1007- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1008 returned a path longer than MAX_PATH. (But It's doubtful this code path is

1165
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001166- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1167 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1168 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1169 ``printf`` function, whereas PyString_FromFormat has an independent
1170 implementation and uses "%zd" on all platforms for size_t values.
1171 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitrou0668c622008-08-26 22:42:08 +00001192 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1193 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1195 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1196 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001332What's New in Python 2.6 beta 3?
1333================================
1334
Barry Warsaw07a4a382008-08-21 01:15:08 +00001335*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001336
1337Core and Builtins
1338-----------------
1339
Guido van Rossumf8402962008-08-20 15:01:50 +00001340- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1341 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1342 extensions do not automatically benefit from the class attribute
1343 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1344 to their tp_flags field if they care. This is a backwards
1345 compatibility feature; in 3.0, all types will use the cache by
1346 default.
1347
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001348- Keyword arguments can now follow starred arguments. (``f(a, *args,
1349 keyword=23)`` is now valid syntax.)
1350
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001351- ctypes function pointers that are COM methods have a boolean True
1352 value again.
1353
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001354- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1355 by denying s# to parse objects that have a releasebuffer procedure,
1356 and introducing s*.
1357
Georg Brandl1e13ea92008-08-11 09:07:59 +00001358- Issue #3537: Fix an assertion failure when an empty but presized dict
1359 object was stored in the freelist.
1360
Mark Dickinsonb6467572008-08-04 21:30:09 +00001361- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1362 ValueError consistently across platforms.
1363
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001364- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1365 (64bit Unix, for example), unichr() would truncate its argument and return
1366 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1367
Neal Norwitze7d8be82008-07-31 17:17:14 +00001368- Apply security patches from Apple.
1369
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001370- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1371 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1372
Antoine Pitrou92f82162008-07-25 22:22:08 +00001373- Issue #1819: function calls with several named parameters are now on
1374 average 35% faster (as measured by pybench).
1375
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001376- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1377 the python debugger steps into a class statement: the free variables (local
1378 variables defined in an outer scope) would be deleted from the outer scope.
1379
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001380- Issue #2620: Overflow checking when allocating or reallocating memory
1381 was not always being done properly in some python types and extension
1382 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1383 all been updated to perform better checks and places in the code that
1384 would previously leak memory on the error path when such an allocation
1385 failed have been fixed.

1389
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001390- Issue #3612: Added some missing basic types in ctypes.wintypes.
1391
Benjamin Petersone977ad42008-08-20 01:42:01 +00001392- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1393 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1394
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001395- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1396 version reported by these tools does not necessarily follow the python
1397 version numbering scheme, so the module is less strict when parsing it.
1398
Nick Coghlanf70385a2008-08-18 12:42:46 +00001399- Issue #2235: Added Py3k warnings for types which will become unhashable
1400 under the stricter __hash__ inheritance rules in 3.0. Several types
1401 which did not meet the rules for hash invariants and were already
1402 unhashable in 3.0 have now been explicitly flagged as unhashable in
1403 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1404 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1405
Brett Cannon88f801d2008-08-18 00:46:22 +00001406- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1407 imported into the module but exposed as part of the module's API.
1408
Brett Cannon7b96f072008-08-18 00:41:11 +00001409- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1410
Brett Cannon46225e72008-08-18 00:36:52 +00001411- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1412
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001413- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1414
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001415- Issue #3575: Incremental decoder's decode function now takes bytearray
1416 by using 's*' instead of 't#'.
1417
Jesus Cea585ad8a2009-07-02 15:37:21 +00001418- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001419 fails unicode conversion on 2nd parameter. (windows only)
1420
Facundo Batista94f243a2008-08-17 03:38:39 +00001421- Issue 2464. urllib2 now supports a malformation in the URL received
1422 in a redirect.
1423
Brett Cannonabe423e2008-08-16 21:47:07 +00001424- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001425 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001426
Facundo Batistaeb90b782008-08-16 14:44:07 +00001427- Issue #2776: fixed small issue when handling an URL with double slash
1428 after a 302 response in the case of not going through a proxy.
1429
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001430- Issue #2676: in the email package, content-type parsing was hanging on
1431 pathological input because of quadratic or exponential behaviour of a
1432 regular expression.
1433
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001434- Issue #3476: binary buffered reading through the new "io" library is now
1435 thread-safe.
1436
Brett Cannonbf3157b2008-08-14 05:00:03 +00001437- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1438 since mimetools itself is deprecated. Because modules are cached, all
1439 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1440
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001441- Issue #3134: shutil referenced undefined WindowsError symbol.
1442
Robert Schuppenies14646332008-08-10 11:01:53 +00001443- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1444 menu entries were not deleted.
1445
Brett Cannon83e81842008-08-09 23:30:55 +00001446- Copied the implementation of reduce() to _functools.reduce() to have a
1447 version that did not raise a DeprecationWarning under -3.
1448
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001449- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1450 a MemoryError rather than silently stop the iteration.
1451
Guido van Rossum59ce9012008-08-09 14:55:34 +00001452- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1453 to _sre.compile() will now be rejected. This should not affect anybody
1454 since the re.compile() function never generates invalid re-bytecode.
1455
Skip Montanaroa032bf42008-08-08 22:52:51 +00001456- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1457 upon first access it can be automatically initialized from the csv file if
1458 it wasn't initialized during instantiation.
1459
Brett Cannon3aa2a492008-08-06 22:28:09 +00001460- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1461 the reload() built-in has been removed.
1462
Brett Cannon7e30b672008-08-04 21:52:25 +00001463- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001464 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001471- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1472 raised an AttributeError.
1473
Benjamin Peterson01a24322008-07-28 23:35:27 +00001474- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001475 asking for a specific length. This problem only affected files opened
1476 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001477
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001478- Issue #3449: Update decimal module to use most recent specification
1479 (v. 1.68) and tests (v. 2.58) from IBM.
1480
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001481- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

1489
1490- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1491 invalid arguments.
1492
1493- Issue #3302: Fix several crashes when calling locale's gettext functions
1494 with None arguments.

1496- Issue #3389: Allow resolving dotted names for handlers in logging
1497 configuration files.
1498
1499- Deprecate the sunaudio module for removal in Python 3.0.
1500
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001501- Issue #3394: zipfile.writestr sets external attributes when passed a
1502 file name rather than a ZipInfo instance, so files are extracted with
1503 mode 0600 rather than 000 under Unix.
1504
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001505- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1506 argument in python 2.5, this broke code that subclassed Popen to include its
1507 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1518 interaction with the tp_hash slot (added in 2.6b2) are now documented
1519
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001520- Issue #643841: The language reference now provides more detailed
1521 coverage of the lookup process for special methods. The disclaimers
1522 regarding lack of coverage of new-style classes have also been
1523 removed, since the coverage is now fairly reasonable.

1532-----------------
1533
Georg Brandl3e483f62008-07-16 22:57:41 +00001534- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1535 its methods now allow for items objects that can be converted to
1536 an integer using operator.index().
1537
Mark Dickinson64b7e502008-07-16 09:40:03 +00001538- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1539 produced a ValueError instead of giving the correct float.
1540
Eric Smitha5fa5a22008-07-16 00:11:49 +00001541- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1542 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1543
Mark Dickinson7103aa42008-07-15 19:08:33 +00001544- Issue #3008: the float type has a new instance method 'float.hex'
1545 and a new class method 'float.fromhex' to convert floating-point
1546 numbers to and from hexadecimal strings, respectively.
1547
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001548- Issue #2235: __hash__ is once again inherited by default. To allow
1549 collections.Hashable to remain meaningful in the presence of the
1550 default hash implementation (object.__hash__), it is now possible
1551 to explicit block inheritance of hash by setting __hash__=None at
1552 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1553 level.
1554
Nick Coghlanb028f502008-07-13 14:52:36 +00001555- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1556 the parent module cannot be found while performing an absolute import.
1557 This means that an incorrectly defined __package__ attribute will
1558 now only prevent relative imports in that module rather than causing
1559 all imports from that module to fail.
1560
Nick Coghlan14ff9942008-07-08 14:21:42 +00001561- Issue #2517: Allow unicode messages in Exceptions again by correctly
1562 bypassing the instance dictionary when looking up __unicode__ on
1563 new-style classes.
1564
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001565- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

1571 another thread's dictionary.
1572
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001573- Issue #3004: Minor change to slice.indices(): the start and stop
1574 arguments are now treated identically, making the behaviour easier
1575 to describe and understand. For example, slice(None, -10,
1576 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1577 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1578 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00001580- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00002032 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002033
2034 This is controlled by the configure argument ``--with-universal-archs``:
2035

2037
2038 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2039
2040 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

Georg Brandl3ee81df2008-05-17 18:14:43 +00002094- Issue #1631171: Re-implement the 'warnings' module in C (the
2095 original Python code has been kept as backup). This will allow for
2096 using the 'warning's machinery in such places as the parser where
2097 use of pure Python code is not possible. Both the ``showarning()``
2098 and ``formatwarning()`` gain an optional 'line' argument which is
2099 not called by default for backwards-compatibility reasons. Setting
2100 ``warnings.showwarning()`` to an implementation that lacks support
2101 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002126- The getpass module has been improved on Unix. It now uses /dev/tty
2127 by default and uses stderr instead of stdout. A GetPassWarning is

2149 file.close() is called while an object is in use by another thread
2150 an IOError exception will be raised and the file will not be closed.

2154 Modules/_ctypes/libffi/configure.ac.
2155
Georg Brandl3ee81df2008-05-17 18:14:43 +00002156- Issue #2385: distutils.core.run_script() makes __file__ available,
2157 so the controlled environment will more closely mirror the typical
2158 script environment. This supports setup.py scripts that refer to
2159 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002164- Issue #2550: The approach used by client/server code for obtaining
2165 ports to listen on in network-oriented tests has been refined in an
2166 effort to facilitate running multiple instances of the entire
2167 regression test suite in parallel without issue.
2168 test_support.bind_port() has been fixed such that it will always
2169 return a unique port -- which wasn't always the case with the
2170 previous implementation, especially if socket options had been set
2171 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2172 new implementation of bind_port() will actually raise an exception
2173 if it is passed an AF_INET/SOCK_STREAM socket with either the
2174 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2175 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2176 the socket it's been passed. This currently only applies to
2177 Windows. This option prevents any other sockets from binding to the
2178 host/port we've bound to, thus removing the possibility of the
2179 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2180 when a second SOCK_STREAM socket binds and accepts to a host/port
2181 that's already been bound by another socket. The optional preferred
2182 port parameter to bind_port() has been removed. Under no
2183 circumstances should tests be hard coding ports!
2184
2185 test_support.find_unused_port() has also been introduced, which will
2186 pass a temporary socket object to bind_port() in order to obtain an
2187 unused port. The temporary socket object is then closed and
2188 deleted, and the port is returned. This method should only be used
2189 for obtaining an unused port in order to pass to an external program
2190 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2191 a parameter to a server-oriented class that doesn't give you direct
2192 access to the underlying socket used.
2193
2194 Finally, test_support.HOST has been introduced, which should be used
2195 for the host argument of any relevant socket calls (i.e. bind and
2196 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002197
2198 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002199 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002200 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2201 test_asynchat and test_socket_ssl.
2202
Georg Brandl3ee81df2008-05-17 18:14:43 +00002203 It is now possible for multiple instances of the regression test
2204 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00002408- The bundled libffi copy is now in sync with the recently released
2409 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002410 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2411 files are used. On all linux systems the --with-system-ffi
2412 configure option defaults to "yes".

2472
Fred Drakea8ee94b2008-03-01 02:45:07 +00002473- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002474 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002476- Issue #2067: file.__exit__() now calls subclasses' close() method.
2477
2478- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002479
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002480- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002481 issue 215555 for a discussion.
2482
Eric Smitha73fbe72008-02-23 03:09:44 +00002483- Added the future_builtins module, which contains hex() and oct().
2484 These are the PEP 3127 version of these functions, designed to be
2485 compatible with the hex() and oct() builtins from Python 3.0. They
2486 differ slightly in their output formats from the existing, unchanged
2487 Python 2.6 builtins. The expected usage of the future_builtins
2488 module is:
2489 from future_builtins import hex, oct
2490
Eric Smith7ef40bf2008-02-20 23:34:22 +00002491- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2492 exponents for exponents with absolute value < 100. Follows C99
2493 standard. This is a change on Windows, which would use 3 digits.
2494 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2495 so that any alterations it does to the resulting string will be
2496 available in stringlib/formatter.h (for float.__format__).
2497
Eric Smith5a3c1352008-02-19 13:21:56 +00002498- Implemented PEP 3101, Advanced String Formatting. This adds a new
2499 builtin format(); a format() method for str and unicode; a
2500 __format__() method to object, str, unicode, int, long, float, and
2501 datetime; the class string.Formatter; and the C API
2502 PyObject_Format().
2503
Georg Brandl3ee81df2008-05-17 18:14:43 +00002504- Fixed several potential crashes, all caused by specially crafted
2505 __del__ methods exploiting objects in temporarily inconsistent
2506 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002507
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002508- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002509 prevent a possible crash: an Abstract Base Class would try to access
2510 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002511
Georg Brandl3ee81df2008-05-17 18:14:43 +00002512- Fixed repr() and str() of complex numbers with infinity or nan as
2513 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002514
Georg Brandl3ee81df2008-05-17 18:14:43 +00002515- Clear all free lists during a gc.collect() of the highest generation
2516 in order to allow pymalloc to free more arenas. Python may give back
2517 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002518
Georg Brandl3ee81df2008-05-17 18:14:43 +00002519- Issue #2045: Fix an infinite recursion triggered when printing a
2520 subclass of collections.defaultdict, if its default_factory is set
2521 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002522
Christian Heimesf75dbef2008-02-08 00:11:31 +00002523- Fixed a minor memory leak in dictobject.c. The content of the free
2524 list was not freed on interpreter shutdown.
2525
Georg Brandl3ee81df2008-05-17 18:14:43 +00002526- Limit free list of method and builtin function objects to 256
2527 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002528
Georg Brandl3ee81df2008-05-17 18:14:43 +00002529- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2530 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002531 to compact the internal free lists of pre-allocted ints and floats.
2532
Georg Brandl3ee81df2008-05-17 18:14:43 +00002533- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2534 calls. Python expected the return type int but the fork familie
2535 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002536
Georg Brandl3ee81df2008-05-17 18:14:43 +00002537- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2538 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002539

2547 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002548
Georg Brandl3ee81df2008-05-17 18:14:43 +00002549- Patch #1473257: generator objects gain a gi_code attribute. This is
2550 the same object as the func_code attribute of the function that
2551 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002552
Georg Brandl3ee81df2008-05-17 18:14:43 +00002553- Issue #1920: "while 0" statements were completely removed by the
2554 compiler, even in the presence of an "else" clause, which is
2555 supposed to be run when the condition is false. Now the compiler
2556 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002557
Guido van Rossumeead05f2008-01-24 18:21:02 +00002558- A few crashers fixed: weakref_in_del.py (issue #1377858);
2559 loosing_dict_ref.py (issue #1303614, test67.py);
2560 borrowed_ref_[34].py (not in tracker).
2561
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002562- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002563 suppressed while an extension is loaded by calling SetErrorMode in
2564 dynload_win.c. The error is still reported properly.
2565
Georg Brandl3ee81df2008-05-17 18:14:43 +00002566- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002567 several extension methods and modules do not work without unicode
2568 support.
2569
Georg Brandl26543b12008-01-21 18:36:51 +00002570- Issue #1882: when compiling code from a string, encoding cookies in the
2571 second line of code were not always recognized correctly.
2572
Georg Brandl14404b62008-01-19 19:27:05 +00002573- Issue #1679: "0x" was taken as a valid integer literal.
2574
Georg Brandl6caad7d2008-01-26 14:19:22 +00002575- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002576 added.
2577
Christian Heimesc94e2b52008-01-14 04:13:37 +00002578- sys.float_info / PyFloat_GetInfo: The floating point information
2579 object was converted from a dict to a specialized structseq object.
2580
Georg Brandl3ee81df2008-05-17 18:14:43 +00002581- Patch #1816: Added sys.flags structseq. It exposes the status of
2582 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002583
Georg Brandl3ee81df2008-05-17 18:14:43 +00002584- Objects/structseq.c: Implemented new structseq representation. The
2585 patch makes structseqs (e.g. the return value of os.stat) more
2586 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002587
Georg Brandl3ee81df2008-05-17 18:14:43 +00002588- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002610 and INF. float("nan"), float("inf") and float("-inf") now work on
2611 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002612
Georg Brandl3ee81df2008-05-17 18:14:43 +00002613- Compiler now generates simpler and faster code for dictionary
2614 literals. The oparg for BUILD_MAP now indicates an estimated
2615 dictionary size. There is a new opcode, STORE_MAP, for adding
2616 entries to the dictionary.

Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002654- sets and frozensets now have an isdisjoint() method.
2655
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002656- optimize the performance of builtin.sum().
2657
Neal Norwitz44f326e2007-10-05 05:29:17 +00002658- Fix warnings found by the new version of the Coverity checker.
2659
Georg Brandl3ee81df2008-05-17 18:14:43 +00002660- The enumerate() builtin function is no longer bounded to sequences
2661 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2662 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002663
Georg Brandl3ee81df2008-05-17 18:14:43 +00002664- Issue #1686386: Tuple's tp_repr did not take into account the
2665 possibility of having a self-referential tuple, which is possible
2666 from C code. Nor did object's tp_str consider that a type's tp_str
2667 could do something that could lead to an inifinite recursion.
2668 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2669 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002670
Georg Brandl3ee81df2008-05-17 18:14:43 +00002671- Issue #1164: It was possible to trigger deadlock when using the
2672 'print' statement to write to a file since the GIL was not released
2673 as needed. Now PyObject_Print() does the right thing along with
2674 various tp_print implementations of the built-in types and those in
2675 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002676
Georg Brandl3ee81df2008-05-17 18:14:43 +00002677- Issue #1147: Exceptions were directly allowing string exceptions in
2678 their throw() method even though string exceptions no longer
2679 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002680
Georg Brandl3ee81df2008-05-17 18:14:43 +00002681- Issue #1096: Prevent a segfault from getting the repr of a very
2682 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002683
Brett Cannon1e534b52007-09-07 04:18:30 +00002684- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002685 PyObject_Call() never calling back out to Python code to trigger
2686 recursion depth updates/checks. Required the creation of a static
2687 RuntimeError instance in case normalizing an exception put the
2688 recursion check value past its limit. Fixes crashers
2689 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002690
Georg Brandl3ee81df2008-05-17 18:14:43 +00002691- Patch #1031213: Decode source line in SyntaxErrors back to its

2695 with %G.
2696
Georg Brandl3ee81df2008-05-17 18:14:43 +00002697- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00002704- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002705 __*__ attributes. (Some already existed, e.g., __doc__ and
2706 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002707
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002708- Add -3 option to the interpreter to warn about features that are
2709 deprecated and will be changed/removed in Python 3.0.
2710
Georg Brandl2134e752007-05-21 20:34:16 +00002711- Patch #1686487: you can now pass any mapping after '**' in function
2712 calls.
2713
Collin Winter62903052007-05-18 23:11:24 +00002714- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002715 "except E as target:". This is to provide forwards compatibility
2716 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002717
Brett Cannon229cee22007-05-05 01:34:02 +00002718- Deprecate BaseException.message as per PEP 352.
2719
Georg Brandl3ee81df2008-05-17 18:14:43 +00002720- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002721 inherited from a builtin base.
2722
Vinay Sajip8549ce32007-05-06 17:53:37 +00002723- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002724 setting a plain string, ie don't expand to single letter identifiers.
2725
Raymond Hettinger13936692007-04-11 18:40:58 +00002726- Request #1191699: Slices can now be pickled.
2727
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002728- Request #1193128: str.translate() now allows a None argument for
2729 translations that only remove characters without re-mapping the
2730 remaining characters.
2731
Georg Brandl5cb76c12007-03-21 09:00:39 +00002732- Patch #1682205: a TypeError while unpacking an iterable is no longer
2733 masked by a generic one with the message "unpack non-sequence".
2734
Neal Norwitzaa754b72007-03-21 06:39:48 +00002735- Remove unused file Python/fmod.c.
2736
Guido van Rossum143b5642007-03-23 04:58:42 +00002737- Bug #1683368: The object.__init__() and object.__new__() methods are
2738 now stricter in rejecting excess arguments. The only time when
2739 either allows excess arguments is when it is not overridden and the
2740 other one is. For backwards compatibility, when both are
2741 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002742 warning later). Also, type.__init__() insists on the same signature
2743 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002744
Georg Brandl3ee81df2008-05-17 18:14:43 +00002745- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2746 object to complex using its __complex__() method before falling back
2747 to the __float__() method. Therefore, the functions in the cmath
2748 module now can operate on objects that define a __complex__()
2749 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002750
Georg Brandl3ee81df2008-05-17 18:14:43 +00002751- Patch #1623563: allow __class__ assignment for classes with
2752 __slots__. The old and the new class are still required to have the
2753 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002754
Georg Brandl3ee81df2008-05-17 18:14:43 +00002755- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002758- Patch #1462488: Python no longer segfaults when
2759 ``object.__reduce_ex__()`` is called with an object that is faking
2760 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002761
Georg Brandl3ee81df2008-05-17 18:14:43 +00002762- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002765- Patch #1444529: the builtin compile() now accepts keyword arguments.
2766
Georg Brandl7b9c5552007-03-12 14:30:05 +00002767- Bug #1678647: write a newline after printing an exception in any
2768 case, even when converting the value to a string failed.
2769
Georg Brandl871f1bc2007-03-12 13:17:36 +00002770- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002771 its argument, if it exists. If not, it will work like before. This
2772 allows customizing the output of dir() in the presence of a
2773 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002774
Collin Winter276887b2007-03-12 16:11:39 +00002775- Patch #922167: Python no longer segfaults when faced with infinitely
2776 self-recursive reload() calls (as reported by bug #742342).
2777
Georg Brandl3ee81df2008-05-17 18:14:43 +00002778- Patch #1675981: remove unreachable code from ``type.__new__()``
2779 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002781- Patch #1491866: change the complex() constructor to allow
2782 parthensized forms. This means complex(repr(x)) now works instead of
2783 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002784
Georg Brandlaa2321b2007-03-07 00:40:28 +00002785- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002786 makes the filenames the warning module prints much more sensible
2787 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002788
Georg Brandl49aafc92007-03-07 00:34:46 +00002789- Variant of patch #697613: don't exit the interpreter on a SystemExit
2790 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002791 variable is given, but break into the interactive interpreter just
2792 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00002799
Georg Brandl0fca97a2007-03-05 22:28:08 +00002800- Patch #1674228: when assigning a slice (old-style), check for the
2801 sq_ass_slice instead of the sq_slice slot.
2802
Georg Brandl3ee81df2008-05-17 18:14:43 +00002803- When printing an unraisable error, don't print exceptions. before
2804 the name. This duplicates the behavior whening normally printing
2805 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002806
Georg Brandl3ee81df2008-05-17 18:14:43 +00002807- Bug #1653736: Properly discard third argument to

2814 created a weakref on itself during a __del__ call for new-style
2815 classes (classic classes still have the bug).

2862
Armin Rigo7ccbca92006-10-04 12:17:45 +00002863- A number of places, including integer negation and absolute value,
2864 were fixed to not rely on undefined behaviour of the C compiler
2865 anymore.

2869
Georg Brandl5d59c092006-09-30 08:43:30 +00002870- Patch #1567691: super() and new.instancemethod() now don't accept

3434 exception.

3648
Georg Brandl3ee81df2008-05-17 18:14:43 +00003649- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003715- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3716 with RFC 3207 and forgets any knowledge obtained from the server not
3717 obtained from the TLS negotiation itself. Patch contributed by Bill
3718 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003719
Georg Brandl3ee81df2008-05-17 18:14:43 +00003720- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003721 that the SMTP.starttls() caller no longer needs to call ehlo()
3722 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003723 does not claim to support starttls. Adds the
3724 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3725 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003779- itertools.chain() now has an alternate constructor,

3794 contents before adding elements from the iterable. This fix brings
3795 the behavior into line with that for list.__init__().

3805 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3806 silently miscode subclasses of those types. Now, it raises a
3807 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003808

Georg Brandl3ee81df2008-05-17 18:14:43 +00003823 time so that opening a database previously created with the DB_DUP
3824 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3825 opens. Specifically: dictionary assignment to a DB object will
3826 replace all values for a given key when the database allows
3827 duplicate values. DB users should use DB.put(k, v) when they want
3828 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003829

3835 characters with ASCII value less than 32. Also, it correctly quotes
3836 dots only if they occur on a single line, as opposed to the previous
3837 behavior of quoting dots if they are the second character of any
3838 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003839

Georg Brandldb846032007-03-31 18:56:11 +00004125- Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS
4126 returned by python-config if Python was built with --enable-shared
4127 because that prevented the shared library from being used.
4128

4161-----
4162
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163- Unified naming convention for free lists and their limits. All free
4164 lists in Object/ are named ``free_list``, the counter ``numfree``
4165 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4166 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004167
Georg Brandl3ee81df2008-05-17 18:14:43 +00004168- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4169 to ``PyTuple_SetItem``, it can be used to populate a brand new
4170 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004171
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004172- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

4175 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4176 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004177
4178- Patch #1720595: add T_BOOL to the range of structmember types.
4179
4180- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4181 ``PyFloat_GetInfo()`` to the float API.
4182
Georg Brandl3ee81df2008-05-17 18:14:43 +00004183- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4184 of w# format code incorrectly truncated the length to an int, even
4185 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4186 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004187
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4189 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004191- PEP 3123: Provide forward compatibility with Python 3.0, while
4192 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4193 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004194
Georg Brandl3ee81df2008-05-17 18:14:43 +00004195- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4196 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004197
4198- Patch #1733960: Allow T_LONGLONG to accept ints.

4205
4206- Fix some leftovers from the conversion from int to Py_ssize_t
4207 (relevant to strings and sequences of more than 2**31 items).
4208
4209- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4210 outside of pystate.c and should not be necessary.
4211
Georg Brandl3ee81df2008-05-17 18:14:43 +00004212- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4213 absolute imports. In earlier versions they might have used relative
4214 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004215
Georg Brandl3ee81df2008-05-17 18:14:43 +00004216- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4217 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004218
Georg Brandl3ee81df2008-05-17 18:14:43 +00004219- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004226- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4227 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4228 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4229 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004230

Georg Brandl3ee81df2008-05-17 18:14:43 +00004244- Removed the macfs module. It had been deprecated since Python 2.5.
4245 This lead to the deprecation of macostools.touched() as it relied
4246 solely on macfs and was a no-op under OS X.
