1007*Release date: 04-Dec-2008*
1008
1009Core and Builtins
1010-----------------
1011
1012- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1013 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1014 instead of throwing a MemoryError.
1015
1016- Issue #4367: Python would segfault during compiling when the unicodedata
1017 module couldn't be imported and \N escapes were present.
1018
1019- Issue #4348: Some bytearray methods returned that didn't cause any change to
1020 the bytearray, returned the same bytearray instead of a copy.
1021
1022- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1023
1024- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1025
1026- Issue #4048: The parser module now correctly validates relative imports.
1027
1028- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1032 method does not return iterators for the 4th and 5th items.
1033
1034- Issue #4209: Enabling unicode_literals and the print_function in the same
1035 __future__ import didn't work.
1036
1037- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1038 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1039 really executed because I cannot move to such directory on win2k)
1040
1041- Issue #4069: When set.remove(element) is used with a set element, the element
1042 is temporarily replaced with an equivalent frozenset. But the eventual
1043 KeyError would always report the empty frozenset([]) as the missing key. Now
1044 it correctly refers to the initial element.
1045
1046- Fixed C99 style comments in several files. Python is now C89 compatible
1047 again.

1195
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001196- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1197 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1198 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1199 ``printf`` function, whereas PyString_FromFormat has an independent
1200 implementation and uses "%zd" on all platforms for size_t values.
1201 This makes a difference on win64, where ``printf`` needs "%Id" to display
1202 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001204- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitrou0668c622008-08-26 22:42:08 +00001222 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1223 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1225 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1226 type object.

Benjamin Peterson37346b22008-08-23 20:27:43 +00001318Extension Modules
1319-----------------
1320
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001321- Issue #2975: When compiling several extension modules with Visual Studio 2008
1322 from the same python interpreter, some environment variables would grow
1323 without limit.
1324
Benjamin Peterson37346b22008-08-23 20:27:43 +00001325- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

1341 wrapper for warnings.catch_warnings() that makes it easier to check
1342 that expected warning messages are being reported.
1343

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001362What's New in Python 2.6 beta 3?
1363================================
1364
Barry Warsaw07a4a382008-08-21 01:15:08 +00001365*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001366
1367Core and Builtins
1368-----------------
1369
Guido van Rossumf8402962008-08-20 15:01:50 +00001370- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1371 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1372 extensions do not automatically benefit from the class attribute
1373 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1374 to their tp_flags field if they care. This is a backwards
1375 compatibility feature; in 3.0, all types will use the cache by
1376 default.
1377
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001378- Keyword arguments can now follow starred arguments. (``f(a, *args,
1379 keyword=23)`` is now valid syntax.)
1380
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001381- ctypes function pointers that are COM methods have a boolean True
1382 value again.
1383
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001384- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1385 by denying s# to parse objects that have a releasebuffer procedure,
1386 and introducing s*.
1387
Georg Brandl1e13ea92008-08-11 09:07:59 +00001388- Issue #3537: Fix an assertion failure when an empty but presized dict
1389 object was stored in the freelist.
1390
Mark Dickinsonb6467572008-08-04 21:30:09 +00001391- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1392 ValueError consistently across platforms.
1393
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001394- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1395 (64bit Unix, for example), unichr() would truncate its argument and return
1396 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1397
Neal Norwitze7d8be82008-07-31 17:17:14 +00001398- Apply security patches from Apple.
1399
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001400- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1401 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1402
Antoine Pitrou92f82162008-07-25 22:22:08 +00001403- Issue #1819: function calls with several named parameters are now on
1404 average 35% faster (as measured by pybench).
1405
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001406- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1407 the python debugger steps into a class statement: the free variables (local
1408 variables defined in an outer scope) would be deleted from the outer scope.
1409
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001410- Issue #2620: Overflow checking when allocating or reallocating memory
1411 was not always being done properly in some python types and extension
1412 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1413 all been updated to perform better checks and places in the code that
1414 would previously leak memory on the error path when such an allocation
1415 failed have been fixed.
1416
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001417Library
1418-------
1419
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001420- Issue #3612: Added some missing basic types in ctypes.wintypes.
1421
Benjamin Petersone977ad42008-08-20 01:42:01 +00001422- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1423 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1424
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001425- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1426 version reported by these tools does not necessarily follow the python
1427 version numbering scheme, so the module is less strict when parsing it.
1428
Nick Coghlanf70385a2008-08-18 12:42:46 +00001429- Issue #2235: Added Py3k warnings for types which will become unhashable
1430 under the stricter __hash__ inheritance rules in 3.0. Several types
1431 which did not meet the rules for hash invariants and were already
1432 unhashable in 3.0 have now been explicitly flagged as unhashable in
1433 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1434 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1435
Brett Cannon88f801d2008-08-18 00:46:22 +00001436- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1437 imported into the module but exposed as part of the module's API.
1438
Brett Cannon7b96f072008-08-18 00:41:11 +00001439- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1440
Brett Cannon46225e72008-08-18 00:36:52 +00001441- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1444
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001445- Issue #3575: Incremental decoder's decode function now takes bytearray
1446 by using 's*' instead of 't#'.
1447
Jesus Cea585ad8a2009-07-02 15:37:21 +00001448- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001449 fails unicode conversion on 2nd parameter. (windows only)
1450
Facundo Batista94f243a2008-08-17 03:38:39 +00001451- Issue 2464. urllib2 now supports a malformation in the URL received
1452 in a redirect.
1453
Brett Cannonabe423e2008-08-16 21:47:07 +00001454- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001455 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001456
Facundo Batistaeb90b782008-08-16 14:44:07 +00001457- Issue #2776: fixed small issue when handling an URL with double slash
1458 after a 302 response in the case of not going through a proxy.
1459
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001460- Issue #2676: in the email package, content-type parsing was hanging on
1461 pathological input because of quadratic or exponential behaviour of a
1462 regular expression.
1463
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001464- Issue #3476: binary buffered reading through the new "io" library is now
1465 thread-safe.
1466
Brett Cannonbf3157b2008-08-14 05:00:03 +00001467- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1468 since mimetools itself is deprecated. Because modules are cached, all
1469 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1470
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001471- Issue #3134: shutil referenced undefined WindowsError symbol.
1472
Robert Schuppenies14646332008-08-10 11:01:53 +00001473- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1474 menu entries were not deleted.
1475
Brett Cannon83e81842008-08-09 23:30:55 +00001476- Copied the implementation of reduce() to _functools.reduce() to have a
1477 version that did not raise a DeprecationWarning under -3.
1478
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001479- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1480 a MemoryError rather than silently stop the iteration.
1481
Guido van Rossum59ce9012008-08-09 14:55:34 +00001482- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1483 to _sre.compile() will now be rejected. This should not affect anybody
1484 since the re.compile() function never generates invalid re-bytecode.
1485
Skip Montanaroa032bf42008-08-08 22:52:51 +00001486- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1487 upon first access it can be automatically initialized from the csv file if
1488 it wasn't initialized during instantiation.
1489
Brett Cannon3aa2a492008-08-06 22:28:09 +00001490- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1491 the reload() built-in has been removed.
1492
Brett Cannon7e30b672008-08-04 21:52:25 +00001493- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001494 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1502 raised an AttributeError.
1503
Benjamin Peterson01a24322008-07-28 23:35:27 +00001504- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001505 asking for a specific length. This problem only affected files opened
1506 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001507
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001508- Issue #3449: Update decimal module to use most recent specification

1530
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001531- Issue #3394: zipfile.writestr sets external attributes when passed a
1532 file name rather than a ZipInfo instance, so files are extracted with
1533 mode 0600 rather than 000 under Unix.
1534
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001535- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1536 argument in python 2.5, this broke code that subclassed Popen to include its
1537 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001547- Issue #2235: the C API function PyObject_HashNotImplemented and its
1548 interaction with the tp_hash slot (added in 2.6b2) are now documented
1549

1551 coverage of the lookup process for special methods. The disclaimers
1552 regarding lack of coverage of new-style classes have also been
1553 removed, since the coverage is now fairly reasonable.

1558
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001559*Release date: 17-Jul-2008*

1562-----------------
1563
Georg Brandl3e483f62008-07-16 22:57:41 +00001564- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1565 its methods now allow for items objects that can be converted to
1566 an integer using operator.index().
1567
Mark Dickinson64b7e502008-07-16 09:40:03 +00001568- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1569 produced a ValueError instead of giving the correct float.
1570
Eric Smitha5fa5a22008-07-16 00:11:49 +00001571- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1572 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1573
Mark Dickinson7103aa42008-07-15 19:08:33 +00001574- Issue #3008: the float type has a new instance method 'float.hex'
1575 and a new class method 'float.fromhex' to convert floating-point
1576 numbers to and from hexadecimal strings, respectively.
1577
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001578- Issue #2235: __hash__ is once again inherited by default. To allow
1579 collections.Hashable to remain meaningful in the presence of the
1580 default hash implementation (object.__hash__), it is now possible
1581 to explicit block inheritance of hash by setting __hash__=None at
1582 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1583 level.
1584
Nick Coghlanb028f502008-07-13 14:52:36 +00001585- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1586 the parent module cannot be found while performing an absolute import.
1587 This means that an incorrectly defined __package__ attribute will
1588 now only prevent relative imports in that module rather than causing
1589 all imports from that module to fail.
1590
Nick Coghlan14ff9942008-07-08 14:21:42 +00001591- Issue #2517: Allow unicode messages in Exceptions again by correctly

1607 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

2111 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002124- Issue #1631171: Re-implement the 'warnings' module in C (the
2125 original Python code has been kept as backup). This will allow for
2126 using the 'warning's machinery in such places as the parser where
2127 use of pure Python code is not possible. Both the ``showarning()``
2128 and ``formatwarning()`` gain an optional 'line' argument which is
2129 not called by default for backwards-compatibility reasons. Setting
2130 ``warnings.showwarning()`` to an implementation that lacks support
2131 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002194- Issue #2550: The approach used by client/server code for obtaining
2195 ports to listen on in network-oriented tests has been refined in an
2196 effort to facilitate running multiple instances of the entire
2197 regression test suite in parallel without issue.
2198 test_support.bind_port() has been fixed such that it will always
2199 return a unique port -- which wasn't always the case with the
2200 previous implementation, especially if socket options had been set
2201 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2202 new implementation of bind_port() will actually raise an exception
2203 if it is passed an AF_INET/SOCK_STREAM socket with either the
2204 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2205 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2206 the socket it's been passed. This currently only applies to
2207 Windows. This option prevents any other sockets from binding to the
2208 host/port we've bound to, thus removing the possibility of the
2209 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2210 when a second SOCK_STREAM socket binds and accepts to a host/port
2211 that's already been bound by another socket. The optional preferred
2212 port parameter to bind_port() has been removed. Under no
2213 circumstances should tests be hard coding ports!
2214
2215 test_support.find_unused_port() has also been introduced, which will
2216 pass a temporary socket object to bind_port() in order to obtain an
2217 unused port. The temporary socket object is then closed and
2218 deleted, and the port is returned. This method should only be used
2219 for obtaining an unused port in order to pass to an external program
2220 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2221 a parameter to a server-oriented class that doesn't give you direct
2222 access to the underlying socket used.
2223
2224 Finally, test_support.HOST has been introduced, which should be used
2225 for the host argument of any relevant socket calls (i.e. bind and
2226 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002227
2228 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002229 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002230 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2231 test_asynchat and test_socket_ssl.
2232
Georg Brandl3ee81df2008-05-17 18:14:43 +00002233 It is now possible for multiple instances of the regression test
2234 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002418 optional: it defaults to the traceback of the exception that is
2419 currently being handled (is mandatory to be in the middle of an
2420 exception, otherwise it raises ValueError).

2437
Thomas Heller78b8f442008-03-05 14:53:39 +00002438- The bundled libffi copy is now in sync with the recently released
2439 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002440 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2441 files are used. On all linux systems the --with-system-ffi
2442 configure option defaults to "yes".

2501-----------------
2502
Fred Drakea8ee94b2008-03-01 02:45:07 +00002503- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002504 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002505
Georg Brandlad61bc82008-02-23 15:11:18 +00002506- Issue #2067: file.__exit__() now calls subclasses' close() method.
2507
2508- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002509
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002510- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002511 issue 215555 for a discussion.
2512
Eric Smitha73fbe72008-02-23 03:09:44 +00002513- Added the future_builtins module, which contains hex() and oct().
2514 These are the PEP 3127 version of these functions, designed to be
2515 compatible with the hex() and oct() builtins from Python 3.0. They
2516 differ slightly in their output formats from the existing, unchanged
2517 Python 2.6 builtins. The expected usage of the future_builtins
2518 module is:
2519 from future_builtins import hex, oct
2520
Eric Smith7ef40bf2008-02-20 23:34:22 +00002521- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2522 exponents for exponents with absolute value < 100. Follows C99
2523 standard. This is a change on Windows, which would use 3 digits.
2524 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2525 so that any alterations it does to the resulting string will be
2526 available in stringlib/formatter.h (for float.__format__).
2527
Eric Smith5a3c1352008-02-19 13:21:56 +00002528- Implemented PEP 3101, Advanced String Formatting. This adds a new
2529 builtin format(); a format() method for str and unicode; a
2530 __format__() method to object, str, unicode, int, long, float, and
2531 datetime; the class string.Formatter; and the C API
2532 PyObject_Format().
2533
Georg Brandl3ee81df2008-05-17 18:14:43 +00002534- Fixed several potential crashes, all caused by specially crafted
2535 __del__ methods exploiting objects in temporarily inconsistent
2536 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002537
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002538- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002539 prevent a possible crash: an Abstract Base Class would try to access
2540 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002541
Georg Brandl3ee81df2008-05-17 18:14:43 +00002542- Fixed repr() and str() of complex numbers with infinity or nan as
2543 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002544
Georg Brandl3ee81df2008-05-17 18:14:43 +00002545- Clear all free lists during a gc.collect() of the highest generation
2546 in order to allow pymalloc to free more arenas. Python may give back
2547 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002548
Georg Brandl3ee81df2008-05-17 18:14:43 +00002549- Issue #2045: Fix an infinite recursion triggered when printing a
2550 subclass of collections.defaultdict, if its default_factory is set
2551 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002552
Christian Heimesf75dbef2008-02-08 00:11:31 +00002553- Fixed a minor memory leak in dictobject.c. The content of the free
2554 list was not freed on interpreter shutdown.
2555
Georg Brandl3ee81df2008-05-17 18:14:43 +00002556- Limit free list of method and builtin function objects to 256
2557 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002558
Georg Brandl3ee81df2008-05-17 18:14:43 +00002559- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2560 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002561 to compact the internal free lists of pre-allocted ints and floats.
2562
Georg Brandl3ee81df2008-05-17 18:14:43 +00002563- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2564 calls. Python expected the return type int but the fork familie
2565 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002566
Georg Brandl3ee81df2008-05-17 18:14:43 +00002567- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2568 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002569
Georg Brandl3ee81df2008-05-17 18:14:43 +00002570- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2571 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002572

Georg Brandl3ee81df2008-05-17 18:14:43 +00002576- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2577 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002578
Georg Brandl3ee81df2008-05-17 18:14:43 +00002579- Patch #1473257: generator objects gain a gi_code attribute. This is
2580 the same object as the func_code attribute of the function that
2581 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002582
Georg Brandl3ee81df2008-05-17 18:14:43 +00002583- Issue #1920: "while 0" statements were completely removed by the
2584 compiler, even in the presence of an "else" clause, which is
2585 supposed to be run when the condition is false. Now the compiler
2586 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002587
Guido van Rossumeead05f2008-01-24 18:21:02 +00002588- A few crashers fixed: weakref_in_del.py (issue #1377858);
2589 loosing_dict_ref.py (issue #1303614, test67.py);
2590 borrowed_ref_[34].py (not in tracker).
2591
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002592- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002593 suppressed while an extension is loaded by calling SetErrorMode in
2594 dynload_win.c. The error is still reported properly.
2595
Georg Brandl3ee81df2008-05-17 18:14:43 +00002596- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002597 several extension methods and modules do not work without unicode
2598 support.
2599
Georg Brandl26543b12008-01-21 18:36:51 +00002600- Issue #1882: when compiling code from a string, encoding cookies in the
2601 second line of code were not always recognized correctly.
2602
Georg Brandl14404b62008-01-19 19:27:05 +00002603- Issue #1679: "0x" was taken as a valid integer literal.
2604
Georg Brandl6caad7d2008-01-26 14:19:22 +00002605- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002606 added.
2607
Christian Heimesc94e2b52008-01-14 04:13:37 +00002608- sys.float_info / PyFloat_GetInfo: The floating point information
2609 object was converted from a dict to a specialized structseq object.
2610
Georg Brandl3ee81df2008-05-17 18:14:43 +00002611- Patch #1816: Added sys.flags structseq. It exposes the status of
2612 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002613
Georg Brandl3ee81df2008-05-17 18:14:43 +00002614- Objects/structseq.c: Implemented new structseq representation. The
2615 patch makes structseqs (e.g. the return value of os.stat) more
2616 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002617
Georg Brandl3ee81df2008-05-17 18:14:43 +00002618- Patch #1700288: added a type attribute cache that caches method

2627 envvar and sys.dont_write_bytecode attribute. All these can be set
2628 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002629
Georg Brandl3ee81df2008-05-17 18:14:43 +00002630- Improve some exception messages when Windows fails to load an
2631 extension module. Now we get for example '%1 is not a valid Win32
2632 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002633

Christian Heimes0a8143f2007-12-18 23:22:54 +00002639- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002640 and INF. float("nan"), float("inf") and float("-inf") now work on
2641 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002642
Georg Brandl3ee81df2008-05-17 18:14:43 +00002643- Compiler now generates simpler and faster code for dictionary
2644 literals. The oparg for BUILD_MAP now indicates an estimated
2645 dictionary size. There is a new opcode, STORE_MAP, for adding
2646 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002675- Patch #1739468: Directories and zipfiles containing a __main__.py
2676 file can now be directly executed by passing their name to the
2677 interpreter. The directory/zipfile is automatically inserted as the
2678 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002680- Issue #1265: Fix a problem with sys.settrace, if the tracing
2681 function uses a generator expression when at the same time the
2682 executed code is closing a paused generator.

2689
Georg Brandl3ee81df2008-05-17 18:14:43 +00002690- The enumerate() builtin function is no longer bounded to sequences
2691 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2692 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002693
Georg Brandl3ee81df2008-05-17 18:14:43 +00002694- Issue #1686386: Tuple's tp_repr did not take into account the
2695 possibility of having a self-referential tuple, which is possible
2696 from C code. Nor did object's tp_str consider that a type's tp_str
2697 could do something that could lead to an inifinite recursion.
2698 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2699 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002700
Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Issue #1164: It was possible to trigger deadlock when using the
2702 'print' statement to write to a file since the GIL was not released
2703 as needed. Now PyObject_Print() does the right thing along with
2704 various tp_print implementations of the built-in types and those in
2705 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002707- Issue #1147: Exceptions were directly allowing string exceptions in

2709 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00002713
Brett Cannon1e534b52007-09-07 04:18:30 +00002714- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002715 PyObject_Call() never calling back out to Python code to trigger
2716 recursion depth updates/checks. Required the creation of a static
2717 RuntimeError instance in case normalizing an exception put the
2718 recursion check value past its limit. Fixes crashers
2719 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002734- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002735 __*__ attributes. (Some already existed, e.g., __doc__ and
2736 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002737
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002738- Add -3 option to the interpreter to warn about features that are
2739 deprecated and will be changed/removed in Python 3.0.
2740
Georg Brandl2134e752007-05-21 20:34:16 +00002741- Patch #1686487: you can now pass any mapping after '**' in function
2742 calls.
2743
Collin Winter62903052007-05-18 23:11:24 +00002744- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002745 "except E as target:". This is to provide forwards compatibility
2746 with Python 3.0.

2752
Vinay Sajip8549ce32007-05-06 17:53:37 +00002753- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002754 setting a plain string, ie don't expand to single letter identifiers.
2755
Raymond Hettinger13936692007-04-11 18:40:58 +00002756- Request #1191699: Slices can now be pickled.
2757
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002758- Request #1193128: str.translate() now allows a None argument for
2759 translations that only remove characters without re-mapping the
2760 remaining characters.
2761
Georg Brandl5cb76c12007-03-21 09:00:39 +00002762- Patch #1682205: a TypeError while unpacking an iterable is no longer

2764
Neal Norwitzaa754b72007-03-21 06:39:48 +00002765- Remove unused file Python/fmod.c.
2766
Guido van Rossum143b5642007-03-23 04:58:42 +00002767- Bug #1683368: The object.__init__() and object.__new__() methods are
2768 now stricter in rejecting excess arguments. The only time when
2769 either allows excess arguments is when it is not overridden and the
2770 other one is. For backwards compatibility, when both are
2771 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002772 warning later). Also, type.__init__() insists on the same signature
2773 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002774
Georg Brandl3ee81df2008-05-17 18:14:43 +00002775- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2776 object to complex using its __complex__() method before falling back
2777 to the __float__() method. Therefore, the functions in the cmath
2778 module now can operate on objects that define a __complex__()
2779 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002780
Georg Brandl3ee81df2008-05-17 18:14:43 +00002781- Patch #1623563: allow __class__ assignment for classes with
2782 __slots__. The old and the new class are still required to have the
2783 same slot names.

2789 ``object.__reduce_ex__()`` is called with an object that is faking
2790 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002791
Georg Brandl3ee81df2008-05-17 18:14:43 +00002792- Patch #1680015: Don't modify __slots__ tuple if it contains an

2796
Georg Brandl7b9c5552007-03-12 14:30:05 +00002797- Bug #1678647: write a newline after printing an exception in any
2798 case, even when converting the value to a string failed.
2799
Georg Brandl871f1bc2007-03-12 13:17:36 +00002800- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002801 its argument, if it exists. If not, it will work like before. This
2802 allows customizing the output of dir() in the presence of a
2803 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00002805- Patch #922167: Python no longer segfaults when faced with infinitely
2806 self-recursive reload() calls (as reported by bug #742342).
2807
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002811- Patch #1491866: change the complex() constructor to allow
2812 parthensized forms. This means complex(repr(x)) now works instead of
2813 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002814
Georg Brandlaa2321b2007-03-07 00:40:28 +00002815- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002816 makes the filenames the warning module prints much more sensible
2817 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002818

Georg Brandl0fca97a2007-03-05 22:28:08 +00002830- Patch #1674228: when assigning a slice (old-style), check for the
2831 sq_ass_slice instead of the sq_slice slot.
2832
Georg Brandl3ee81df2008-05-17 18:14:43 +00002833- When printing an unraisable error, don't print exceptions. before
2834 the name. This duplicates the behavior whening normally printing
2835 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002836
Georg Brandl3ee81df2008-05-17 18:14:43 +00002837- Bug #1653736: Properly discard third argument to

2892
Armin Rigo7ccbca92006-10-04 12:17:45 +00002893- A number of places, including integer negation and absolute value,

Georg Brandl3ee81df2008-05-17 18:14:43 +00003403 are set for invalid interpolation sequences that would lead to

3460 TestCase and TestSuite subclasses (not instances) are no longer
3461 accepted in TestSuite.addTest(). This should cause no

3463 -- the failure just occurred later, with a more cumbersome
3464 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003745- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3746 with RFC 3207 and forgets any knowledge obtained from the server not
3747 obtained from the TLS negotiation itself. Patch contributed by Bill
3748 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003749
Georg Brandl3ee81df2008-05-17 18:14:43 +00003750- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003751 that the SMTP.starttls() caller no longer needs to call ehlo()
3752 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003753 does not claim to support starttls. Adds the
3754 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3835 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3836 silently miscode subclasses of those types. Now, it raises a
3837 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003838

Georg Brandl3ee81df2008-05-17 18:14:43 +00003853 time so that opening a database previously created with the DB_DUP
3854 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3855 opens. Specifically: dictionary assignment to a DB object will
3856 replace all values for a given key when the database allows
3857 duplicate values. DB users should use DB.put(k, v) when they want
3858 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003859

3865 characters with ASCII value less than 32. Also, it correctly quotes
3866 dots only if they occur on a single line, as opposed to the previous
3867 behavior of quoting dots if they are the second character of any
3868 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003869

4133 without this option!
4134
Martin v. Löwis63bf1492007-11-12 05:14:05 +00004135- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
4136
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004137- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138 periodic threadstate and signal checking in tight loops. By
4139 default, this option is turned-off. It should only be enabled in
4140 debugged, performance critical applications.

4156 returned by python-config if Python was built with --enable-shared
4157 because that prevented the shared library from being used.

4191-----
4192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Unified naming convention for free lists and their limits. All free
4194 lists in Object/ are named ``free_list``, the counter ``numfree``
4195 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4196 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004197
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4199 to ``PyTuple_SetItem``, it can be used to populate a brand new
4200 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004201
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004202- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

4209
4210- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4211 ``PyFloat_GetInfo()`` to the float API.
4212
Georg Brandl3ee81df2008-05-17 18:14:43 +00004213- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4214 of w# format code incorrectly truncated the length to an int, even
4215 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4216 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004217
Georg Brandl3ee81df2008-05-17 18:14:43 +00004218- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4236- Fix some leftovers from the conversion from int to Py_ssize_t
4237 (relevant to strings and sequences of more than 2**31 items).
4238
4239- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4240 outside of pystate.c and should not be necessary.
4241
Georg Brandl3ee81df2008-05-17 18:14:43 +00004242- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4243 absolute imports. In earlier versions they might have used relative
4244 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004245
Georg Brandl3ee81df2008-05-17 18:14:43 +00004246- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4247 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004248
Georg Brandl3ee81df2008-05-17 18:14:43 +00004249- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4257 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4258 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4259 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004260

Georg Brandl3ee81df2008-05-17 18:14:43 +00004274- Removed the macfs module. It had been deprecated since Python 2.5.
4275 This lead to the deprecation of macostools.touched() as it relied
4276 solely on macfs and was a no-op under OS X.
