal Norwitze7d8be82008-07-31 17:17:14 +00001382- Apply security patches from Apple.
1383
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001384- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1385 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1386
Antoine Pitrou92f82162008-07-25 22:22:08 +00001387- Issue #1819: function calls with several named parameters are now on
1388 average 35% faster (as measured by pybench).
1389
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001390- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1391 the python debugger steps into a class statement: the free variables (local
1392 variables defined in an outer scope) would be deleted from the outer scope.
1393
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001394- Issue #2620: Overflow checking when allocating or reallocating memory
1395 was not always being done properly in some python types and extension
1396 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1397 all been updated to perform better checks and places in the code that
1398 would previously leak memory on the error path when such an allocation
1399 failed have been fixed.
1400
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001401Library
1402-------
1403
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001404- Issue #3612: Added some missing basic types in ctypes.wintypes.
1405
Benjamin Petersone977ad42008-08-20 01:42:01 +00001406- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1407 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1408
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001409- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1410 version reported by these tools does not necessarily follow the python
1411 version numbering scheme, so the module is less strict when parsing it.
1412
Nick Coghlanf70385a2008-08-18 12:42:46 +00001413- Issue #2235: Added Py3k warnings for types which will become unhashable
1414 under the stricter __hash__ inheritance rules in 3.0. Several types
1415 which did not meet the rules for hash invariants and were already
1416 unhashable in 3.0 have now been explicitly flagged as unhashable in
1417 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1418 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1419
Brett Cannon88f801d2008-08-18 00:46:22 +00001420- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1421 imported into the module but exposed as part of the module's API.
1422
Brett Cannon7b96f072008-08-18 00:41:11 +00001423- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1424
Brett Cannon46225e72008-08-18 00:36:52 +00001425- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1426
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001427- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1428
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001429- Issue #3575: Incremental decoder's decode function now takes bytearray
1430 by using 's*' instead of 't#'.
1431
Jesus Cea585ad8a2009-07-02 15:37:21 +00001432- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001433 fails unicode conversion on 2nd parameter. (windows only)
1434
Facundo Batista94f243a2008-08-17 03:38:39 +00001435- Issue 2464. urllib2 now supports a malformation in the URL received
1436 in a redirect.
1437
Brett Cannonabe423e2008-08-16 21:47:07 +00001438- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001439 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001440
Facundo Batistaeb90b782008-08-16 14:44:07 +00001441- Issue #2776: fixed small issue when handling an URL with double slash
1442 after a 302 response in the case of not going through a proxy.
1443
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001444- Issue #2676: in the email package, content-type parsing was hanging on
1445 pathological input because of quadratic or exponential behaviour of a
1446 regular expression.
1447
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001448- Issue #3476: binary buffered reading through the new "io" library is now
1449 thread-safe.
1450
Brett Cannonbf3157b2008-08-14 05:00:03 +00001451- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1452 since mimetools itself is deprecated. Because modules are cached, all
1453 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1454
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001455- Issue #3134: shutil referenced undefined WindowsError symbol.
1456
Robert Schuppenies14646332008-08-10 11:01:53 +00001457- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1458 menu entries were not deleted.
1459
Brett Cannon83e81842008-08-09 23:30:55 +00001460- Copied the implementation of reduce() to _functools.reduce() to have a
1461 version that did not raise a DeprecationWarning under -3.
1462
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001463- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1464 a MemoryError rather than silently stop the iteration.
1465
Guido van Rossum59ce9012008-08-09 14:55:34 +00001466- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1467 to _sre.compile() will now be rejected. This should not affect anybody
1468 since the re.compile() function never generates invalid re-bytecode.
1469
Skip Montanaroa032bf42008-08-08 22:52:51 +00001470- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1471 upon first access it can be automatically initialized from the csv file if
1472 it wasn't initialized during instantiation.
1473
Brett Cannon3aa2a492008-08-06 22:28:09 +00001474- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1475 the reload() built-in has been removed.
1476
Brett Cannon7e30b672008-08-04 21:52:25 +00001477- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001478 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1481 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1482 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1483 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001484
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001485- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1486 raised an AttributeError.
1487
Benjamin Peterson01a24322008-07-28 23:35:27 +00001488- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001489 asking for a specific length. This problem only affected files opened
1490 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001491
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001492- Issue #3449: Update decimal module to use most recent specification
1493 (v. 1.68) and tests (v. 2.58) from IBM.
1494
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001495- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1496

1503
1504- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1505 invalid arguments.
1506
1507- Issue #3302: Fix several crashes when calling locale's gettext functions
1508 with None arguments.
1509
1510- Issue #3389: Allow resolving dotted names for handlers in logging
1511 configuration files.
1512
1513- Deprecate the sunaudio module for removal in Python 3.0.
1514
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001515- Issue #3394: zipfile.writestr sets external attributes when passed a
1516 file name rather than a ZipInfo instance, so files are extracted with
1517 mode 0600 rather than 000 under Unix.
1518
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001519- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1520 argument in python 2.5, this broke code that subclassed Popen to include its
1521 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1529-------------
1530
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001531- Issue #2235: the C API function PyObject_HashNotImplemented and its
1532 interaction with the tp_hash slot (added in 2.6b2) are now documented
1533
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001534- Issue #643841: The language reference now provides more detailed
1535 coverage of the lookup process for special methods. The disclaimers
1536 regarding lack of coverage of new-style classes have also been
1537 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001540What's New in Python 2.6 beta 2?
1541================================
1542
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001543*Release date: 17-Jul-2008*
1544
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001545Core and Builtins
1546-----------------
1547
Georg Brandl3e483f62008-07-16 22:57:41 +00001548- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1549 its methods now allow for items objects that can be converted to
1550 an integer using operator.index().
1551
Mark Dickinson64b7e502008-07-16 09:40:03 +00001552- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1553 produced a ValueError instead of giving the correct float.
1554
Eric Smitha5fa5a22008-07-16 00:11:49 +00001555- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1556 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1557
Mark Dickinson7103aa42008-07-15 19:08:33 +00001558- Issue #3008: the float type has a new instance method 'float.hex'
1559 and a new class method 'float.fromhex' to convert floating-point
1560 numbers to and from hexadecimal strings, respectively.
1561
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001562- Issue #2235: __hash__ is once again inherited by default. To allow
1563 collections.Hashable to remain meaningful in the presence of the
1564 default hash implementation (object.__hash__), it is now possible
1565 to explicit block inheritance of hash by setting __hash__=None at
1566 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1567 level.
1568
Nick Coghlanb028f502008-07-13 14:52:36 +00001569- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1570 the parent module cannot be found while performing an absolute import.
1571 This means that an incorrectly defined __package__ attribute will
1572 now only prevent relative imports in that module rather than causing
1573 all imports from that module to fail.
1574
Nick Coghlan14ff9942008-07-08 14:21:42 +00001575- Issue #2517: Allow unicode messages in Exceptions again by correctly
1576 bypassing the instance dictionary when looking up __unicode__ on
1577 new-style classes.
1578
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001579- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1580 set to a custom object whose write() method happens to install
1581 another file in sys.stdout.
1582
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001583- Issue #3088: Corrected a race condition in classes derived from

1585 another thread's dictionary.
1586
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001587- Issue #3004: Minor change to slice.indices(): the start and stop
1588 arguments are now treated identically, making the behaviour easier
1589 to describe and understand. For example, slice(None, -10,
1590 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1591 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1592 10, -1).
1593
Georg Brandl278fc502008-07-19 12:46:12 +00001594- Issue #3219: Calling a function with repeated keyword arguments,
1595 f(a=2, a=23), would not cause a syntax error. This was a regression
1596 from 2.4 caused by the switch to the new compiler.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002108- Issue #1631171: Re-implement the 'warnings' module in C (the
2109 original Python code has been kept as backup). This will allow for
2110 using the 'warning's machinery in such places as the parser where
2111 use of pure Python code is not possible. Both the ``showarning()``
2112 and ``formatwarning()`` gain an optional 'line' argument which is
2113 not called by default for backwards-compatibility reasons. Setting
2114 ``warnings.showwarning()`` to an implementation that lacks support
2115 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002178- Issue #2550: The approach used by client/server code for obtaining
2179 ports to listen on in network-oriented tests has been refined in an
2180 effort to facilitate running multiple instances of the entire
2181 regression test suite in parallel without issue.
2182 test_support.bind_port() has been fixed such that it will always
2183 return a unique port -- which wasn't always the case with the
2184 previous implementation, especially if socket options had been set
2185 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2186 new implementation of bind_port() will actually raise an exception
2187 if it is passed an AF_INET/SOCK_STREAM socket with either the
2188 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2189 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2190 the socket it's been passed. This currently only applies to
2191 Windows. This option prevents any other sockets from binding to the
2192 host/port we've bound to, thus removing the possibility of the
2193 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2194 when a second SOCK_STREAM socket binds and accepts to a host/port
2195 that's already been bound by another socket. The optional preferred
2196 port parameter to bind_port() has been removed. Under no
2197 circumstances should tests be hard coding ports!
2198
2199 test_support.find_unused_port() has also been introduced, which will
2200 pass a temporary socket object to bind_port() in order to obtain an
2201 unused port. The temporary socket object is then closed and
2202 deleted, and the port is returned. This method should only be used
2203 for obtaining an unused port in order to pass to an external program
2204 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2205 a parameter to a server-oriented class that doesn't give you direct
2206 access to the underlying socket used.
2207
2208 Finally, test_support.HOST has been introduced, which should be used
2209 for the host argument of any relevant socket calls (i.e. bind and
2210 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002211
2212 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002213 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002214 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2215 test_asynchat and test_socket_ssl.
2216
Georg Brandl3ee81df2008-05-17 18:14:43 +00002217 It is now possible for multiple instances of the regression test
2218 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00002422- The bundled libffi copy is now in sync with the recently released
2423 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002424 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2425 files are used. On all linux systems the --with-system-ffi
2426 configure option defaults to "yes".

2485-----------------
2486
Fred Drakea8ee94b2008-03-01 02:45:07 +00002487- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002488 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002489
Georg Brandlad61bc82008-02-23 15:11:18 +00002490- Issue #2067: file.__exit__() now calls subclasses' close() method.
2491
2492- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002493
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002494- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002495 issue 215555 for a discussion.
2496
Eric Smitha73fbe72008-02-23 03:09:44 +00002497- Added the future_builtins module, which contains hex() and oct().
2498 These are the PEP 3127 version of these functions, designed to be
2499 compatible with the hex() and oct() builtins from Python 3.0. They
2500 differ slightly in their output formats from the existing, unchanged
2501 Python 2.6 builtins. The expected usage of the future_builtins
2502 module is:
2503 from future_builtins import hex, oct
2504
Eric Smith7ef40bf2008-02-20 23:34:22 +00002505- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2506 exponents for exponents with absolute value < 100. Follows C99
2507 standard. This is a change on Windows, which would use 3 digits.
2508 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2509 so that any alterations it does to the resulting string will be
2510 available in stringlib/formatter.h (for float.__format__).
2511
Eric Smith5a3c1352008-02-19 13:21:56 +00002512- Implemented PEP 3101, Advanced String Formatting. This adds a new
2513 builtin format(); a format() method for str and unicode; a
2514 __format__() method to object, str, unicode, int, long, float, and
2515 datetime; the class string.Formatter; and the C API
2516 PyObject_Format().
2517
Georg Brandl3ee81df2008-05-17 18:14:43 +00002518- Fixed several potential crashes, all caused by specially crafted
2519 __del__ methods exploiting objects in temporarily inconsistent
2520 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002521
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002522- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002523 prevent a possible crash: an Abstract Base Class would try to access
2524 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002525
Georg Brandl3ee81df2008-05-17 18:14:43 +00002526- Fixed repr() and str() of complex numbers with infinity or nan as
2527 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002528
Georg Brandl3ee81df2008-05-17 18:14:43 +00002529- Clear all free lists during a gc.collect() of the highest generation
2530 in order to allow pymalloc to free more arenas. Python may give back
2531 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002532
Georg Brandl3ee81df2008-05-17 18:14:43 +00002533- Issue #2045: Fix an infinite recursion triggered when printing a
2534 subclass of collections.defaultdict, if its default_factory is set
2535 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002536
Christian Heimesf75dbef2008-02-08 00:11:31 +00002537- Fixed a minor memory leak in dictobject.c. The content of the free
2538 list was not freed on interpreter shutdown.
2539
Georg Brandl3ee81df2008-05-17 18:14:43 +00002540- Limit free list of method and builtin function objects to 256
2541 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002542
Georg Brandl3ee81df2008-05-17 18:14:43 +00002543- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2544 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002545 to compact the internal free lists of pre-allocted ints and floats.
2546
Georg Brandl3ee81df2008-05-17 18:14:43 +00002547- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2548 calls. Python expected the return type int but the fork familie
2549 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002550
Georg Brandl3ee81df2008-05-17 18:14:43 +00002551- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2552 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002553
Georg Brandl3ee81df2008-05-17 18:14:43 +00002554- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2555 with the collections.Sequence API.

2561 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002562
Georg Brandl3ee81df2008-05-17 18:14:43 +00002563- Patch #1473257: generator objects gain a gi_code attribute. This is
2564 the same object as the func_code attribute of the function that
2565 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002566
Georg Brandl3ee81df2008-05-17 18:14:43 +00002567- Issue #1920: "while 0" statements were completely removed by the
2568 compiler, even in the presence of an "else" clause, which is
2569 supposed to be run when the condition is false. Now the compiler
2570 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002571
Guido van Rossumeead05f2008-01-24 18:21:02 +00002572- A few crashers fixed: weakref_in_del.py (issue #1377858);
2573 loosing_dict_ref.py (issue #1303614, test67.py);
2574 borrowed_ref_[34].py (not in tracker).
2575
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002576- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002577 suppressed while an extension is loaded by calling SetErrorMode in
2578 dynload_win.c. The error is still reported properly.
2579
Georg Brandl3ee81df2008-05-17 18:14:43 +00002580- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002581 several extension methods and modules do not work without unicode
2582 support.
2583
Georg Brandl26543b12008-01-21 18:36:51 +00002584- Issue #1882: when compiling code from a string, encoding cookies in the
2585 second line of code were not always recognized correctly.
2586
Georg Brandl14404b62008-01-19 19:27:05 +00002587- Issue #1679: "0x" was taken as a valid integer literal.
2588
Georg Brandl6caad7d2008-01-26 14:19:22 +00002589- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002590 added.
2591
Christian Heimesc94e2b52008-01-14 04:13:37 +00002592- sys.float_info / PyFloat_GetInfo: The floating point information
2593 object was converted from a dict to a specialized structseq object.
2594
Georg Brandl3ee81df2008-05-17 18:14:43 +00002595- Patch #1816: Added sys.flags structseq. It exposes the status of
2596 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002597
Georg Brandl3ee81df2008-05-17 18:14:43 +00002598- Objects/structseq.c: Implemented new structseq representation. The

2600 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002601
Georg Brandl3ee81df2008-05-17 18:14:43 +00002602- Patch #1700288: added a type attribute cache that caches method

2628 literals. The oparg for BUILD_MAP now indicates an estimated
2629 dictionary size. There is a new opcode, STORE_MAP, for adding
2630 entries to the dictionary.

2660 file can now be directly executed by passing their name to the
2661 interpreter. The directory/zipfile is automatically inserted as the
2662 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002663
Georg Brandl3ee81df2008-05-17 18:14:43 +00002664- Issue #1265: Fix a problem with sys.settrace, if the tracing
2665 function uses a generator expression when at the same time the
2666 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002667
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002668- sets and frozensets now have an isdisjoint() method.
2669
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002670- optimize the performance of builtin.sum().
2671
Neal Norwitz44f326e2007-10-05 05:29:17 +00002672- Fix warnings found by the new version of the Coverity checker.
2673
Georg Brandl3ee81df2008-05-17 18:14:43 +00002674- The enumerate() builtin function is no longer bounded to sequences
2675 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2676 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002677
Georg Brandl3ee81df2008-05-17 18:14:43 +00002678- Issue #1686386: Tuple's tp_repr did not take into account the
2679 possibility of having a self-referential tuple, which is possible
2680 from C code. Nor did object's tp_str consider that a type's tp_str
2681 could do something that could lead to an inifinite recursion.
2682 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2683 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002684
Georg Brandl3ee81df2008-05-17 18:14:43 +00002685- Issue #1164: It was possible to trigger deadlock when using the
2686 'print' statement to write to a file since the GIL was not released
2687 as needed. Now PyObject_Print() does the right thing along with
2688 various tp_print implementations of the built-in types and those in
2689 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002690
Georg Brandl3ee81df2008-05-17 18:14:43 +00002691- Issue #1147: Exceptions were directly allowing string exceptions in
2692 their throw() method even though string exceptions no longer
2693 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002694
Georg Brandl3ee81df2008-05-17 18:14:43 +00002695- Issue #1096: Prevent a segfault from getting the repr of a very
2696 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002697
Brett Cannon1e534b52007-09-07 04:18:30 +00002698- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002699 PyObject_Call() never calling back out to Python code to trigger
2700 recursion depth updates/checks. Required the creation of a static
2701 RuntimeError instance in case normalizing an exception put the
2702 recursion check value past its limit. Fixes crashers
2703 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002704
Georg Brandl3ee81df2008-05-17 18:14:43 +00002705- Patch #1031213: Decode source line in SyntaxErrors back to its

2709 with %G.
2710
Georg Brandl3ee81df2008-05-17 18:14:43 +00002711- Prevent expandtabs() on string and unicode objects from causing a
2712 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002713

Georg Brandl3ee81df2008-05-17 18:14:43 +00002716- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00002717
Neal Norwitz0ac60192007-05-27 04:08:54 +00002718- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002719 __*__ attributes. (Some already existed, e.g., __doc__ and
2720 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002721
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002722- Add -3 option to the interpreter to warn about features that are
2723 deprecated and will be changed/removed in Python 3.0.
2724
Georg Brandl2134e752007-05-21 20:34:16 +00002725- Patch #1686487: you can now pass any mapping after '**' in function
2726 calls.
2727
Collin Winter62903052007-05-18 23:11:24 +00002728- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002729 "except E as target:". This is to provide forwards compatibility
2730 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002731
Brett Cannon229cee22007-05-05 01:34:02 +00002732- Deprecate BaseException.message as per PEP 352.
2733
Georg Brandl3ee81df2008-05-17 18:14:43 +00002734- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002735 inherited from a builtin base.
2736
Vinay Sajip8549ce32007-05-06 17:53:37 +00002737- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002738 setting a plain string, ie don't expand to single letter identifiers.
2739
Raymond Hettinger13936692007-04-11 18:40:58 +00002740- Request #1191699: Slices can now be pickled.
2741
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002742- Request #1193128: str.translate() now allows a None argument for
2743 translations that only remove characters without re-mapping the
2744 remaining characters.
2745
Georg Brandl5cb76c12007-03-21 09:00:39 +00002746- Patch #1682205: a TypeError while unpacking an iterable is no longer
2747 masked by a generic one with the message "unpack non-sequence".
2748
Neal Norwitzaa754b72007-03-21 06:39:48 +00002749- Remove unused file Python/fmod.c.
2750
Guido van Rossum143b5642007-03-23 04:58:42 +00002751- Bug #1683368: The object.__init__() and object.__new__() methods are
2752 now stricter in rejecting excess arguments. The only time when
2753 either allows excess arguments is when it is not overridden and the
2754 other one is. For backwards compatibility, when both are
2755 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002756 warning later). Also, type.__init__() insists on the same signature
2757 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002758
Georg Brandl3ee81df2008-05-17 18:14:43 +00002759- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2760 object to complex using its __complex__() method before falling back
2761 to the __float__() method. Therefore, the functions in the cmath
2762 module now can operate on objects that define a __complex__()
2763 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002764
Georg Brandl3ee81df2008-05-17 18:14:43 +00002765- Patch #1623563: allow __class__ assignment for classes with
2766 __slots__. The old and the new class are still required to have the
2767 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002768
Georg Brandl3ee81df2008-05-17 18:14:43 +00002769- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002772- Patch #1462488: Python no longer segfaults when
2773 ``object.__reduce_ex__()`` is called with an object that is faking
2774 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002775
Georg Brandl3ee81df2008-05-17 18:14:43 +00002776- Patch #1680015: Don't modify __slots__ tuple if it contains an
2777 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00002778
Georg Brandl5240d742007-03-13 20:46:32 +00002779- Patch #1444529: the builtin compile() now accepts keyword arguments.
2780
Georg Brandl7b9c5552007-03-12 14:30:05 +00002781- Bug #1678647: write a newline after printing an exception in any
2782 case, even when converting the value to a string failed.
2783
Georg Brandl871f1bc2007-03-12 13:17:36 +00002784- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002785 its argument, if it exists. If not, it will work like before. This
2786 allows customizing the output of dir() in the presence of a
2787 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002788
Collin Winter276887b2007-03-12 16:11:39 +00002789- Patch #922167: Python no longer segfaults when faced with infinitely
2790 self-recursive reload() calls (as reported by bug #742342).
2791
Georg Brandl3ee81df2008-05-17 18:14:43 +00002792- Patch #1675981: remove unreachable code from ``type.__new__()``
2793 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00002794
Georg Brandl3ee81df2008-05-17 18:14:43 +00002795- Patch #1491866: change the complex() constructor to allow
2796 parthensized forms. This means complex(repr(x)) now works instead of
2797 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002798
Georg Brandlaa2321b2007-03-07 00:40:28 +00002799- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002800 makes the filenames the warning module prints much more sensible
2801 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002802
Georg Brandl49aafc92007-03-07 00:34:46 +00002803- Variant of patch #697613: don't exit the interpreter on a SystemExit
2804 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002805 variable is given, but break into the interactive interpreter just
2806 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00002807
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002811- Bug #1674503: close the file opened by execfile() in an error
2812 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002813
Georg Brandl0fca97a2007-03-05 22:28:08 +00002814- Patch #1674228: when assigning a slice (old-style), check for the
2815 sq_ass_slice instead of the sq_slice slot.
2816
Georg Brandl3ee81df2008-05-17 18:14:43 +00002817- When printing an unraisable error, don't print exceptions. before
2818 the name. This duplicates the behavior whening normally printing
2819 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002820
Georg Brandl3ee81df2008-05-17 18:14:43 +00002821- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00002827- Bug #1377858: Fix the segfaulting of the interpreter when an object
2828 created a weakref on itself during a __del__ call for new-style
2829 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00002830
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00002831- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

Georg Brandl2c1375c2006-10-12 11:27:59 +00002869- Bug #1545497: when given an explicit base, int() did ignore NULs
2870 embedded in the string to convert.
2871
Georg Brandl846f73a2006-10-08 07:11:54 +00002872- Bug #1569998: break inside a try statement (outside a loop) is now
2873 recognized and rejected.

2876
Armin Rigo7ccbca92006-10-04 12:17:45 +00002877- A number of places, including integer negation and absolute value,
2878 were fixed to not rely on undefined behaviour of the C compiler
2879 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00002880
Georg Brandl3267d282006-09-30 09:03:42 +00002881- Bug #1566800: make sure that EnvironmentError can be called with any

2883
Georg Brandl5d59c092006-09-30 08:43:30 +00002884- Patch #1567691: super() and new.instancemethod() now don't accept

Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Fix a bug in the parser's future statement handling that led to
2889 "with" not being recognized as a keyword after, e.g., this
2890 statement: from __future__ import division, with_statement

3447 -- the failure just occurred later, with a more cumbersome
3448 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003729- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3730 with RFC 3207 and forgets any knowledge obtained from the server not
3731 obtained from the TLS negotiation itself. Patch contributed by Bill
3732 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003733
Georg Brandl3ee81df2008-05-17 18:14:43 +00003734- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003735 that the SMTP.starttls() caller no longer needs to call ehlo()
3736 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003737 does not claim to support starttls. Adds the
3738 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3739 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003793- itertools.chain() now has an alternate constructor,

3819 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3820 silently miscode subclasses of those types. Now, it raises a
3821 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003822

Georg Brandl3ee81df2008-05-17 18:14:43 +00003837 time so that opening a database previously created with the DB_DUP
3838 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3839 opens. Specifically: dictionary assignment to a DB object will
3840 replace all values for a given key when the database allows
3841 duplicate values. DB users should use DB.put(k, v) when they want
3842 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003843

3849 characters with ASCII value less than 32. Also, it correctly quotes
3850 dots only if they occur on a single line, as opposed to the previous
3851 behavior of quoting dots if they are the second character of any
3852 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003853

4175-----
4176
Georg Brandl3ee81df2008-05-17 18:14:43 +00004177- Unified naming convention for free lists and their limits. All free
4178 lists in Object/ are named ``free_list``, the counter ``numfree``
4179 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4180 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004181
Georg Brandl3ee81df2008-05-17 18:14:43 +00004182- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4183 to ``PyTuple_SetItem``, it can be used to populate a brand new
4184 frozenset; but it does not steal a reference to the added item.

4196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4198 of w# format code incorrectly truncated the length to an int, even
4199 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4200 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004201
Georg Brandl3ee81df2008-05-17 18:14:43 +00004202- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4220- Fix some leftovers from the conversion from int to Py_ssize_t
4221 (relevant to strings and sequences of more than 2**31 items).
4222
4223- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4224 outside of pystate.c and should not be necessary.
4225
Georg Brandl3ee81df2008-05-17 18:14:43 +00004226- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4227 absolute imports. In earlier versions they might have used relative
4228 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004229
Georg Brandl3ee81df2008-05-17 18:14:43 +00004230- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4231 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004232
Georg Brandl3ee81df2008-05-17 18:14:43 +00004233- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4241 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4242 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4243 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004244

Georg Brandl3ee81df2008-05-17 18:14:43 +00004258- Removed the macfs module. It had been deprecated since Python 2.5.
4259 This lead to the deprecation of macostools.touched() as it relied
4260 solely on macfs and was a no-op under OS X.
