1063What's New in Python 2.6.1
1064==========================
1065
1066*Release date: 04-Dec-2008*
1067
1068Core and Builtins
1069-----------------
1070
1071- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1072 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1073 instead of throwing a MemoryError.
1074
1075- Issue #4367: Python would segfault during compiling when the unicodedata
1076 module couldn't be imported and \N escapes were present.
1077
1078- Issue #4348: Some bytearray methods returned that didn't cause any change to
1079 the bytearray, returned the same bytearray instead of a copy.
1080
1081- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1082
1083- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1084
1085- Issue #4048: The parser module now correctly validates relative imports.
1086
1087- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1091 method does not return iterators for the 4th and 5th items.
1092
1093- Issue #4209: Enabling unicode_literals and the print_function in the same
1094 __future__ import didn't work.
1095
1096- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1097 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1098 really executed because I cannot move to such directory on win2k)
1099
1100- Issue #4069: When set.remove(element) is used with a set element, the element
1101 is temporarily replaced with an equivalent frozenset. But the eventual
1102 KeyError would always report the empty frozenset([]) as the missing key. Now
1103 it correctly refers to the initial element.
1104
1105- Fixed C99 style comments in several files. Python is now C89 compatible
1106 again.

1254
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001255- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1256 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1257 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1258 ``printf`` function, whereas PyString_FromFormat has an independent
1259 implementation and uses "%zd" on all platforms for size_t values.
1260 This makes a difference on win64, where ``printf`` needs "%Id" to display
1261 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001263- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitrou0668c622008-08-26 22:42:08 +00001281 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1282 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1284 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1285 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001421What's New in Python 2.6 beta 3?
1422================================
1423
Barry Warsaw07a4a382008-08-21 01:15:08 +00001424*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001425
1426Core and Builtins
1427-----------------
1428
Guido van Rossumf8402962008-08-20 15:01:50 +00001429- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1430 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1431 extensions do not automatically benefit from the class attribute
1432 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1433 to their tp_flags field if they care. This is a backwards
1434 compatibility feature; in 3.0, all types will use the cache by
1435 default.
1436
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001437- Keyword arguments can now follow starred arguments. (``f(a, *args,
1438 keyword=23)`` is now valid syntax.)
1439
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001440- ctypes function pointers that are COM methods have a boolean True
1441 value again.
1442
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001443- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1444 by denying s# to parse objects that have a releasebuffer procedure,
1445 and introducing s*.
1446
Georg Brandl1e13ea92008-08-11 09:07:59 +00001447- Issue #3537: Fix an assertion failure when an empty but presized dict
1448 object was stored in the freelist.
1449
Mark Dickinsonb6467572008-08-04 21:30:09 +00001450- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1451 ValueError consistently across platforms.
1452
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001453- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1454 (64bit Unix, for example), unichr() would truncate its argument and return
1455 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1456
Neal Norwitze7d8be82008-07-31 17:17:14 +00001457- Apply security patches from Apple.
1458
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001459- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1460 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1461
Antoine Pitrou92f82162008-07-25 22:22:08 +00001462- Issue #1819: function calls with several named parameters are now on
1463 average 35% faster (as measured by pybench).
1464
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001465- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1466 the python debugger steps into a class statement: the free variables (local
1467 variables defined in an outer scope) would be deleted from the outer scope.
1468
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001469- Issue #2620: Overflow checking when allocating or reallocating memory
1470 was not always being done properly in some python types and extension
1471 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1472 all been updated to perform better checks and places in the code that
1473 would previously leak memory on the error path when such an allocation
1474 failed have been fixed.

1478
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001479- Issue #3612: Added some missing basic types in ctypes.wintypes.
1480
Benjamin Petersone977ad42008-08-20 01:42:01 +00001481- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1482 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1483
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001484- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1485 version reported by these tools does not necessarily follow the python
1486 version numbering scheme, so the module is less strict when parsing it.
1487
Nick Coghlanf70385a2008-08-18 12:42:46 +00001488- Issue #2235: Added Py3k warnings for types which will become unhashable
1489 under the stricter __hash__ inheritance rules in 3.0. Several types
1490 which did not meet the rules for hash invariants and were already
1491 unhashable in 3.0 have now been explicitly flagged as unhashable in
1492 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1493 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1494
Brett Cannon88f801d2008-08-18 00:46:22 +00001495- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1496 imported into the module but exposed as part of the module's API.
1497
Brett Cannon7b96f072008-08-18 00:41:11 +00001498- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1499
Brett Cannon46225e72008-08-18 00:36:52 +00001500- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001502- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1503
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001504- Issue #3575: Incremental decoder's decode function now takes bytearray
1505 by using 's*' instead of 't#'.
1506
Jesus Cea585ad8a2009-07-02 15:37:21 +00001507- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001508 fails unicode conversion on 2nd parameter. (windows only)
1509
Facundo Batista94f243a2008-08-17 03:38:39 +00001510- Issue 2464. urllib2 now supports a malformation in the URL received
1511 in a redirect.
1512
Brett Cannonabe423e2008-08-16 21:47:07 +00001513- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001514 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001515
Facundo Batistaeb90b782008-08-16 14:44:07 +00001516- Issue #2776: fixed small issue when handling an URL with double slash
1517 after a 302 response in the case of not going through a proxy.
1518
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001519- Issue #2676: in the email package, content-type parsing was hanging on
1520 pathological input because of quadratic or exponential behaviour of a
1521 regular expression.
1522
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001523- Issue #3476: binary buffered reading through the new "io" library is now
1524 thread-safe.
1525
Brett Cannonbf3157b2008-08-14 05:00:03 +00001526- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1527 since mimetools itself is deprecated. Because modules are cached, all
1528 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1529
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001530- Issue #3134: shutil referenced undefined WindowsError symbol.
1531
Robert Schuppenies14646332008-08-10 11:01:53 +00001532- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1533 menu entries were not deleted.
1534
Brett Cannon83e81842008-08-09 23:30:55 +00001535- Copied the implementation of reduce() to _functools.reduce() to have a
1536 version that did not raise a DeprecationWarning under -3.
1537
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001538- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1539 a MemoryError rather than silently stop the iteration.
1540
Guido van Rossum59ce9012008-08-09 14:55:34 +00001541- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1542 to _sre.compile() will now be rejected. This should not affect anybody
1543 since the re.compile() function never generates invalid re-bytecode.
1544
Skip Montanaroa032bf42008-08-08 22:52:51 +00001545- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1546 upon first access it can be automatically initialized from the csv file if
1547 it wasn't initialized during instantiation.
1548
Brett Cannon3aa2a492008-08-06 22:28:09 +00001549- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1550 the reload() built-in has been removed.
1551
Brett Cannon7e30b672008-08-04 21:52:25 +00001552- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001553 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001564 asking for a specific length. This problem only affected files opened
1565 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001566

Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001594- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1595 argument in python 2.5, this broke code that subclassed Popen to include its
1596 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1607 interaction with the tp_hash slot (added in 2.6b2) are now documented
1608
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001609- Issue #643841: The language reference now provides more detailed
1610 coverage of the lookup process for special methods. The disclaimers
1611 regarding lack of coverage of new-style classes have also been
1612 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001615What's New in Python 2.6 beta 2?
1616================================
1617
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001618*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001620Core and Builtins
1621-----------------
1622
Georg Brandl3e483f62008-07-16 22:57:41 +00001623- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1624 its methods now allow for items objects that can be converted to
1625 an integer using operator.index().
1626
Mark Dickinson64b7e502008-07-16 09:40:03 +00001627- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1628 produced a ValueError instead of giving the correct float.
1629
Eric Smitha5fa5a22008-07-16 00:11:49 +00001630- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1631 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1632
Mark Dickinson7103aa42008-07-15 19:08:33 +00001633- Issue #3008: the float type has a new instance method 'float.hex'
1634 and a new class method 'float.fromhex' to convert floating-point
1635 numbers to and from hexadecimal strings, respectively.
1636
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001637- Issue #2235: __hash__ is once again inherited by default. To allow
1638 collections.Hashable to remain meaningful in the presence of the
1639 default hash implementation (object.__hash__), it is now possible
1640 to explicit block inheritance of hash by setting __hash__=None at
1641 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1642 level.
1643
Nick Coghlanb028f502008-07-13 14:52:36 +00001644- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1645 the parent module cannot be found while performing an absolute import.
1646 This means that an incorrectly defined __package__ attribute will
1647 now only prevent relative imports in that module rather than causing
1648 all imports from that module to fail.
1649
Nick Coghlan14ff9942008-07-08 14:21:42 +00001650- Issue #2517: Allow unicode messages in Exceptions again by correctly
1651 bypassing the instance dictionary when looking up __unicode__ on
1652 new-style classes.

1655 set to a custom object whose write() method happens to install
1656 another file in sys.stdout.
1657
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001658- Issue #3088: Corrected a race condition in classes derived from
1659 threading.local: the first member set by a thread could be saved in
1660 another thread's dictionary.
1661
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001662- Issue #3004: Minor change to slice.indices(): the start and stop
1663 arguments are now treated identically, making the behaviour easier
1664 to describe and understand. For example, slice(None, -10,
1665 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1666 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1667 10, -1).
1668
Georg Brandl278fc502008-07-19 12:46:12 +00001669- Issue #3219: Calling a function with repeated keyword arguments,
1670 f(a=2, a=23), would not cause a syntax error. This was a regression
1671 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001672
Georg Brandl278fc502008-07-19 12:46:12 +00001673- Issue #2862: Make int and float freelist management consistent with
1674 other freelists. Changes their CompactFreeList apis into
1675 ClearFreeList apis and calls them via gc.collect().

1681 api functions without holding the GIL, which could lead to a fatal
1682 error when they failed.
1683
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001684- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Vinay Sajip51e65192008-07-18 09:01:10 +00001695- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001708
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001709- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1710 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001711 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001712 content-length. The problem had been corrected in the 2.4 branch, but never
1713 merged into trunk.
1714

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001728- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1729 handling is now the same as that of other special attributes like __name__).
1730
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001731- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

2185 using the 'warning's machinery in such places as the parser where
2186 use of pure Python code is not possible. Both the ``showarning()``
2187 and ``formatwarning()`` gain an optional 'line' argument which is
2188 not called by default for backwards-compatibility reasons. Setting
2189 ``warnings.showwarning()`` to an implementation that lacks support
2190 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002253- Issue #2550: The approach used by client/server code for obtaining
2254 ports to listen on in network-oriented tests has been refined in an
2255 effort to facilitate running multiple instances of the entire
2256 regression test suite in parallel without issue.
2257 test_support.bind_port() has been fixed such that it will always
2258 return a unique port -- which wasn't always the case with the
2259 previous implementation, especially if socket options had been set
2260 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2261 new implementation of bind_port() will actually raise an exception
2262 if it is passed an AF_INET/SOCK_STREAM socket with either the
2263 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2264 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2265 the socket it's been passed. This currently only applies to
2266 Windows. This option prevents any other sockets from binding to the
2267 host/port we've bound to, thus removing the possibility of the
2268 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2269 when a second SOCK_STREAM socket binds and accepts to a host/port
2270 that's already been bound by another socket. The optional preferred
2271 port parameter to bind_port() has been removed. Under no
2272 circumstances should tests be hard coding ports!
2273
2274 test_support.find_unused_port() has also been introduced, which will
2275 pass a temporary socket object to bind_port() in order to obtain an
2276 unused port. The temporary socket object is then closed and
2277 deleted, and the port is returned. This method should only be used
2278 for obtaining an unused port in order to pass to an external program
2279 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2280 a parameter to a server-oriented class that doesn't give you direct
2281 access to the underlying socket used.
2282
2283 Finally, test_support.HOST has been introduced, which should be used
2284 for the host argument of any relevant socket calls (i.e. bind and
2285 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002286
2287 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002288 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

2290 test_asynchat and test_socket_ssl.

2293 suite to run in parallel without issue.

2560-----------------
2561
Fred Drakea8ee94b2008-03-01 02:45:07 +00002562- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002563 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002565- Issue #2067: file.__exit__() now calls subclasses' close() method.
2566
2567- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002568
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002569- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002570 issue 215555 for a discussion.
2571
Eric Smitha73fbe72008-02-23 03:09:44 +00002572- Added the future_builtins module, which contains hex() and oct().
2573 These are the PEP 3127 version of these functions, designed to be
2574 compatible with the hex() and oct() builtins from Python 3.0. They
2575 differ slightly in their output formats from the existing, unchanged
2576 Python 2.6 builtins. The expected usage of the future_builtins
2577 module is:
2578 from future_builtins import hex, oct
2579
Eric Smith7ef40bf2008-02-20 23:34:22 +00002580- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2581 exponents for exponents with absolute value < 100. Follows C99
2582 standard. This is a change on Windows, which would use 3 digits.
2583 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2584 so that any alterations it does to the resulting string will be
2585 available in stringlib/formatter.h (for float.__format__).
2586
Eric Smith5a3c1352008-02-19 13:21:56 +00002587- Implemented PEP 3101, Advanced String Formatting. This adds a new
2588 builtin format(); a format() method for str and unicode; a
2589 __format__() method to object, str, unicode, int, long, float, and
2590 datetime; the class string.Formatter; and the C API
2591 PyObject_Format().
2592
Georg Brandl3ee81df2008-05-17 18:14:43 +00002593- Fixed several potential crashes, all caused by specially crafted
2594 __del__ methods exploiting objects in temporarily inconsistent
2595 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002596
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002597- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002598 prevent a possible crash: an Abstract Base Class would try to access
2599 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002600

Georg Brandl3ee81df2008-05-17 18:14:43 +00002604- Clear all free lists during a gc.collect() of the highest generation
2605 in order to allow pymalloc to free more arenas. Python may give back
2606 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002607
Georg Brandl3ee81df2008-05-17 18:14:43 +00002608- Issue #2045: Fix an infinite recursion triggered when printing a
2609 subclass of collections.defaultdict, if its default_factory is set
2610 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002611
Christian Heimesf75dbef2008-02-08 00:11:31 +00002612- Fixed a minor memory leak in dictobject.c. The content of the free
2613 list was not freed on interpreter shutdown.
2614
Georg Brandl3ee81df2008-05-17 18:14:43 +00002615- Limit free list of method and builtin function objects to 256
2616 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002617
Georg Brandl3ee81df2008-05-17 18:14:43 +00002618- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2619 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002620 to compact the internal free lists of pre-allocted ints and floats.
2621
Georg Brandl3ee81df2008-05-17 18:14:43 +00002622- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2623 calls. Python expected the return type int but the fork familie
2624 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002625
Georg Brandl3ee81df2008-05-17 18:14:43 +00002626- Issue #1678380: Fix a bug that identifies 0j and -0j when they

2636 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002637
Georg Brandl3ee81df2008-05-17 18:14:43 +00002638- Patch #1473257: generator objects gain a gi_code attribute. This is
2639 the same object as the func_code attribute of the function that
2640 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002641
Georg Brandl3ee81df2008-05-17 18:14:43 +00002642- Issue #1920: "while 0" statements were completely removed by the
2643 compiler, even in the presence of an "else" clause, which is
2644 supposed to be run when the condition is false. Now the compiler
2645 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002646
Guido van Rossumeead05f2008-01-24 18:21:02 +00002647- A few crashers fixed: weakref_in_del.py (issue #1377858);
2648 loosing_dict_ref.py (issue #1303614, test67.py);
2649 borrowed_ref_[34].py (not in tracker).
2650
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002651- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002652 suppressed while an extension is loaded by calling SetErrorMode in

2654
Georg Brandl3ee81df2008-05-17 18:14:43 +00002655- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002656 several extension methods and modules do not work without unicode
2657 support.
2658
Georg Brandl26543b12008-01-21 18:36:51 +00002659- Issue #1882: when compiling code from a string, encoding cookies in the
2660 second line of code were not always recognized correctly.
2661
Georg Brandl14404b62008-01-19 19:27:05 +00002662- Issue #1679: "0x" was taken as a valid integer literal.
2663
Georg Brandl6caad7d2008-01-26 14:19:22 +00002664- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002665 added.
2666
Christian Heimesc94e2b52008-01-14 04:13:37 +00002667- sys.float_info / PyFloat_GetInfo: The floating point information
2668 object was converted from a dict to a specialized structseq object.
2669
Georg Brandl3ee81df2008-05-17 18:14:43 +00002670- Patch #1816: Added sys.flags structseq. It exposes the status of
2671 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002672
Georg Brandl3ee81df2008-05-17 18:14:43 +00002673- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00002677- Patch #1700288: added a type attribute cache that caches method
2678 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002679
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002680- Bug #1776: __import__() no longer accepts filenames on any platform.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002689- Improve some exception messages when Windows fails to load an
2690 extension module. Now we get for example '%1 is not a valid Win32
2691 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002699 and INF. float("nan"), float("inf") and float("-inf") now work on
2700 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002702- Compiler now generates simpler and faster code for dictionary
2703 literals. The oparg for BUILD_MAP now indicates an estimated
2704 dictionary size. There is a new opcode, STORE_MAP, for adding
2705 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002734- Patch #1739468: Directories and zipfiles containing a __main__.py
2735 file can now be directly executed by passing their name to the
2736 interpreter. The directory/zipfile is automatically inserted as the
2737 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002739- Issue #1265: Fix a problem with sys.settrace, if the tracing
2740 function uses a generator expression when at the same time the
2741 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002742
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002743- sets and frozensets now have an isdisjoint() method.

2746
Neal Norwitz44f326e2007-10-05 05:29:17 +00002747- Fix warnings found by the new version of the Coverity checker.
2748
Georg Brandl3ee81df2008-05-17 18:14:43 +00002749- The enumerate() builtin function is no longer bounded to sequences
2750 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2751 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002752
Georg Brandl3ee81df2008-05-17 18:14:43 +00002753- Issue #1686386: Tuple's tp_repr did not take into account the
2754 possibility of having a self-referential tuple, which is possible
2755 from C code. Nor did object's tp_str consider that a type's tp_str
2756 could do something that could lead to an inifinite recursion.
2757 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2758 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002759
Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Issue #1164: It was possible to trigger deadlock when using the
2761 'print' statement to write to a file since the GIL was not released
2762 as needed. Now PyObject_Print() does the right thing along with
2763 various tp_print implementations of the built-in types and those in
2764 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002765
Georg Brandl3ee81df2008-05-17 18:14:43 +00002766- Issue #1147: Exceptions were directly allowing string exceptions in
2767 their throw() method even though string exceptions no longer
2768 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002769
Georg Brandl3ee81df2008-05-17 18:14:43 +00002770- Issue #1096: Prevent a segfault from getting the repr of a very
2771 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002772
Brett Cannon1e534b52007-09-07 04:18:30 +00002773- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002774 PyObject_Call() never calling back out to Python code to trigger
2775 recursion depth updates/checks. Required the creation of a static
2776 RuntimeError instance in case normalizing an exception put the
2777 recursion check value past its limit. Fixes crashers
2778 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002779

Neal Norwitz0ac60192007-05-27 04:08:54 +00002793- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002794 __*__ attributes. (Some already existed, e.g., __doc__ and
2795 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002796
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002797- Add -3 option to the interpreter to warn about features that are
2798 deprecated and will be changed/removed in Python 3.0.
2799
Georg Brandl2134e752007-05-21 20:34:16 +00002800- Patch #1686487: you can now pass any mapping after '**' in function
2801 calls.
2802
Collin Winter62903052007-05-18 23:11:24 +00002803- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002804 "except E as target:". This is to provide forwards compatibility
2805 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002806
Brett Cannon229cee22007-05-05 01:34:02 +00002807- Deprecate BaseException.message as per PEP 352.
2808
Georg Brandl3ee81df2008-05-17 18:14:43 +00002809- Issue #1303614: don't expose object's __dict__ when the dict is

2811
Vinay Sajip8549ce32007-05-06 17:53:37 +00002812- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002813 setting a plain string, ie don't expand to single letter identifiers.
2814
Raymond Hettinger13936692007-04-11 18:40:58 +00002815- Request #1191699: Slices can now be pickled.
2816
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002817- Request #1193128: str.translate() now allows a None argument for
2818 translations that only remove characters without re-mapping the
2819 remaining characters.
2820
Georg Brandl5cb76c12007-03-21 09:00:39 +00002821- Patch #1682205: a TypeError while unpacking an iterable is no longer
2822 masked by a generic one with the message "unpack non-sequence".
2823
Neal Norwitzaa754b72007-03-21 06:39:48 +00002824- Remove unused file Python/fmod.c.
2825
Guido van Rossum143b5642007-03-23 04:58:42 +00002826- Bug #1683368: The object.__init__() and object.__new__() methods are
2827 now stricter in rejecting excess arguments. The only time when
2828 either allows excess arguments is when it is not overridden and the
2829 other one is. For backwards compatibility, when both are
2830 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002831 warning later). Also, type.__init__() insists on the same signature
2832 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002833
Georg Brandl3ee81df2008-05-17 18:14:43 +00002834- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2835 object to complex using its __complex__() method before falling back
2836 to the __float__() method. Therefore, the functions in the cmath
2837 module now can operate on objects that define a __complex__()
2838 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002839
Georg Brandl3ee81df2008-05-17 18:14:43 +00002840- Patch #1623563: allow __class__ assignment for classes with
2841 __slots__. The old and the new class are still required to have the
2842 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002843
Georg Brandl3ee81df2008-05-17 18:14:43 +00002844- Patch #1642547: Fix an error/crash when encountering syntax errors

2848 ``object.__reduce_ex__()`` is called with an object that is faking
2849 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002850
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851- Patch #1680015: Don't modify __slots__ tuple if it contains an

2855
Georg Brandl7b9c5552007-03-12 14:30:05 +00002856- Bug #1678647: write a newline after printing an exception in any
2857 case, even when converting the value to a string failed.
2858
Georg Brandl871f1bc2007-03-12 13:17:36 +00002859- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002860 its argument, if it exists. If not, it will work like before. This
2861 allows customizing the output of dir() in the presence of a
2862 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002863
Collin Winter276887b2007-03-12 16:11:39 +00002864- Patch #922167: Python no longer segfaults when faced with infinitely
2865 self-recursive reload() calls (as reported by bug #742342).
2866
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867- Patch #1675981: remove unreachable code from ``type.__new__()``

2871 parthensized forms. This means complex(repr(x)) now works instead of
2872 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002873
Georg Brandlaa2321b2007-03-07 00:40:28 +00002874- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002875 makes the filenames the warning module prints much more sensible
2876 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002877
Georg Brandl49aafc92007-03-07 00:34:46 +00002878- Variant of patch #697613: don't exit the interpreter on a SystemExit
2879 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880 variable is given, but break into the interactive interpreter just
2881 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002889- Patch #1674228: when assigning a slice (old-style), check for the
2890 sq_ass_slice instead of the sq_slice slot.
2891
Georg Brandl3ee81df2008-05-17 18:14:43 +00002892- When printing an unraisable error, don't print exceptions. before
2893 the name. This duplicates the behavior whening normally printing
2894 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003427 AttributeError instead of an IOError when the server's response
3428 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003429

Georg Brandl3ee81df2008-05-17 18:14:43 +00003434- Patch #1429539: pdb now correctly initializes the __main__ module
3435 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003436 correctly now.

3444
Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Patch #1530482: add pydoc.render_doc() which returns the

3460
Georg Brandl92a6bae2007-03-13 17:43:32 +00003461- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003462 are set for invalid interpolation sequences that would lead to
3463 errors on reading back those values.

3504

3506 returned string up to the first NUL character.

3517
Georg Brandl3ee81df2008-05-17 18:14:43 +00003518- unittest now verifies more of its assumptions. In particular,
3519 TestCase and TestSuite subclasses (not instances) are no longer
3520 accepted in TestSuite.addTest(). This should cause no
3521 incompatibility since it never made sense with ordinary subclasses
3522 -- the failure just occurred later, with a more cumbersome
3523 exception.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003911- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003912 time so that opening a database previously created with the DB_DUP
3913 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3914 opens. Specifically: dictionary assignment to a DB object will
3915 replace all values for a given key when the database allows
3916 duplicate values. DB users should use DB.put(k, v) when they want
3917 to store duplicates; not DB[k] = v.

3924 characters with ASCII value less than 32. Also, it correctly quotes
3925 dots only if they occur on a single line, as opposed to the previous
3926 behavior of quoting dots if they are the second character of any
3927 line.

4273 of w# format code incorrectly truncated the length to an int, even
4274 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4275 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004305- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4306 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
