1004- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1005 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1006 really executed because I cannot move to such directory on win2k)
1007
1008- Issue #4069: When set.remove(element) is used with a set element, the element
1009 is temporarily replaced with an equivalent frozenset. But the eventual

1011 it correctly refers to the initial element.

1162
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001163- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1164 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1165 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1166 ``printf`` function, whereas PyString_FromFormat has an independent
1167 implementation and uses "%zd" on all platforms for size_t values.
1168 This makes a difference on win64, where ``printf`` needs "%Id" to display
1169 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001186 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001188- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001189 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1190 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1192 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1193 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001329What's New in Python 2.6 beta 3?
1330================================
1331
Barry Warsaw07a4a382008-08-21 01:15:08 +00001332*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001333
1334Core and Builtins
1335-----------------
1336
Guido van Rossumf8402962008-08-20 15:01:50 +00001337- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1338 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1339 extensions do not automatically benefit from the class attribute
1340 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1341 to their tp_flags field if they care. This is a backwards
1342 compatibility feature; in 3.0, all types will use the cache by
1343 default.
1344
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001345- Keyword arguments can now follow starred arguments. (``f(a, *args,
1346 keyword=23)`` is now valid syntax.)
1347
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001348- ctypes function pointers that are COM methods have a boolean True
1349 value again.
1350
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001351- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1352 by denying s# to parse objects that have a releasebuffer procedure,
1353 and introducing s*.
1354
Georg Brandl1e13ea92008-08-11 09:07:59 +00001355- Issue #3537: Fix an assertion failure when an empty but presized dict
1356 object was stored in the freelist.
1357
Mark Dickinsonb6467572008-08-04 21:30:09 +00001358- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1359 ValueError consistently across platforms.
1360
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001361- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1362 (64bit Unix, for example), unichr() would truncate its argument and return
1363 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1364
Neal Norwitze7d8be82008-07-31 17:17:14 +00001365- Apply security patches from Apple.
1366
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001367- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1368 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1369
Antoine Pitrou92f82162008-07-25 22:22:08 +00001370- Issue #1819: function calls with several named parameters are now on
1371 average 35% faster (as measured by pybench).
1372
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001373- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1374 the python debugger steps into a class statement: the free variables (local
1375 variables defined in an outer scope) would be deleted from the outer scope.
1376
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001377- Issue #2620: Overflow checking when allocating or reallocating memory
1378 was not always being done properly in some python types and extension
1379 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1380 all been updated to perform better checks and places in the code that
1381 would previously leak memory on the error path when such an allocation
1382 failed have been fixed.
1383
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001384Library
1385-------
1386
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001387- Issue #3612: Added some missing basic types in ctypes.wintypes.
1388
Benjamin Petersone977ad42008-08-20 01:42:01 +00001389- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1390 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1391
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001392- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1393 version reported by these tools does not necessarily follow the python
1394 version numbering scheme, so the module is less strict when parsing it.
1395
Nick Coghlanf70385a2008-08-18 12:42:46 +00001396- Issue #2235: Added Py3k warnings for types which will become unhashable
1397 under the stricter __hash__ inheritance rules in 3.0. Several types
1398 which did not meet the rules for hash invariants and were already
1399 unhashable in 3.0 have now been explicitly flagged as unhashable in
1400 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1401 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1402
Brett Cannon88f801d2008-08-18 00:46:22 +00001403- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1404 imported into the module but exposed as part of the module's API.
1405
Brett Cannon7b96f072008-08-18 00:41:11 +00001406- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1407
Brett Cannon46225e72008-08-18 00:36:52 +00001408- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1409
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001410- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1411
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001412- Issue #3575: Incremental decoder's decode function now takes bytearray
1413 by using 's*' instead of 't#'.
1414
Jesus Cea585ad8a2009-07-02 15:37:21 +00001415- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001416 fails unicode conversion on 2nd parameter. (windows only)
1417
Facundo Batista94f243a2008-08-17 03:38:39 +00001418- Issue 2464. urllib2 now supports a malformation in the URL received
1419 in a redirect.
1420
Brett Cannonabe423e2008-08-16 21:47:07 +00001421- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001422 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001423
Facundo Batistaeb90b782008-08-16 14:44:07 +00001424- Issue #2776: fixed small issue when handling an URL with double slash
1425 after a 302 response in the case of not going through a proxy.
1426
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001427- Issue #2676: in the email package, content-type parsing was hanging on
1428 pathological input because of quadratic or exponential behaviour of a
1429 regular expression.
1430
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001431- Issue #3476: binary buffered reading through the new "io" library is now
1432 thread-safe.
1433
Brett Cannonbf3157b2008-08-14 05:00:03 +00001434- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1435 since mimetools itself is deprecated. Because modules are cached, all
1436 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1437
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001438- Issue #3134: shutil referenced undefined WindowsError symbol.
1439
Robert Schuppenies14646332008-08-10 11:01:53 +00001440- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1441 menu entries were not deleted.
1442
Brett Cannon83e81842008-08-09 23:30:55 +00001443- Copied the implementation of reduce() to _functools.reduce() to have a
1444 version that did not raise a DeprecationWarning under -3.
1445
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001446- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1447 a MemoryError rather than silently stop the iteration.
1448
Guido van Rossum59ce9012008-08-09 14:55:34 +00001449- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1450 to _sre.compile() will now be rejected. This should not affect anybody
1451 since the re.compile() function never generates invalid re-bytecode.
1452
Skip Montanaroa032bf42008-08-08 22:52:51 +00001453- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1454 upon first access it can be automatically initialized from the csv file if
1455 it wasn't initialized during instantiation.
1456
Brett Cannon3aa2a492008-08-06 22:28:09 +00001457- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1458 the reload() built-in has been removed.
1459
Brett Cannon7e30b672008-08-04 21:52:25 +00001460- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001461 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1465 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1466 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001467
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001468- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1469 raised an AttributeError.
1470
Benjamin Peterson01a24322008-07-28 23:35:27 +00001471- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001472 asking for a specific length. This problem only affected files opened
1473 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001474
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001475- Issue #3449: Update decimal module to use most recent specification
1476 (v. 1.68) and tests (v. 2.58) from IBM.
1477
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001478- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1479
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001480- Issue 1592: Improve error reporting when operations are attempted
1481 on a closed shelf.

1486
1487- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1488 invalid arguments.
1489
1490- Issue #3302: Fix several crashes when calling locale's gettext functions
1491 with None arguments.
1492
1493- Issue #3389: Allow resolving dotted names for handlers in logging
1494 configuration files.
1495
1496- Deprecate the sunaudio module for removal in Python 3.0.
1497
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001498- Issue #3394: zipfile.writestr sets external attributes when passed a
1499 file name rather than a ZipInfo instance, so files are extracted with
1500 mode 0600 rather than 000 under Unix.
1501
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001502- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1503 argument in python 2.5, this broke code that subclassed Popen to include its
1504 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001514- Issue #2235: the C API function PyObject_HashNotImplemented and its
1515 interaction with the tp_hash slot (added in 2.6b2) are now documented
1516
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001517- Issue #643841: The language reference now provides more detailed
1518 coverage of the lookup process for special methods. The disclaimers
1519 regarding lack of coverage of new-style classes have also been
1520 removed, since the coverage is now fairly reasonable.

1529-----------------
1530
Georg Brandl3e483f62008-07-16 22:57:41 +00001531- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1532 its methods now allow for items objects that can be converted to
1533 an integer using operator.index().
1534
Mark Dickinson64b7e502008-07-16 09:40:03 +00001535- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1536 produced a ValueError instead of giving the correct float.
1537
Eric Smitha5fa5a22008-07-16 00:11:49 +00001538- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1539 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1540
Mark Dickinson7103aa42008-07-15 19:08:33 +00001541- Issue #3008: the float type has a new instance method 'float.hex'
1542 and a new class method 'float.fromhex' to convert floating-point
1543 numbers to and from hexadecimal strings, respectively.
1544
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001545- Issue #2235: __hash__ is once again inherited by default. To allow
1546 collections.Hashable to remain meaningful in the presence of the
1547 default hash implementation (object.__hash__), it is now possible
1548 to explicit block inheritance of hash by setting __hash__=None at
1549 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1550 level.
1551
Nick Coghlanb028f502008-07-13 14:52:36 +00001552- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1553 the parent module cannot be found while performing an absolute import.
1554 This means that an incorrectly defined __package__ attribute will
1555 now only prevent relative imports in that module rather than causing
1556 all imports from that module to fail.
1557
Nick Coghlan14ff9942008-07-08 14:21:42 +00001558- Issue #2517: Allow unicode messages in Exceptions again by correctly
1559 bypassing the instance dictionary when looking up __unicode__ on
1560 new-style classes.
1561
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001562- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1563 set to a custom object whose write() method happens to install
1564 another file in sys.stdout.

1568 another thread's dictionary.
1569
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001570- Issue #3004: Minor change to slice.indices(): the start and stop
1571 arguments are now treated identically, making the behaviour easier
1572 to describe and understand. For example, slice(None, -10,
1573 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1574 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1575 10, -1).
1576
Georg Brandl278fc502008-07-19 12:46:12 +00001577- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00002029 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002030
2031 This is controlled by the configure argument ``--with-universal-archs``:
2032

Georg Brandl3ee81df2008-05-17 18:14:43 +00002091- Issue #1631171: Re-implement the 'warnings' module in C (the
2092 original Python code has been kept as backup). This will allow for
2093 using the 'warning's machinery in such places as the parser where
2094 use of pure Python code is not possible. Both the ``showarning()``
2095 and ``formatwarning()`` gain an optional 'line' argument which is
2096 not called by default for backwards-compatibility reasons. Setting
2097 ``warnings.showwarning()`` to an implementation that lacks support
2098 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002153- Issue #2385: distutils.core.run_script() makes __file__ available,
2154 so the controlled environment will more closely mirror the typical
2155 script environment. This supports setup.py scripts that refer to
2156 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002161- Issue #2550: The approach used by client/server code for obtaining
2162 ports to listen on in network-oriented tests has been refined in an
2163 effort to facilitate running multiple instances of the entire
2164 regression test suite in parallel without issue.
2165 test_support.bind_port() has been fixed such that it will always
2166 return a unique port -- which wasn't always the case with the
2167 previous implementation, especially if socket options had been set
2168 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2169 new implementation of bind_port() will actually raise an exception
2170 if it is passed an AF_INET/SOCK_STREAM socket with either the
2171 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2172 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2173 the socket it's been passed. This currently only applies to
2174 Windows. This option prevents any other sockets from binding to the
2175 host/port we've bound to, thus removing the possibility of the
2176 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2177 when a second SOCK_STREAM socket binds and accepts to a host/port
2178 that's already been bound by another socket. The optional preferred
2179 port parameter to bind_port() has been removed. Under no
2180 circumstances should tests be hard coding ports!
2181
2182 test_support.find_unused_port() has also been introduced, which will
2183 pass a temporary socket object to bind_port() in order to obtain an
2184 unused port. The temporary socket object is then closed and
2185 deleted, and the port is returned. This method should only be used
2186 for obtaining an unused port in order to pass to an external program
2187 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2188 a parameter to a server-oriented class that doesn't give you direct
2189 access to the underlying socket used.
2190
2191 Finally, test_support.HOST has been introduced, which should be used
2192 for the host argument of any relevant socket calls (i.e. bind and
2193 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002194
2195 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002196 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002197 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2198 test_asynchat and test_socket_ssl.
2199
Georg Brandl3ee81df2008-05-17 18:14:43 +00002200 It is now possible for multiple instances of the regression test
2201 suite to run in parallel without issue.

2468-----------------
2469
Fred Drakea8ee94b2008-03-01 02:45:07 +00002470- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002471 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002472
Georg Brandlad61bc82008-02-23 15:11:18 +00002473- Issue #2067: file.__exit__() now calls subclasses' close() method.
2474
2475- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002476
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002477- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002478 issue 215555 for a discussion.
2479
Eric Smitha73fbe72008-02-23 03:09:44 +00002480- Added the future_builtins module, which contains hex() and oct().
2481 These are the PEP 3127 version of these functions, designed to be
2482 compatible with the hex() and oct() builtins from Python 3.0. They
2483 differ slightly in their output formats from the existing, unchanged
2484 Python 2.6 builtins. The expected usage of the future_builtins
2485 module is:
2486 from future_builtins import hex, oct
2487
Eric Smith7ef40bf2008-02-20 23:34:22 +00002488- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2489 exponents for exponents with absolute value < 100. Follows C99
2490 standard. This is a change on Windows, which would use 3 digits.
2491 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2492 so that any alterations it does to the resulting string will be
2493 available in stringlib/formatter.h (for float.__format__).
2494
Eric Smith5a3c1352008-02-19 13:21:56 +00002495- Implemented PEP 3101, Advanced String Formatting. This adds a new
2496 builtin format(); a format() method for str and unicode; a
2497 __format__() method to object, str, unicode, int, long, float, and
2498 datetime; the class string.Formatter; and the C API
2499 PyObject_Format().
2500
Georg Brandl3ee81df2008-05-17 18:14:43 +00002501- Fixed several potential crashes, all caused by specially crafted
2502 __del__ methods exploiting objects in temporarily inconsistent
2503 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002504
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002505- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002506 prevent a possible crash: an Abstract Base Class would try to access
2507 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002508
Georg Brandl3ee81df2008-05-17 18:14:43 +00002509- Fixed repr() and str() of complex numbers with infinity or nan as
2510 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002512- Clear all free lists during a gc.collect() of the highest generation
2513 in order to allow pymalloc to free more arenas. Python may give back
2514 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002515
Georg Brandl3ee81df2008-05-17 18:14:43 +00002516- Issue #2045: Fix an infinite recursion triggered when printing a
2517 subclass of collections.defaultdict, if its default_factory is set
2518 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002519
Christian Heimesf75dbef2008-02-08 00:11:31 +00002520- Fixed a minor memory leak in dictobject.c. The content of the free
2521 list was not freed on interpreter shutdown.
2522
Georg Brandl3ee81df2008-05-17 18:14:43 +00002523- Limit free list of method and builtin function objects to 256
2524 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002525
Georg Brandl3ee81df2008-05-17 18:14:43 +00002526- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2527 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002528 to compact the internal free lists of pre-allocted ints and floats.
2529
Georg Brandl3ee81df2008-05-17 18:14:43 +00002530- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2531 calls. Python expected the return type int but the fork familie
2532 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002533
Georg Brandl3ee81df2008-05-17 18:14:43 +00002534- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2535 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002536

2544 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002545
Georg Brandl3ee81df2008-05-17 18:14:43 +00002546- Patch #1473257: generator objects gain a gi_code attribute. This is
2547 the same object as the func_code attribute of the function that
2548 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002549
Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Issue #1920: "while 0" statements were completely removed by the
2551 compiler, even in the presence of an "else" clause, which is
2552 supposed to be run when the condition is false. Now the compiler
2553 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002554
Guido van Rossumeead05f2008-01-24 18:21:02 +00002555- A few crashers fixed: weakref_in_del.py (issue #1377858);
2556 loosing_dict_ref.py (issue #1303614, test67.py);
2557 borrowed_ref_[34].py (not in tracker).
2558
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002559- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002560 suppressed while an extension is loaded by calling SetErrorMode in
2561 dynload_win.c. The error is still reported properly.
2562
Georg Brandl3ee81df2008-05-17 18:14:43 +00002563- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002564 several extension methods and modules do not work without unicode
2565 support.
2566
Georg Brandl26543b12008-01-21 18:36:51 +00002567- Issue #1882: when compiling code from a string, encoding cookies in the
2568 second line of code were not always recognized correctly.
2569
Georg Brandl14404b62008-01-19 19:27:05 +00002570- Issue #1679: "0x" was taken as a valid integer literal.
2571
Georg Brandl6caad7d2008-01-26 14:19:22 +00002572- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002573 added.
2574
Christian Heimesc94e2b52008-01-14 04:13:37 +00002575- sys.float_info / PyFloat_GetInfo: The floating point information
2576 object was converted from a dict to a specialized structseq object.
2577
Georg Brandl3ee81df2008-05-17 18:14:43 +00002578- Patch #1816: Added sys.flags structseq. It exposes the status of
2579 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002580
Georg Brandl3ee81df2008-05-17 18:14:43 +00002581- Objects/structseq.c: Implemented new structseq representation. The
2582 patch makes structseqs (e.g. the return value of os.stat) more
2583 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002584
Georg Brandl3ee81df2008-05-17 18:14:43 +00002585- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002657- The enumerate() builtin function is no longer bounded to sequences
2658 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2659 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002660
Georg Brandl3ee81df2008-05-17 18:14:43 +00002661- Issue #1686386: Tuple's tp_repr did not take into account the
2662 possibility of having a self-referential tuple, which is possible
2663 from C code. Nor did object's tp_str consider that a type's tp_str
2664 could do something that could lead to an inifinite recursion.
2665 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2666 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002667
Georg Brandl3ee81df2008-05-17 18:14:43 +00002668- Issue #1164: It was possible to trigger deadlock when using the
2669 'print' statement to write to a file since the GIL was not released
2670 as needed. Now PyObject_Print() does the right thing along with
2671 various tp_print implementations of the built-in types and those in
2672 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002673
Georg Brandl3ee81df2008-05-17 18:14:43 +00002674- Issue #1147: Exceptions were directly allowing string exceptions in
2675 their throw() method even though string exceptions no longer
2676 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002677
Georg Brandl3ee81df2008-05-17 18:14:43 +00002678- Issue #1096: Prevent a segfault from getting the repr of a very
2679 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002680
Brett Cannon1e534b52007-09-07 04:18:30 +00002681- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002682 PyObject_Call() never calling back out to Python code to trigger
2683 recursion depth updates/checks. Required the creation of a static
2684 RuntimeError instance in case normalizing an exception put the
2685 recursion check value past its limit. Fixes crashers
2686 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002687

Neal Norwitz0ac60192007-05-27 04:08:54 +00002701- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002702 __*__ attributes. (Some already existed, e.g., __doc__ and
2703 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002704
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002705- Add -3 option to the interpreter to warn about features that are
2706 deprecated and will be changed/removed in Python 3.0.
2707
Georg Brandl2134e752007-05-21 20:34:16 +00002708- Patch #1686487: you can now pass any mapping after '**' in function
2709 calls.
2710
Collin Winter62903052007-05-18 23:11:24 +00002711- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002712 "except E as target:". This is to provide forwards compatibility
2713 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002714
Brett Cannon229cee22007-05-05 01:34:02 +00002715- Deprecate BaseException.message as per PEP 352.
2716
Georg Brandl3ee81df2008-05-17 18:14:43 +00002717- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002718 inherited from a builtin base.
2719
Vinay Sajip8549ce32007-05-06 17:53:37 +00002720- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002721 setting a plain string, ie don't expand to single letter identifiers.
2722
Raymond Hettinger13936692007-04-11 18:40:58 +00002723- Request #1191699: Slices can now be pickled.
2724
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002725- Request #1193128: str.translate() now allows a None argument for
2726 translations that only remove characters without re-mapping the
2727 remaining characters.
2728
Georg Brandl5cb76c12007-03-21 09:00:39 +00002729- Patch #1682205: a TypeError while unpacking an iterable is no longer
2730 masked by a generic one with the message "unpack non-sequence".
2731
Neal Norwitzaa754b72007-03-21 06:39:48 +00002732- Remove unused file Python/fmod.c.
2733
Guido van Rossum143b5642007-03-23 04:58:42 +00002734- Bug #1683368: The object.__init__() and object.__new__() methods are
2735 now stricter in rejecting excess arguments. The only time when
2736 either allows excess arguments is when it is not overridden and the
2737 other one is. For backwards compatibility, when both are
2738 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002739 warning later). Also, type.__init__() insists on the same signature
2740 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002741
Georg Brandl3ee81df2008-05-17 18:14:43 +00002742- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2743 object to complex using its __complex__() method before falling back
2744 to the __float__() method. Therefore, the functions in the cmath
2745 module now can operate on objects that define a __complex__()
2746 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002747
Georg Brandl3ee81df2008-05-17 18:14:43 +00002748- Patch #1623563: allow __class__ assignment for classes with
2749 __slots__. The old and the new class are still required to have the
2750 same slot names.

2756 ``object.__reduce_ex__()`` is called with an object that is faking
2757 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002758
Georg Brandl3ee81df2008-05-17 18:14:43 +00002759- Patch #1680015: Don't modify __slots__ tuple if it contains an

2763
Georg Brandl7b9c5552007-03-12 14:30:05 +00002764- Bug #1678647: write a newline after printing an exception in any
2765 case, even when converting the value to a string failed.
2766
Georg Brandl871f1bc2007-03-12 13:17:36 +00002767- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002768 its argument, if it exists. If not, it will work like before. This
2769 allows customizing the output of dir() in the presence of a
2770 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002771
Collin Winter276887b2007-03-12 16:11:39 +00002772- Patch #922167: Python no longer segfaults when faced with infinitely
2773 self-recursive reload() calls (as reported by bug #742342).
2774

2779 parthensized forms. This means complex(repr(x)) now works instead of
2780 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002781
Georg Brandlaa2321b2007-03-07 00:40:28 +00002782- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002783 makes the filenames the warning module prints much more sensible
2784 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002785

Georg Brandl0fca97a2007-03-05 22:28:08 +00002797- Patch #1674228: when assigning a slice (old-style), check for the
2798 sq_ass_slice instead of the sq_slice slot.
2799
Georg Brandl3ee81df2008-05-17 18:14:43 +00002800- When printing an unraisable error, don't print exceptions. before
2801 the name. This duplicates the behavior whening normally printing
2802 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002903 generator expressions (x for x, in ... ) works again. Fixing this

3431 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003712- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3713 with RFC 3207 and forgets any knowledge obtained from the server not
3714 obtained from the TLS negotiation itself. Patch contributed by Bill
3715 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003716
Georg Brandl3ee81df2008-05-17 18:14:43 +00003717- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003718 that the SMTP.starttls() caller no longer needs to call ehlo()
3719 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003720 does not claim to support starttls. Adds the
3721 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3802 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3803 silently miscode subclasses of those types. Now, it raises a
3804 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003805

Georg Brandl3ee81df2008-05-17 18:14:43 +00003820 time so that opening a database previously created with the DB_DUP
3821 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3822 opens. Specifically: dictionary assignment to a DB object will
3823 replace all values for a given key when the database allows
3824 duplicate values. DB users should use DB.put(k, v) when they want
3825 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003826

3832 characters with ASCII value less than 32. Also, it correctly quotes
3833 dots only if they occur on a single line, as opposed to the previous
3834 behavior of quoting dots if they are the second character of any
3835 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003836

4158-----
4159
Georg Brandl3ee81df2008-05-17 18:14:43 +00004160- Unified naming convention for free lists and their limits. All free
4161 lists in Object/ are named ``free_list``, the counter ``numfree``
4162 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4163 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004164
Georg Brandl3ee81df2008-05-17 18:14:43 +00004165- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4166 to ``PyTuple_SetItem``, it can be used to populate a brand new
4167 frozenset; but it does not steal a reference to the added item.

4172 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4173 PyLong_FromSsize_t public functions.

4175- Patch #1720595: add T_BOOL to the range of structmember types.
4176
4177- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4178 ``PyFloat_GetInfo()`` to the float API.
4179
Georg Brandl3ee81df2008-05-17 18:14:43 +00004180- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4181 of w# format code incorrectly truncated the length to an int, even
4182 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4183 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004184
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4203- Fix some leftovers from the conversion from int to Py_ssize_t
4204 (relevant to strings and sequences of more than 2**31 items).
4205
4206- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4207 outside of pystate.c and should not be necessary.
4208
Georg Brandl3ee81df2008-05-17 18:14:43 +00004209- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4210 absolute imports. In earlier versions they might have used relative
4211 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004212
Georg Brandl3ee81df2008-05-17 18:14:43 +00004213- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4214 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004215
Georg Brandl3ee81df2008-05-17 18:14:43 +00004216- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004223- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4224 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4225 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4226 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004227

Georg Brandl3ee81df2008-05-17 18:14:43 +00004241- Removed the macfs module. It had been deprecated since Python 2.5.
4242 This lead to the deprecation of macostools.touched() as it relied
4243 solely on macfs and was a no-op under OS X.
