819 302 conformant loader) will now work correctly in most cases (they
820 are still subject to the constraints that exist for all code running

988- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
989 interpreter to abort ("Fatal Python error: Could not reset the stack!")
990 instead of throwing a MemoryError.
991
992- Issue #4367: Python would segfault during compiling when the unicodedata
993 module couldn't be imported and \N escapes were present.

995- Issue #4348: Some bytearray methods returned that didn't cause any change to
996 the bytearray, returned the same bytearray instead of a copy.

1008 method does not return iterators for the 4th and 5th items.
1009
1010- Issue #4209: Enabling unicode_literals and the print_function in the same
1011 __future__ import didn't work.
1012
1013- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1014 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1015 really executed because I cannot move to such directory on win2k)
1016
1017- Issue #4069: When set.remove(element) is used with a set element, the element
1018 is temporarily replaced with an equivalent frozenset. But the eventual
1019 KeyError would always report the empty frozenset([]) as the missing key. Now
1020 it correctly refers to the initial element.
1021
1022- Fixed C99 style comments in several files. Python is now C89 compatible
1023 again.

1171
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001172- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1173 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1174 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1175 ``printf`` function, whereas PyString_FromFormat has an independent
1176 implementation and uses "%zd" on all platforms for size_t values.
1177 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitrou0668c622008-08-26 22:42:08 +00001198 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1199 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1201 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1202 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001338What's New in Python 2.6 beta 3?
1339================================
1340
Barry Warsaw07a4a382008-08-21 01:15:08 +00001341*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001342
1343Core and Builtins
1344-----------------
1345
Guido van Rossumf8402962008-08-20 15:01:50 +00001346- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1347 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1348 extensions do not automatically benefit from the class attribute
1349 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1350 to their tp_flags field if they care. This is a backwards
1351 compatibility feature; in 3.0, all types will use the cache by
1352 default.
1353
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001354- Keyword arguments can now follow starred arguments. (``f(a, *args,
1355 keyword=23)`` is now valid syntax.)
1356
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001357- ctypes function pointers that are COM methods have a boolean True
1358 value again.
1359
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001360- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1361 by denying s# to parse objects that have a releasebuffer procedure,
1362 and introducing s*.
1363
Georg Brandl1e13ea92008-08-11 09:07:59 +00001364- Issue #3537: Fix an assertion failure when an empty but presized dict
1365 object was stored in the freelist.
1366
Mark Dickinsonb6467572008-08-04 21:30:09 +00001367- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1368 ValueError consistently across platforms.
1369
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001370- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1371 (64bit Unix, for example), unichr() would truncate its argument and return
1372 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1373
Neal Norwitze7d8be82008-07-31 17:17:14 +00001374- Apply security patches from Apple.
1375
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001376- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1377 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1378
Antoine Pitrou92f82162008-07-25 22:22:08 +00001379- Issue #1819: function calls with several named parameters are now on
1380 average 35% faster (as measured by pybench).
1381
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001382- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1383 the python debugger steps into a class statement: the free variables (local
1384 variables defined in an outer scope) would be deleted from the outer scope.
1385
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001386- Issue #2620: Overflow checking when allocating or reallocating memory
1387 was not always being done properly in some python types and extension
1388 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1389 all been updated to perform better checks and places in the code that
1390 would previously leak memory on the error path when such an allocation
1391 failed have been fixed.
1392
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001393Library
1394-------
1395
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001396- Issue #3612: Added some missing basic types in ctypes.wintypes.
1397
Benjamin Petersone977ad42008-08-20 01:42:01 +00001398- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1399 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1400
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001401- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1402 version reported by these tools does not necessarily follow the python
1403 version numbering scheme, so the module is less strict when parsing it.
1404
Nick Coghlanf70385a2008-08-18 12:42:46 +00001405- Issue #2235: Added Py3k warnings for types which will become unhashable
1406 under the stricter __hash__ inheritance rules in 3.0. Several types
1407 which did not meet the rules for hash invariants and were already
1408 unhashable in 3.0 have now been explicitly flagged as unhashable in
1409 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1410 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1411
Brett Cannon88f801d2008-08-18 00:46:22 +00001412- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1413 imported into the module but exposed as part of the module's API.
1414
Brett Cannon7b96f072008-08-18 00:41:11 +00001415- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1416
Brett Cannon46225e72008-08-18 00:36:52 +00001417- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1418
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001419- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1420
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001421- Issue #3575: Incremental decoder's decode function now takes bytearray
1422 by using 's*' instead of 't#'.
1423
Jesus Cea585ad8a2009-07-02 15:37:21 +00001424- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001425 fails unicode conversion on 2nd parameter. (windows only)
1426
Facundo Batista94f243a2008-08-17 03:38:39 +00001427- Issue 2464. urllib2 now supports a malformation in the URL received
1428 in a redirect.
1429
Brett Cannonabe423e2008-08-16 21:47:07 +00001430- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001431 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001432
Facundo Batistaeb90b782008-08-16 14:44:07 +00001433- Issue #2776: fixed small issue when handling an URL with double slash
1434 after a 302 response in the case of not going through a proxy.
1435
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001436- Issue #2676: in the email package, content-type parsing was hanging on
1437 pathological input because of quadratic or exponential behaviour of a
1438 regular expression.
1439
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001440- Issue #3476: binary buffered reading through the new "io" library is now
1441 thread-safe.
1442
Brett Cannonbf3157b2008-08-14 05:00:03 +00001443- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1444 since mimetools itself is deprecated. Because modules are cached, all
1445 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1446
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001447- Issue #3134: shutil referenced undefined WindowsError symbol.
1448
Robert Schuppenies14646332008-08-10 11:01:53 +00001449- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1450 menu entries were not deleted.
1451
Brett Cannon83e81842008-08-09 23:30:55 +00001452- Copied the implementation of reduce() to _functools.reduce() to have a
1453 version that did not raise a DeprecationWarning under -3.
1454
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001455- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1456 a MemoryError rather than silently stop the iteration.
1457
Guido van Rossum59ce9012008-08-09 14:55:34 +00001458- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1459 to _sre.compile() will now be rejected. This should not affect anybody
1460 since the re.compile() function never generates invalid re-bytecode.
1461
Skip Montanaroa032bf42008-08-08 22:52:51 +00001462- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1463 upon first access it can be automatically initialized from the csv file if
1464 it wasn't initialized during instantiation.
1465
Brett Cannon3aa2a492008-08-06 22:28:09 +00001466- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1467 the reload() built-in has been removed.
1468
Brett Cannon7e30b672008-08-04 21:52:25 +00001469- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001470 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1473 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1474 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1475 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001476
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001477- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1478 raised an AttributeError.
1479
Benjamin Peterson01a24322008-07-28 23:35:27 +00001480- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001481 asking for a specific length. This problem only affected files opened
1482 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001483
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001484- Issue #3449: Update decimal module to use most recent specification
1485 (v. 1.68) and tests (v. 2.58) from IBM.
1486
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001487- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1488

1495
1496- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1497 invalid arguments.
1498
1499- Issue #3302: Fix several crashes when calling locale's gettext functions
1500 with None arguments.
1501
1502- Issue #3389: Allow resolving dotted names for handlers in logging
1503 configuration files.
1504
1505- Deprecate the sunaudio module for removal in Python 3.0.
1506
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001507- Issue #3394: zipfile.writestr sets external attributes when passed a
1508 file name rather than a ZipInfo instance, so files are extracted with
1509 mode 0600 rather than 000 under Unix.
1510
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001511- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1512 argument in python 2.5, this broke code that subclassed Popen to include its
1513 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001523- Issue #2235: the C API function PyObject_HashNotImplemented and its
1524 interaction with the tp_hash slot (added in 2.6b2) are now documented
1525
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001526- Issue #643841: The language reference now provides more detailed
1527 coverage of the lookup process for special methods. The disclaimers
1528 regarding lack of coverage of new-style classes have also been
1529 removed, since the coverage is now fairly reasonable.

1534
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001535*Release date: 17-Jul-2008*

1538-----------------
1539
Georg Brandl3e483f62008-07-16 22:57:41 +00001540- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1541 its methods now allow for items objects that can be converted to
1542 an integer using operator.index().
1543
Mark Dickinson64b7e502008-07-16 09:40:03 +00001544- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1545 produced a ValueError instead of giving the correct float.
1546
Eric Smitha5fa5a22008-07-16 00:11:49 +00001547- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1548 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1549
Mark Dickinson7103aa42008-07-15 19:08:33 +00001550- Issue #3008: the float type has a new instance method 'float.hex'
1551 and a new class method 'float.fromhex' to convert floating-point
1552 numbers to and from hexadecimal strings, respectively.
1553
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001554- Issue #2235: __hash__ is once again inherited by default. To allow
1555 collections.Hashable to remain meaningful in the presence of the
1556 default hash implementation (object.__hash__), it is now possible
1557 to explicit block inheritance of hash by setting __hash__=None at
1558 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1559 level.
1560
Nick Coghlanb028f502008-07-13 14:52:36 +00001561- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1562 the parent module cannot be found while performing an absolute import.
1563 This means that an incorrectly defined __package__ attribute will
1564 now only prevent relative imports in that module rather than causing
1565 all imports from that module to fail.
1566
Nick Coghlan14ff9942008-07-08 14:21:42 +00001567- Issue #2517: Allow unicode messages in Exceptions again by correctly
1568 bypassing the instance dictionary when looking up __unicode__ on
1569 new-style classes.
1570
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001571- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1572 set to a custom object whose write() method happens to install
1573 another file in sys.stdout.

1577 another thread's dictionary.
1578
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001579- Issue #3004: Minor change to slice.indices(): the start and stop
1580 arguments are now treated identically, making the behaviour easier
1581 to describe and understand. For example, slice(None, -10,
1582 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1583 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1584 10, -1).
1585
Georg Brandl278fc502008-07-19 12:46:12 +00001586- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl3ee81df2008-05-17 18:14:43 +00002100- Issue #1631171: Re-implement the 'warnings' module in C (the
2101 original Python code has been kept as backup). This will allow for
2102 using the 'warning's machinery in such places as the parser where
2103 use of pure Python code is not possible. Both the ``showarning()``
2104 and ``formatwarning()`` gain an optional 'line' argument which is
2105 not called by default for backwards-compatibility reasons. Setting
2106 ``warnings.showwarning()`` to an implementation that lacks support
2107 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002162- Issue #2385: distutils.core.run_script() makes __file__ available,
2163 so the controlled environment will more closely mirror the typical
2164 script environment. This supports setup.py scripts that refer to
2165 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002170- Issue #2550: The approach used by client/server code for obtaining
2171 ports to listen on in network-oriented tests has been refined in an
2172 effort to facilitate running multiple instances of the entire
2173 regression test suite in parallel without issue.
2174 test_support.bind_port() has been fixed such that it will always
2175 return a unique port -- which wasn't always the case with the
2176 previous implementation, especially if socket options had been set
2177 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2178 new implementation of bind_port() will actually raise an exception
2179 if it is passed an AF_INET/SOCK_STREAM socket with either the
2180 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2181 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2182 the socket it's been passed. This currently only applies to
2183 Windows. This option prevents any other sockets from binding to the
2184 host/port we've bound to, thus removing the possibility of the
2185 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2186 when a second SOCK_STREAM socket binds and accepts to a host/port
2187 that's already been bound by another socket. The optional preferred
2188 port parameter to bind_port() has been removed. Under no
2189 circumstances should tests be hard coding ports!
2190
2191 test_support.find_unused_port() has also been introduced, which will
2192 pass a temporary socket object to bind_port() in order to obtain an
2193 unused port. The temporary socket object is then closed and
2194 deleted, and the port is returned. This method should only be used
2195 for obtaining an unused port in order to pass to an external program
2196 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2197 a parameter to a server-oriented class that doesn't give you direct
2198 access to the underlying socket used.
2199
2200 Finally, test_support.HOST has been introduced, which should be used
2201 for the host argument of any relevant socket calls (i.e. bind and
2202 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002203
2204 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002205 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002206 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2207 test_asynchat and test_socket_ssl.
2208
Georg Brandl3ee81df2008-05-17 18:14:43 +00002209 It is now possible for multiple instances of the regression test
2210 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002416 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2417 files are used. On all linux systems the --with-system-ffi
2418 configure option defaults to "yes".

2477-----------------
2478
Fred Drakea8ee94b2008-03-01 02:45:07 +00002479- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002480 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002481
Georg Brandlad61bc82008-02-23 15:11:18 +00002482- Issue #2067: file.__exit__() now calls subclasses' close() method.
2483
2484- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002485
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002486- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002487 issue 215555 for a discussion.
2488
Eric Smitha73fbe72008-02-23 03:09:44 +00002489- Added the future_builtins module, which contains hex() and oct().
2490 These are the PEP 3127 version of these functions, designed to be
2491 compatible with the hex() and oct() builtins from Python 3.0. They
2492 differ slightly in their output formats from the existing, unchanged
2493 Python 2.6 builtins. The expected usage of the future_builtins
2494 module is:
2495 from future_builtins import hex, oct
2496
Eric Smith7ef40bf2008-02-20 23:34:22 +00002497- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2498 exponents for exponents with absolute value < 100. Follows C99
2499 standard. This is a change on Windows, which would use 3 digits.
2500 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2501 so that any alterations it does to the resulting string will be
2502 available in stringlib/formatter.h (for float.__format__).
2503
Eric Smith5a3c1352008-02-19 13:21:56 +00002504- Implemented PEP 3101, Advanced String Formatting. This adds a new
2505 builtin format(); a format() method for str and unicode; a
2506 __format__() method to object, str, unicode, int, long, float, and
2507 datetime; the class string.Formatter; and the C API
2508 PyObject_Format().
2509
Georg Brandl3ee81df2008-05-17 18:14:43 +00002510- Fixed several potential crashes, all caused by specially crafted
2511 __del__ methods exploiting objects in temporarily inconsistent
2512 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002513
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002514- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002515 prevent a possible crash: an Abstract Base Class would try to access
2516 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002517
Georg Brandl3ee81df2008-05-17 18:14:43 +00002518- Fixed repr() and str() of complex numbers with infinity or nan as
2519 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002520
Georg Brandl3ee81df2008-05-17 18:14:43 +00002521- Clear all free lists during a gc.collect() of the highest generation
2522 in order to allow pymalloc to free more arenas. Python may give back
2523 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002524
Georg Brandl3ee81df2008-05-17 18:14:43 +00002525- Issue #2045: Fix an infinite recursion triggered when printing a
2526 subclass of collections.defaultdict, if its default_factory is set
2527 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002528
Christian Heimesf75dbef2008-02-08 00:11:31 +00002529- Fixed a minor memory leak in dictobject.c. The content of the free
2530 list was not freed on interpreter shutdown.
2531
Georg Brandl3ee81df2008-05-17 18:14:43 +00002532- Limit free list of method and builtin function objects to 256
2533 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002534
Georg Brandl3ee81df2008-05-17 18:14:43 +00002535- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2536 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002537 to compact the internal free lists of pre-allocted ints and floats.
2538
Georg Brandl3ee81df2008-05-17 18:14:43 +00002539- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2540 calls. Python expected the return type int but the fork familie
2541 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002542
Georg Brandl3ee81df2008-05-17 18:14:43 +00002543- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2544 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002545
Georg Brandl3ee81df2008-05-17 18:14:43 +00002546- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2547 with the collections.Sequence API.

2553 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002554
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555- Patch #1473257: generator objects gain a gi_code attribute. This is
2556 the same object as the func_code attribute of the function that
2557 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002558
Georg Brandl3ee81df2008-05-17 18:14:43 +00002559- Issue #1920: "while 0" statements were completely removed by the
2560 compiler, even in the presence of an "else" clause, which is
2561 supposed to be run when the condition is false. Now the compiler
2562 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002563
Guido van Rossumeead05f2008-01-24 18:21:02 +00002564- A few crashers fixed: weakref_in_del.py (issue #1377858);
2565 loosing_dict_ref.py (issue #1303614, test67.py);
2566 borrowed_ref_[34].py (not in tracker).
2567
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002568- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002569 suppressed while an extension is loaded by calling SetErrorMode in
2570 dynload_win.c. The error is still reported properly.
2571
Georg Brandl3ee81df2008-05-17 18:14:43 +00002572- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002573 several extension methods and modules do not work without unicode
2574 support.
2575
Georg Brandl26543b12008-01-21 18:36:51 +00002576- Issue #1882: when compiling code from a string, encoding cookies in the
2577 second line of code were not always recognized correctly.
2578
Georg Brandl14404b62008-01-19 19:27:05 +00002579- Issue #1679: "0x" was taken as a valid integer literal.
2580
Georg Brandl6caad7d2008-01-26 14:19:22 +00002581- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002582 added.
2583
Christian Heimesc94e2b52008-01-14 04:13:37 +00002584- sys.float_info / PyFloat_GetInfo: The floating point information
2585 object was converted from a dict to a specialized structseq object.
2586
Georg Brandl3ee81df2008-05-17 18:14:43 +00002587- Patch #1816: Added sys.flags structseq. It exposes the status of
2588 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002589
Georg Brandl3ee81df2008-05-17 18:14:43 +00002590- Objects/structseq.c: Implemented new structseq representation. The
2591 patch makes structseqs (e.g. the return value of os.stat) more
2592 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002593
Georg Brandl3ee81df2008-05-17 18:14:43 +00002594- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002606- Improve some exception messages when Windows fails to load an
2607 extension module. Now we get for example '%1 is not a valid Win32
2608 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002616 and INF. float("nan"), float("inf") and float("-inf") now work on
2617 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002618
Georg Brandl3ee81df2008-05-17 18:14:43 +00002619- Compiler now generates simpler and faster code for dictionary
2620 literals. The oparg for BUILD_MAP now indicates an estimated
2621 dictionary size. There is a new opcode, STORE_MAP, for adding
2622 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002656- Issue #1265: Fix a problem with sys.settrace, if the tracing
2657 function uses a generator expression when at the same time the
2658 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002659
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002660- sets and frozensets now have an isdisjoint() method.
2661

2663
Neal Norwitz44f326e2007-10-05 05:29:17 +00002664- Fix warnings found by the new version of the Coverity checker.
2665
Georg Brandl3ee81df2008-05-17 18:14:43 +00002666- The enumerate() builtin function is no longer bounded to sequences
2667 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2668 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002669
Georg Brandl3ee81df2008-05-17 18:14:43 +00002670- Issue #1686386: Tuple's tp_repr did not take into account the
2671 possibility of having a self-referential tuple, which is possible
2672 from C code. Nor did object's tp_str consider that a type's tp_str
2673 could do something that could lead to an inifinite recursion.
2674 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2675 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002676
Georg Brandl3ee81df2008-05-17 18:14:43 +00002677- Issue #1164: It was possible to trigger deadlock when using the
2678 'print' statement to write to a file since the GIL was not released
2679 as needed. Now PyObject_Print() does the right thing along with
2680 various tp_print implementations of the built-in types and those in
2681 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002682
Georg Brandl3ee81df2008-05-17 18:14:43 +00002683- Issue #1147: Exceptions were directly allowing string exceptions in
2684 their throw() method even though string exceptions no longer
2685 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002686
Georg Brandl3ee81df2008-05-17 18:14:43 +00002687- Issue #1096: Prevent a segfault from getting the repr of a very
2688 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002689
Brett Cannon1e534b52007-09-07 04:18:30 +00002690- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002691 PyObject_Call() never calling back out to Python code to trigger
2692 recursion depth updates/checks. Required the creation of a static
2693 RuntimeError instance in case normalizing an exception put the
2694 recursion check value past its limit. Fixes crashers
2695 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002696
Georg Brandl3ee81df2008-05-17 18:14:43 +00002697- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002710- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002711 __*__ attributes. (Some already existed, e.g., __doc__ and
2712 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002713
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002714- Add -3 option to the interpreter to warn about features that are
2715 deprecated and will be changed/removed in Python 3.0.
2716
Georg Brandl2134e752007-05-21 20:34:16 +00002717- Patch #1686487: you can now pass any mapping after '**' in function
2718 calls.
2719
Collin Winter62903052007-05-18 23:11:24 +00002720- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002721 "except E as target:". This is to provide forwards compatibility
2722 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002723
Brett Cannon229cee22007-05-05 01:34:02 +00002724- Deprecate BaseException.message as per PEP 352.
2725
Georg Brandl3ee81df2008-05-17 18:14:43 +00002726- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002727 inherited from a builtin base.
2728
Vinay Sajip8549ce32007-05-06 17:53:37 +00002729- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002730 setting a plain string, ie don't expand to single letter identifiers.
2731
Raymond Hettinger13936692007-04-11 18:40:58 +00002732- Request #1191699: Slices can now be pickled.
2733
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002734- Request #1193128: str.translate() now allows a None argument for
2735 translations that only remove characters without re-mapping the
2736 remaining characters.
2737
Georg Brandl5cb76c12007-03-21 09:00:39 +00002738- Patch #1682205: a TypeError while unpacking an iterable is no longer
2739 masked by a generic one with the message "unpack non-sequence".
2740
Neal Norwitzaa754b72007-03-21 06:39:48 +00002741- Remove unused file Python/fmod.c.
2742
Guido van Rossum143b5642007-03-23 04:58:42 +00002743- Bug #1683368: The object.__init__() and object.__new__() methods are
2744 now stricter in rejecting excess arguments. The only time when
2745 either allows excess arguments is when it is not overridden and the
2746 other one is. For backwards compatibility, when both are
2747 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002748 warning later). Also, type.__init__() insists on the same signature
2749 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002750
Georg Brandl3ee81df2008-05-17 18:14:43 +00002751- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2752 object to complex using its __complex__() method before falling back
2753 to the __float__() method. Therefore, the functions in the cmath
2754 module now can operate on objects that define a __complex__()
2755 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002756
Georg Brandl3ee81df2008-05-17 18:14:43 +00002757- Patch #1623563: allow __class__ assignment for classes with
2758 __slots__. The old and the new class are still required to have the
2759 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002760

2765 ``object.__reduce_ex__()`` is called with an object that is faking
2766 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002767
Georg Brandl3ee81df2008-05-17 18:14:43 +00002768- Patch #1680015: Don't modify __slots__ tuple if it contains an

2772
Georg Brandl7b9c5552007-03-12 14:30:05 +00002773- Bug #1678647: write a newline after printing an exception in any
2774 case, even when converting the value to a string failed.
2775
Georg Brandl871f1bc2007-03-12 13:17:36 +00002776- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002777 its argument, if it exists. If not, it will work like before. This
2778 allows customizing the output of dir() in the presence of a
2779 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002780
Collin Winter276887b2007-03-12 16:11:39 +00002781- Patch #922167: Python no longer segfaults when faced with infinitely
2782 self-recursive reload() calls (as reported by bug #742342).
2783
Georg Brandl3ee81df2008-05-17 18:14:43 +00002784- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002787- Patch #1491866: change the complex() constructor to allow
2788 parthensized forms. This means complex(repr(x)) now works instead of
2789 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002790
Georg Brandlaa2321b2007-03-07 00:40:28 +00002791- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002792 makes the filenames the warning module prints much more sensible
2793 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002794
Georg Brandl49aafc92007-03-07 00:34:46 +00002795- Variant of patch #697613: don't exit the interpreter on a SystemExit
2796 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002797 variable is given, but break into the interactive interpreter just
2798 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002806- Patch #1674228: when assigning a slice (old-style), check for the
2807 sq_ass_slice instead of the sq_slice slot.
2808
Georg Brandl3ee81df2008-05-17 18:14:43 +00002809- When printing an unraisable error, don't print exceptions. before
2810 the name. This duplicates the behavior whening normally printing
2811 exceptions.

2868
Armin Rigo7ccbca92006-10-04 12:17:45 +00002869- A number of places, including integer negation and absolute value,

Georg Brandl5d59c092006-09-30 08:43:30 +00002876- Patch #1567691: super() and new.instancemethod() now don't accept

3438 incompatibility since it never made sense with ordinary subclasses
3439 -- the failure just occurred later, with a more cumbersome
3440 exception.

3654
Georg Brandl3ee81df2008-05-17 18:14:43 +00003655- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003721- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3722 with RFC 3207 and forgets any knowledge obtained from the server not
3723 obtained from the TLS negotiation itself. Patch contributed by Bill
3724 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003725
Georg Brandl3ee81df2008-05-17 18:14:43 +00003726- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003727 that the SMTP.starttls() caller no longer needs to call ehlo()
3728 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729 does not claim to support starttls. Adds the
3730 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3731 Fenner.

Georg Brandl56112892008-01-20 13:59:46 +00003768- Patch #1648: added ``sys.getprofile()`` and ``sys.gettrace()``.
3769
Georg Brandl3ee81df2008-05-17 18:14:43 +00003770- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00003785- itertools.chain() now has an alternate constructor,

3800 contents before adding elements from the iterable. This fix brings
3801 the behavior into line with that for list.__init__().

3811 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3812 silently miscode subclasses of those types. Now, it raises a
3813 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003814

Georg Brandl3ee81df2008-05-17 18:14:43 +00003829 time so that opening a database previously created with the DB_DUP
3830 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3831 opens. Specifically: dictionary assignment to a DB object will
3832 replace all values for a given key when the database allows
3833 duplicate values. DB users should use DB.put(k, v) when they want
3834 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003835

3841 characters with ASCII value less than 32. Also, it correctly quotes
3842 dots only if they occur on a single line, as opposed to the previous
3843 behavior of quoting dots if they are the second character of any
3844 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003845

4167-----
4168
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169- Unified naming convention for free lists and their limits. All free
4170 lists in Object/ are named ``free_list``, the counter ``numfree``
4171 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4172 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004173
Georg Brandl3ee81df2008-05-17 18:14:43 +00004174- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4175 to ``PyTuple_SetItem``, it can be used to populate a brand new
4176 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004177
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004178- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

4181 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4182 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004183
4184- Patch #1720595: add T_BOOL to the range of structmember types.
4185
4186- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4187 ``PyFloat_GetInfo()`` to the float API.
4188
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4190 of w# format code incorrectly truncated the length to an int, even
4191 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4192 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004193
Georg Brandl3ee81df2008-05-17 18:14:43 +00004194- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4195 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- PEP 3123: Provide forward compatibility with Python 3.0, while
4198 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4199 and PyVarObject_HEAD_INIT.

4202 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004203
4204- Patch #1733960: Allow T_LONGLONG to accept ints.

4211
4212- Fix some leftovers from the conversion from int to Py_ssize_t
4213 (relevant to strings and sequences of more than 2**31 items).
4214
4215- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4216 outside of pystate.c and should not be necessary.
4217
Georg Brandl3ee81df2008-05-17 18:14:43 +00004218- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4219 absolute imports. In earlier versions they might have used relative
4220 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004221
Georg Brandl3ee81df2008-05-17 18:14:43 +00004222- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4223 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004224
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004232- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4233 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4234 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4235 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004236

Georg Brandl3ee81df2008-05-17 18:14:43 +00004250- Removed the macfs module. It had been deprecated since Python 2.5.
4251 This lead to the deprecation of macostools.touched() as it relied
4252 solely on macfs and was a no-op under OS X.
