1009- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1010 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1011 really executed because I cannot move to such directory on win2k)

1167
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001168- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1169 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1170 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1171 ``printf`` function, whereas PyString_FromFormat has an independent
1172 implementation and uses "%zd" on all platforms for size_t values.
1173 This makes a difference on win64, where ``printf`` needs "%Id" to display
1174 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001194 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1195 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1197 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1198 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001334What's New in Python 2.6 beta 3?
1335================================
1336
Barry Warsaw07a4a382008-08-21 01:15:08 +00001337*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001338
1339Core and Builtins
1340-----------------
1341
Guido van Rossumf8402962008-08-20 15:01:50 +00001342- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1343 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1344 extensions do not automatically benefit from the class attribute
1345 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1346 to their tp_flags field if they care. This is a backwards
1347 compatibility feature; in 3.0, all types will use the cache by
1348 default.
1349
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001350- Keyword arguments can now follow starred arguments. (``f(a, *args,
1351 keyword=23)`` is now valid syntax.)
1352
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001353- ctypes function pointers that are COM methods have a boolean True
1354 value again.
1355
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001356- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1357 by denying s# to parse objects that have a releasebuffer procedure,
1358 and introducing s*.
1359
Georg Brandl1e13ea92008-08-11 09:07:59 +00001360- Issue #3537: Fix an assertion failure when an empty but presized dict
1361 object was stored in the freelist.
1362
Mark Dickinsonb6467572008-08-04 21:30:09 +00001363- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1364 ValueError consistently across platforms.
1365
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001366- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1367 (64bit Unix, for example), unichr() would truncate its argument and return
1368 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1369
Neal Norwitze7d8be82008-07-31 17:17:14 +00001370- Apply security patches from Apple.
1371
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001372- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1373 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1374
Antoine Pitrou92f82162008-07-25 22:22:08 +00001375- Issue #1819: function calls with several named parameters are now on
1376 average 35% faster (as measured by pybench).
1377
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001378- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1379 the python debugger steps into a class statement: the free variables (local
1380 variables defined in an outer scope) would be deleted from the outer scope.
1381
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001382- Issue #2620: Overflow checking when allocating or reallocating memory
1383 was not always being done properly in some python types and extension
1384 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1385 all been updated to perform better checks and places in the code that
1386 would previously leak memory on the error path when such an allocation
1387 failed have been fixed.
1388
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001389Library
1390-------
1391
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001392- Issue #3612: Added some missing basic types in ctypes.wintypes.
1393
Benjamin Petersone977ad42008-08-20 01:42:01 +00001394- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1395 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1396
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001397- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1398 version reported by these tools does not necessarily follow the python
1399 version numbering scheme, so the module is less strict when parsing it.
1400
Nick Coghlanf70385a2008-08-18 12:42:46 +00001401- Issue #2235: Added Py3k warnings for types which will become unhashable
1402 under the stricter __hash__ inheritance rules in 3.0. Several types
1403 which did not meet the rules for hash invariants and were already
1404 unhashable in 3.0 have now been explicitly flagged as unhashable in
1405 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1406 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1407
Brett Cannon88f801d2008-08-18 00:46:22 +00001408- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1409 imported into the module but exposed as part of the module's API.
1410
Brett Cannon7b96f072008-08-18 00:41:11 +00001411- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1412
Brett Cannon46225e72008-08-18 00:36:52 +00001413- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1414
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001415- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1416
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001417- Issue #3575: Incremental decoder's decode function now takes bytearray
1418 by using 's*' instead of 't#'.
1419
Jesus Cea585ad8a2009-07-02 15:37:21 +00001420- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001421 fails unicode conversion on 2nd parameter. (windows only)
1422
Facundo Batista94f243a2008-08-17 03:38:39 +00001423- Issue 2464. urllib2 now supports a malformation in the URL received
1424 in a redirect.
1425
Brett Cannonabe423e2008-08-16 21:47:07 +00001426- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001427 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001428
Facundo Batistaeb90b782008-08-16 14:44:07 +00001429- Issue #2776: fixed small issue when handling an URL with double slash
1430 after a 302 response in the case of not going through a proxy.
1431
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001432- Issue #2676: in the email package, content-type parsing was hanging on
1433 pathological input because of quadratic or exponential behaviour of a
1434 regular expression.
1435
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001436- Issue #3476: binary buffered reading through the new "io" library is now
1437 thread-safe.
1438
Brett Cannonbf3157b2008-08-14 05:00:03 +00001439- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1440 since mimetools itself is deprecated. Because modules are cached, all
1441 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1442
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001443- Issue #3134: shutil referenced undefined WindowsError symbol.
1444
Robert Schuppenies14646332008-08-10 11:01:53 +00001445- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1446 menu entries were not deleted.
1447
Brett Cannon83e81842008-08-09 23:30:55 +00001448- Copied the implementation of reduce() to _functools.reduce() to have a
1449 version that did not raise a DeprecationWarning under -3.
1450
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001451- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1452 a MemoryError rather than silently stop the iteration.
1453
Guido van Rossum59ce9012008-08-09 14:55:34 +00001454- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1455 to _sre.compile() will now be rejected. This should not affect anybody
1456 since the re.compile() function never generates invalid re-bytecode.
1457
Skip Montanaroa032bf42008-08-08 22:52:51 +00001458- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1459 upon first access it can be automatically initialized from the csv file if
1460 it wasn't initialized during instantiation.
1461
Brett Cannon3aa2a492008-08-06 22:28:09 +00001462- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1463 the reload() built-in has been removed.
1464
Brett Cannon7e30b672008-08-04 21:52:25 +00001465- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001466 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001473- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1474 raised an AttributeError.
1475
Benjamin Peterson01a24322008-07-28 23:35:27 +00001476- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001477 asking for a specific length. This problem only affected files opened
1478 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001479
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001480- Issue #3449: Update decimal module to use most recent specification
1481 (v. 1.68) and tests (v. 2.58) from IBM.
1482
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001483- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1484

1491
1492- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1493 invalid arguments.
1494
1495- Issue #3302: Fix several crashes when calling locale's gettext functions
1496 with None arguments.
1497
1498- Issue #3389: Allow resolving dotted names for handlers in logging
1499 configuration files.
1500
1501- Deprecate the sunaudio module for removal in Python 3.0.
1502
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001503- Issue #3394: zipfile.writestr sets external attributes when passed a
1504 file name rather than a ZipInfo instance, so files are extracted with
1505 mode 0600 rather than 000 under Unix.
1506
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001507- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1508 argument in python 2.5, this broke code that subclassed Popen to include its
1509 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001519- Issue #2235: the C API function PyObject_HashNotImplemented and its
1520 interaction with the tp_hash slot (added in 2.6b2) are now documented
1521
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001522- Issue #643841: The language reference now provides more detailed
1523 coverage of the lookup process for special methods. The disclaimers
1524 regarding lack of coverage of new-style classes have also been
1525 removed, since the coverage is now fairly reasonable.

1530
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001531*Release date: 17-Jul-2008*

1534-----------------
1535
Georg Brandl3e483f62008-07-16 22:57:41 +00001536- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1537 its methods now allow for items objects that can be converted to
1538 an integer using operator.index().
1539
Mark Dickinson64b7e502008-07-16 09:40:03 +00001540- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1541 produced a ValueError instead of giving the correct float.
1542
Eric Smitha5fa5a22008-07-16 00:11:49 +00001543- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1544 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1545
Mark Dickinson7103aa42008-07-15 19:08:33 +00001546- Issue #3008: the float type has a new instance method 'float.hex'
1547 and a new class method 'float.fromhex' to convert floating-point
1548 numbers to and from hexadecimal strings, respectively.
1549
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001550- Issue #2235: __hash__ is once again inherited by default. To allow
1551 collections.Hashable to remain meaningful in the presence of the
1552 default hash implementation (object.__hash__), it is now possible
1553 to explicit block inheritance of hash by setting __hash__=None at
1554 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1555 level.
1556
Nick Coghlanb028f502008-07-13 14:52:36 +00001557- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1558 the parent module cannot be found while performing an absolute import.
1559 This means that an incorrectly defined __package__ attribute will
1560 now only prevent relative imports in that module rather than causing
1561 all imports from that module to fail.
1562
Nick Coghlan14ff9942008-07-08 14:21:42 +00001563- Issue #2517: Allow unicode messages in Exceptions again by correctly
1564 bypassing the instance dictionary when looking up __unicode__ on
1565 new-style classes.
1566
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001567- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1568 set to a custom object whose write() method happens to install
1569 another file in sys.stdout.

1573 another thread's dictionary.
1574
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001575- Issue #3004: Minor change to slice.indices(): the start and stop
1576 arguments are now treated identically, making the behaviour easier
1577 to describe and understand. For example, slice(None, -10,
1578 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1579 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1580 10, -1).
1581
Georg Brandl278fc502008-07-19 12:46:12 +00001582- Issue #3219: Calling a function with repeated keyword arguments,

1584 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002034 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002035
2036 This is controlled by the configure argument ``--with-universal-archs``:
2037

2039
2040 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2041
2042 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

Georg Brandl3ee81df2008-05-17 18:14:43 +00002096- Issue #1631171: Re-implement the 'warnings' module in C (the
2097 original Python code has been kept as backup). This will allow for
2098 using the 'warning's machinery in such places as the parser where
2099 use of pure Python code is not possible. Both the ``showarning()``
2100 and ``formatwarning()`` gain an optional 'line' argument which is
2101 not called by default for backwards-compatibility reasons. Setting
2102 ``warnings.showwarning()`` to an implementation that lacks support
2103 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002128- The getpass module has been improved on Unix. It now uses /dev/tty
2129 by default and uses stderr instead of stdout. A GetPassWarning is

Gregory P. Smithaa63d0d2008-04-06 23:11:17 +00002149- Issue #815646: Individual file objects may now be used from multiple
2150 threads at once without fear of crashing the Python interpreter. If
2151 file.close() is called while an object is in use by another thread
2152 an IOError exception will be raised and the file will not be closed.

2156 Modules/_ctypes/libffi/configure.ac.
2157
Georg Brandl3ee81df2008-05-17 18:14:43 +00002158- Issue #2385: distutils.core.run_script() makes __file__ available,
2159 so the controlled environment will more closely mirror the typical
2160 script environment. This supports setup.py scripts that refer to
2161 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002166- Issue #2550: The approach used by client/server code for obtaining
2167 ports to listen on in network-oriented tests has been refined in an
2168 effort to facilitate running multiple instances of the entire
2169 regression test suite in parallel without issue.
2170 test_support.bind_port() has been fixed such that it will always
2171 return a unique port -- which wasn't always the case with the
2172 previous implementation, especially if socket options had been set
2173 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2174 new implementation of bind_port() will actually raise an exception
2175 if it is passed an AF_INET/SOCK_STREAM socket with either the
2176 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2177 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2178 the socket it's been passed. This currently only applies to
2179 Windows. This option prevents any other sockets from binding to the
2180 host/port we've bound to, thus removing the possibility of the
2181 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2182 when a second SOCK_STREAM socket binds and accepts to a host/port
2183 that's already been bound by another socket. The optional preferred
2184 port parameter to bind_port() has been removed. Under no
2185 circumstances should tests be hard coding ports!
2186
2187 test_support.find_unused_port() has also been introduced, which will
2188 pass a temporary socket object to bind_port() in order to obtain an
2189 unused port. The temporary socket object is then closed and
2190 deleted, and the port is returned. This method should only be used
2191 for obtaining an unused port in order to pass to an external program
2192 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2193 a parameter to a server-oriented class that doesn't give you direct
2194 access to the underlying socket used.
2195
2196 Finally, test_support.HOST has been introduced, which should be used
2197 for the host argument of any relevant socket calls (i.e. bind and
2198 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002199
2200 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002201 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002202 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2203 test_asynchat and test_socket_ssl.
2204
Georg Brandl3ee81df2008-05-17 18:14:43 +00002205 It is now possible for multiple instances of the regression test
2206 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00002410- The bundled libffi copy is now in sync with the recently released
2411 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002412 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2413 files are used. On all linux systems the --with-system-ffi
2414 configure option defaults to "yes".

2473-----------------
2474
Fred Drakea8ee94b2008-03-01 02:45:07 +00002475- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002476 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002478- Issue #2067: file.__exit__() now calls subclasses' close() method.
2479
2480- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002481
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002482- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002483 issue 215555 for a discussion.
2484
Eric Smitha73fbe72008-02-23 03:09:44 +00002485- Added the future_builtins module, which contains hex() and oct().
2486 These are the PEP 3127 version of these functions, designed to be
2487 compatible with the hex() and oct() builtins from Python 3.0. They
2488 differ slightly in their output formats from the existing, unchanged
2489 Python 2.6 builtins. The expected usage of the future_builtins
2490 module is:
2491 from future_builtins import hex, oct
2492
Eric Smith7ef40bf2008-02-20 23:34:22 +00002493- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2494 exponents for exponents with absolute value < 100. Follows C99
2495 standard. This is a change on Windows, which would use 3 digits.
2496 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2497 so that any alterations it does to the resulting string will be
2498 available in stringlib/formatter.h (for float.__format__).
2499
Eric Smith5a3c1352008-02-19 13:21:56 +00002500- Implemented PEP 3101, Advanced String Formatting. This adds a new
2501 builtin format(); a format() method for str and unicode; a
2502 __format__() method to object, str, unicode, int, long, float, and
2503 datetime; the class string.Formatter; and the C API
2504 PyObject_Format().
2505
Georg Brandl3ee81df2008-05-17 18:14:43 +00002506- Fixed several potential crashes, all caused by specially crafted
2507 __del__ methods exploiting objects in temporarily inconsistent
2508 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002509
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002510- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002511 prevent a possible crash: an Abstract Base Class would try to access
2512 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002513
Georg Brandl3ee81df2008-05-17 18:14:43 +00002514- Fixed repr() and str() of complex numbers with infinity or nan as
2515 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002516
Georg Brandl3ee81df2008-05-17 18:14:43 +00002517- Clear all free lists during a gc.collect() of the highest generation
2518 in order to allow pymalloc to free more arenas. Python may give back
2519 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002520
Georg Brandl3ee81df2008-05-17 18:14:43 +00002521- Issue #2045: Fix an infinite recursion triggered when printing a
2522 subclass of collections.defaultdict, if its default_factory is set
2523 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002524
Christian Heimesf75dbef2008-02-08 00:11:31 +00002525- Fixed a minor memory leak in dictobject.c. The content of the free
2526 list was not freed on interpreter shutdown.
2527
Georg Brandl3ee81df2008-05-17 18:14:43 +00002528- Limit free list of method and builtin function objects to 256
2529 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002530
Georg Brandl3ee81df2008-05-17 18:14:43 +00002531- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2532 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002533 to compact the internal free lists of pre-allocted ints and floats.
2534
Georg Brandl3ee81df2008-05-17 18:14:43 +00002535- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2536 calls. Python expected the return type int but the fork familie
2537 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002538
Georg Brandl3ee81df2008-05-17 18:14:43 +00002539- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2540 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002541

2549 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002550
Georg Brandl3ee81df2008-05-17 18:14:43 +00002551- Patch #1473257: generator objects gain a gi_code attribute. This is
2552 the same object as the func_code attribute of the function that
2553 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002554
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555- Issue #1920: "while 0" statements were completely removed by the
2556 compiler, even in the presence of an "else" clause, which is
2557 supposed to be run when the condition is false. Now the compiler
2558 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002559
Guido van Rossumeead05f2008-01-24 18:21:02 +00002560- A few crashers fixed: weakref_in_del.py (issue #1377858);
2561 loosing_dict_ref.py (issue #1303614, test67.py);
2562 borrowed_ref_[34].py (not in tracker).
2563
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002564- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002565 suppressed while an extension is loaded by calling SetErrorMode in
2566 dynload_win.c. The error is still reported properly.
2567
Georg Brandl3ee81df2008-05-17 18:14:43 +00002568- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002569 several extension methods and modules do not work without unicode
2570 support.
2571
Georg Brandl26543b12008-01-21 18:36:51 +00002572- Issue #1882: when compiling code from a string, encoding cookies in the
2573 second line of code were not always recognized correctly.
2574
Georg Brandl14404b62008-01-19 19:27:05 +00002575- Issue #1679: "0x" was taken as a valid integer literal.
2576
Georg Brandl6caad7d2008-01-26 14:19:22 +00002577- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002578 added.
2579
Christian Heimesc94e2b52008-01-14 04:13:37 +00002580- sys.float_info / PyFloat_GetInfo: The floating point information
2581 object was converted from a dict to a specialized structseq object.
2582
Georg Brandl3ee81df2008-05-17 18:14:43 +00002583- Patch #1816: Added sys.flags structseq. It exposes the status of
2584 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002585
Georg Brandl3ee81df2008-05-17 18:14:43 +00002586- Objects/structseq.c: Implemented new structseq representation. The
2587 patch makes structseqs (e.g. the return value of os.stat) more
2588 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002589
Georg Brandl3ee81df2008-05-17 18:14:43 +00002590- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002612 and INF. float("nan"), float("inf") and float("-inf") now work on
2613 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002614
Georg Brandl3ee81df2008-05-17 18:14:43 +00002615- Compiler now generates simpler and faster code for dictionary
2616 literals. The oparg for BUILD_MAP now indicates an estimated
2617 dictionary size. There is a new opcode, STORE_MAP, for adding
2618 entries to the dictionary.

Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002656- sets and frozensets now have an isdisjoint() method.
2657
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002658- optimize the performance of builtin.sum().
2659
Neal Norwitz44f326e2007-10-05 05:29:17 +00002660- Fix warnings found by the new version of the Coverity checker.
2661
Georg Brandl3ee81df2008-05-17 18:14:43 +00002662- The enumerate() builtin function is no longer bounded to sequences
2663 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2664 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002665
Georg Brandl3ee81df2008-05-17 18:14:43 +00002666- Issue #1686386: Tuple's tp_repr did not take into account the
2667 possibility of having a self-referential tuple, which is possible
2668 from C code. Nor did object's tp_str consider that a type's tp_str
2669 could do something that could lead to an inifinite recursion.
2670 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2671 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002672
Georg Brandl3ee81df2008-05-17 18:14:43 +00002673- Issue #1164: It was possible to trigger deadlock when using the
2674 'print' statement to write to a file since the GIL was not released
2675 as needed. Now PyObject_Print() does the right thing along with
2676 various tp_print implementations of the built-in types and those in
2677 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002678
Georg Brandl3ee81df2008-05-17 18:14:43 +00002679- Issue #1147: Exceptions were directly allowing string exceptions in
2680 their throw() method even though string exceptions no longer
2681 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002682
Georg Brandl3ee81df2008-05-17 18:14:43 +00002683- Issue #1096: Prevent a segfault from getting the repr of a very
2684 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002685
Brett Cannon1e534b52007-09-07 04:18:30 +00002686- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002687 PyObject_Call() never calling back out to Python code to trigger
2688 recursion depth updates/checks. Required the creation of a static
2689 RuntimeError instance in case normalizing an exception put the
2690 recursion check value past its limit. Fixes crashers
2691 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002692
Georg Brandl3ee81df2008-05-17 18:14:43 +00002693- Patch #1031213: Decode source line in SyntaxErrors back to its

2697 with %G.
2698
Georg Brandl3ee81df2008-05-17 18:14:43 +00002699- Prevent expandtabs() on string and unicode objects from causing a
2700 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002706- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002707 __*__ attributes. (Some already existed, e.g., __doc__ and
2708 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002709
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002710- Add -3 option to the interpreter to warn about features that are
2711 deprecated and will be changed/removed in Python 3.0.
2712
Georg Brandl2134e752007-05-21 20:34:16 +00002713- Patch #1686487: you can now pass any mapping after '**' in function
2714 calls.
2715
Collin Winter62903052007-05-18 23:11:24 +00002716- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002717 "except E as target:". This is to provide forwards compatibility
2718 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002719
Brett Cannon229cee22007-05-05 01:34:02 +00002720- Deprecate BaseException.message as per PEP 352.
2721
Georg Brandl3ee81df2008-05-17 18:14:43 +00002722- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002723 inherited from a builtin base.
2724
Vinay Sajip8549ce32007-05-06 17:53:37 +00002725- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002726 setting a plain string, ie don't expand to single letter identifiers.
2727
Raymond Hettinger13936692007-04-11 18:40:58 +00002728- Request #1191699: Slices can now be pickled.
2729
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002730- Request #1193128: str.translate() now allows a None argument for
2731 translations that only remove characters without re-mapping the
2732 remaining characters.
2733
Georg Brandl5cb76c12007-03-21 09:00:39 +00002734- Patch #1682205: a TypeError while unpacking an iterable is no longer
2735 masked by a generic one with the message "unpack non-sequence".
2736
Neal Norwitzaa754b72007-03-21 06:39:48 +00002737- Remove unused file Python/fmod.c.
2738
Guido van Rossum143b5642007-03-23 04:58:42 +00002739- Bug #1683368: The object.__init__() and object.__new__() methods are
2740 now stricter in rejecting excess arguments. The only time when
2741 either allows excess arguments is when it is not overridden and the
2742 other one is. For backwards compatibility, when both are
2743 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002744 warning later). Also, type.__init__() insists on the same signature
2745 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002746
Georg Brandl3ee81df2008-05-17 18:14:43 +00002747- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2748 object to complex using its __complex__() method before falling back
2749 to the __float__() method. Therefore, the functions in the cmath
2750 module now can operate on objects that define a __complex__()
2751 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002752
Georg Brandl3ee81df2008-05-17 18:14:43 +00002753- Patch #1623563: allow __class__ assignment for classes with
2754 __slots__. The old and the new class are still required to have the
2755 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002756
Georg Brandl3ee81df2008-05-17 18:14:43 +00002757- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Patch #1462488: Python no longer segfaults when
2761 ``object.__reduce_ex__()`` is called with an object that is faking
2762 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002763
Georg Brandl3ee81df2008-05-17 18:14:43 +00002764- Patch #1680015: Don't modify __slots__ tuple if it contains an
2765 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00002767- Patch #1444529: the builtin compile() now accepts keyword arguments.
2768
Georg Brandl7b9c5552007-03-12 14:30:05 +00002769- Bug #1678647: write a newline after printing an exception in any
2770 case, even when converting the value to a string failed.
2771
Georg Brandl871f1bc2007-03-12 13:17:36 +00002772- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002773 its argument, if it exists. If not, it will work like before. This
2774 allows customizing the output of dir() in the presence of a
2775 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002776
Collin Winter276887b2007-03-12 16:11:39 +00002777- Patch #922167: Python no longer segfaults when faced with infinitely
2778 self-recursive reload() calls (as reported by bug #742342).
2779
Georg Brandl3ee81df2008-05-17 18:14:43 +00002780- Patch #1675981: remove unreachable code from ``type.__new__()``
2781 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00002782
Georg Brandl3ee81df2008-05-17 18:14:43 +00002783- Patch #1491866: change the complex() constructor to allow
2784 parthensized forms. This means complex(repr(x)) now works instead of
2785 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002786
Georg Brandlaa2321b2007-03-07 00:40:28 +00002787- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002788 makes the filenames the warning module prints much more sensible
2789 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002790
Georg Brandl49aafc92007-03-07 00:34:46 +00002791- Variant of patch #697613: don't exit the interpreter on a SystemExit
2792 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002793 variable is given, but break into the interactive interpreter just
2794 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00002801
Georg Brandl0fca97a2007-03-05 22:28:08 +00002802- Patch #1674228: when assigning a slice (old-style), check for the
2803 sq_ass_slice instead of the sq_slice slot.
2804
Georg Brandl3ee81df2008-05-17 18:14:43 +00002805- When printing an unraisable error, don't print exceptions. before
2806 the name. This duplicates the behavior whening normally printing
2807 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002808
Georg Brandl3ee81df2008-05-17 18:14:43 +00002809- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00002815- Bug #1377858: Fix the segfaulting of the interpreter when an object
2816 created a weakref on itself during a __del__ call for new-style
2817 classes (classic classes still have the bug).

2864
Armin Rigo7ccbca92006-10-04 12:17:45 +00002865- A number of places, including integer negation and absolute value,
2866 were fixed to not rely on undefined behaviour of the C compiler
2867 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00002868
Georg Brandl3267d282006-09-30 09:03:42 +00002869- Bug #1566800: make sure that EnvironmentError can be called with any

2871
Georg Brandl5d59c092006-09-30 08:43:30 +00002872- Patch #1567691: super() and new.instancemethod() now don't accept

Georg Brandl3ee81df2008-05-17 18:14:43 +00002876- Fix a bug in the parser's future statement handling that led to
2877 "with" not being recognized as a keyword after, e.g., this
2878 statement: from __future__ import division, with_statement

3436 exception.

3650
Georg Brandl3ee81df2008-05-17 18:14:43 +00003651- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003717- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3718 with RFC 3207 and forgets any knowledge obtained from the server not
3719 obtained from the TLS negotiation itself. Patch contributed by Bill
3720 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003721
Georg Brandl3ee81df2008-05-17 18:14:43 +00003722- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003723 that the SMTP.starttls() caller no longer needs to call ehlo()
3724 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003725 does not claim to support starttls. Adds the
3726 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3727 Fenner.

3807 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3808 silently miscode subclasses of those types. Now, it raises a
3809 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003810

Georg Brandl3ee81df2008-05-17 18:14:43 +00003825 time so that opening a database previously created with the DB_DUP
3826 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3827 opens. Specifically: dictionary assignment to a DB object will
3828 replace all values for a given key when the database allows
3829 duplicate values. DB users should use DB.put(k, v) when they want
3830 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003831

3837 characters with ASCII value less than 32. Also, it correctly quotes
3838 dots only if they occur on a single line, as opposed to the previous
3839 behavior of quoting dots if they are the second character of any
3840 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003841

Georg Brandldb846032007-03-31 18:56:11 +00004127- Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS
4128 returned by python-config if Python was built with --enable-shared
4129 because that prevented the shared library from being used.
4130

4163-----
4164
Georg Brandl3ee81df2008-05-17 18:14:43 +00004165- Unified naming convention for free lists and their limits. All free
4166 lists in Object/ are named ``free_list``, the counter ``numfree``
4167 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4168 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004169
Georg Brandl3ee81df2008-05-17 18:14:43 +00004170- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4171 to ``PyTuple_SetItem``, it can be used to populate a brand new
4172 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004173
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004174- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

4177 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4178 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004179
4180- Patch #1720595: add T_BOOL to the range of structmember types.
4181
4182- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4183 ``PyFloat_GetInfo()`` to the float API.
4184
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4186 of w# format code incorrectly truncated the length to an int, even
4187 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4188 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4191 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- PEP 3123: Provide forward compatibility with Python 3.0, while
4194 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4195 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4198 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004199
4200- Patch #1733960: Allow T_LONGLONG to accept ints.
4201

4207
4208- Fix some leftovers from the conversion from int to Py_ssize_t
4209 (relevant to strings and sequences of more than 2**31 items).
4210
4211- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4212 outside of pystate.c and should not be necessary.
4213
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4215 absolute imports. In earlier versions they might have used relative
4216 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004217
Georg Brandl3ee81df2008-05-17 18:14:43 +00004218- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4219 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004220
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4227
Georg Brandl3ee81df2008-05-17 18:14:43 +00004228- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4229 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4230 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4231 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004232
Georg Brandl3ee81df2008-05-17 18:14:43 +00004233- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004246- Removed the macfs module. It had been deprecated since Python 2.5.
4247 This lead to the deprecation of macostools.touched() as it relied
4248 solely on macfs and was a no-op under OS X.
