1020What's New in Python 2.6.1
1021==========================
1022
1023*Release date: 04-Dec-2008*
1024
1025Core and Builtins
1026-----------------
1027
1028- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1029 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1030 instead of throwing a MemoryError.
1031
1032- Issue #4367: Python would segfault during compiling when the unicodedata
1033 module couldn't be imported and \N escapes were present.
1034
1035- Issue #4348: Some bytearray methods returned that didn't cause any change to
1036 the bytearray, returned the same bytearray instead of a copy.
1037
1038- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1039
1040- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1041
1042- Issue #4048: The parser module now correctly validates relative imports.
1043
1044- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1045 exec statement.

1047- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1048 method does not return iterators for the 4th and 5th items.
1049
1050- Issue #4209: Enabling unicode_literals and the print_function in the same
1051 __future__ import didn't work.
1052
1053- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1054 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1055 really executed because I cannot move to such directory on win2k)
1056
1057- Issue #4069: When set.remove(element) is used with a set element, the element
1058 is temporarily replaced with an equivalent frozenset. But the eventual
1059 KeyError would always report the empty frozenset([]) as the missing key. Now
1060 it correctly refers to the initial element.
1061
1062- Fixed C99 style comments in several files. Python is now C89 compatible
1063 again.

1211
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001212- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1213 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1214 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1215 ``printf`` function, whereas PyString_FromFormat has an independent
1216 implementation and uses "%zd" on all platforms for size_t values.
1217 This makes a difference on win64, where ``printf`` needs "%Id" to display
1218 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001220- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitrou0668c622008-08-26 22:42:08 +00001238 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1239 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1241 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1242 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00001312- Issue 3602: Moved test.test_support.catch_warning() to
1313 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1314 for catch_warnings() also led to an improvement in the raising of a
1315 DeprecationWarning related to warnings.warn_explicit().
1316

1336
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001337- Issue #2975: When compiling several extension modules with Visual Studio 2008
1338 from the same python interpreter, some environment variables would grow
1339 without limit.
1340
Benjamin Peterson37346b22008-08-23 20:27:43 +00001341- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1342 exploitation of poor argument checking.
1343
Gerhard Häringef2276b2008-09-12 13:54:06 +00001344- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001378What's New in Python 2.6 beta 3?
1379================================
1380
Barry Warsaw07a4a382008-08-21 01:15:08 +00001381*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001382
1383Core and Builtins
1384-----------------
1385
Guido van Rossumf8402962008-08-20 15:01:50 +00001386- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1387 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1388 extensions do not automatically benefit from the class attribute
1389 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1390 to their tp_flags field if they care. This is a backwards
1391 compatibility feature; in 3.0, all types will use the cache by
1392 default.
1393
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001394- Keyword arguments can now follow starred arguments. (``f(a, *args,
1395 keyword=23)`` is now valid syntax.)
1396
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001397- ctypes function pointers that are COM methods have a boolean True
1398 value again.
1399
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001400- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1401 by denying s# to parse objects that have a releasebuffer procedure,
1402 and introducing s*.
1403
Georg Brandl1e13ea92008-08-11 09:07:59 +00001404- Issue #3537: Fix an assertion failure when an empty but presized dict
1405 object was stored in the freelist.
1406
Mark Dickinsonb6467572008-08-04 21:30:09 +00001407- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1408 ValueError consistently across platforms.
1409
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001410- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1411 (64bit Unix, for example), unichr() would truncate its argument and return
1412 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1413
Neal Norwitze7d8be82008-07-31 17:17:14 +00001414- Apply security patches from Apple.
1415
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001416- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1417 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1418
Antoine Pitrou92f82162008-07-25 22:22:08 +00001419- Issue #1819: function calls with several named parameters are now on
1420 average 35% faster (as measured by pybench).
1421
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001422- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1423 the python debugger steps into a class statement: the free variables (local
1424 variables defined in an outer scope) would be deleted from the outer scope.
1425
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001426- Issue #2620: Overflow checking when allocating or reallocating memory
1427 was not always being done properly in some python types and extension
1428 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1429 all been updated to perform better checks and places in the code that
1430 would previously leak memory on the error path when such an allocation
1431 failed have been fixed.
1432
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001433Library
1434-------
1435

1437
Benjamin Petersone977ad42008-08-20 01:42:01 +00001438- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1439 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1440
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001441- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1442 version reported by these tools does not necessarily follow the python
1443 version numbering scheme, so the module is less strict when parsing it.
1444
Nick Coghlanf70385a2008-08-18 12:42:46 +00001445- Issue #2235: Added Py3k warnings for types which will become unhashable
1446 under the stricter __hash__ inheritance rules in 3.0. Several types
1447 which did not meet the rules for hash invariants and were already
1448 unhashable in 3.0 have now been explicitly flagged as unhashable in
1449 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1450 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1451
Brett Cannon88f801d2008-08-18 00:46:22 +00001452- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1456
Brett Cannon46225e72008-08-18 00:36:52 +00001457- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1460
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001461- Issue #3575: Incremental decoder's decode function now takes bytearray
1462 by using 's*' instead of 't#'.
1463
Jesus Cea585ad8a2009-07-02 15:37:21 +00001464- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001465 fails unicode conversion on 2nd parameter. (windows only)
1466
Facundo Batista94f243a2008-08-17 03:38:39 +00001467- Issue 2464. urllib2 now supports a malformation in the URL received
1468 in a redirect.
1469
Brett Cannonabe423e2008-08-16 21:47:07 +00001470- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001471 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001472
Facundo Batistaeb90b782008-08-16 14:44:07 +00001473- Issue #2776: fixed small issue when handling an URL with double slash
1474 after a 302 response in the case of not going through a proxy.
1475
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001476- Issue #2676: in the email package, content-type parsing was hanging on
1477 pathological input because of quadratic or exponential behaviour of a
1478 regular expression.
1479
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001480- Issue #3476: binary buffered reading through the new "io" library is now
1481 thread-safe.
1482
Brett Cannonbf3157b2008-08-14 05:00:03 +00001483- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1484 since mimetools itself is deprecated. Because modules are cached, all
1485 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1486
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001487- Issue #3134: shutil referenced undefined WindowsError symbol.
1488
Robert Schuppenies14646332008-08-10 11:01:53 +00001489- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1490 menu entries were not deleted.
1491
Brett Cannon83e81842008-08-09 23:30:55 +00001492- Copied the implementation of reduce() to _functools.reduce() to have a
1493 version that did not raise a DeprecationWarning under -3.
1494
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001495- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1496 a MemoryError rather than silently stop the iteration.
1497
Guido van Rossum59ce9012008-08-09 14:55:34 +00001498- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1499 to _sre.compile() will now be rejected. This should not affect anybody
1500 since the re.compile() function never generates invalid re-bytecode.
1501
Skip Montanaroa032bf42008-08-08 22:52:51 +00001502- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00001506- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1507 the reload() built-in has been removed.
1508
Brett Cannon7e30b672008-08-04 21:52:25 +00001509- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001510 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001521 asking for a specific length. This problem only affected files opened
1522 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001523

1549 mode 0600 rather than 000 under Unix.
1550
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001551- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1583
Mark Dickinson64b7e502008-07-16 09:40:03 +00001584- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1585 produced a ValueError instead of giving the correct float.
1586
Eric Smitha5fa5a22008-07-16 00:11:49 +00001587- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1588 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1589
Mark Dickinson7103aa42008-07-15 19:08:33 +00001590- Issue #3008: the float type has a new instance method 'float.hex'

1596 default hash implementation (object.__hash__), it is now possible
1597 to explicit block inheritance of hash by setting __hash__=None at
1598 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1599 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00001601- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1602 the parent module cannot be found while performing an absolute import.
1603 This means that an incorrectly defined __package__ attribute will
1604 now only prevent relative imports in that module rather than causing
1605 all imports from that module to fail.

1618
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001619- Issue #3004: Minor change to slice.indices(): the start and stop
1620 arguments are now treated identically, making the behaviour easier
1621 to describe and understand. For example, slice(None, -10,
1622 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1623 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1624 10, -1).

1667 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001668 wrong because the actual transmitted size could differ from the

2127 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00002128
Christian Heimese74c8f22008-04-19 02:23:57 +00002129- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002140- Issue #1631171: Re-implement the 'warnings' module in C (the
2141 original Python code has been kept as backup). This will allow for
2142 using the 'warning's machinery in such places as the parser where
2143 use of pure Python code is not possible. Both the ``showarning()``
2144 and ``formatwarning()`` gain an optional 'line' argument which is
2145 not called by default for backwards-compatibility reasons. Setting
2146 ``warnings.showwarning()`` to an implementation that lacks support
2147 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002210- Issue #2550: The approach used by client/server code for obtaining
2211 ports to listen on in network-oriented tests has been refined in an
2212 effort to facilitate running multiple instances of the entire
2213 regression test suite in parallel without issue.
2214 test_support.bind_port() has been fixed such that it will always
2215 return a unique port -- which wasn't always the case with the
2216 previous implementation, especially if socket options had been set
2217 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2218 new implementation of bind_port() will actually raise an exception
2219 if it is passed an AF_INET/SOCK_STREAM socket with either the
2220 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2221 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2222 the socket it's been passed. This currently only applies to
2223 Windows. This option prevents any other sockets from binding to the
2224 host/port we've bound to, thus removing the possibility of the
2225 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2226 when a second SOCK_STREAM socket binds and accepts to a host/port
2227 that's already been bound by another socket. The optional preferred
2228 port parameter to bind_port() has been removed. Under no
2229 circumstances should tests be hard coding ports!
2230
2231 test_support.find_unused_port() has also been introduced, which will
2232 pass a temporary socket object to bind_port() in order to obtain an
2233 unused port. The temporary socket object is then closed and
2234 deleted, and the port is returned. This method should only be used
2235 for obtaining an unused port in order to pass to an external program
2236 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2237 a parameter to a server-oriented class that doesn't give you direct
2238 access to the underlying socket used.
2239
2240 Finally, test_support.HOST has been introduced, which should be used
2241 for the host argument of any relevant socket calls (i.e. bind and
2242 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002243
2244 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002246 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2247 test_asynchat and test_socket_ssl.
2248
Georg Brandl3ee81df2008-05-17 18:14:43 +00002249 It is now possible for multiple instances of the regression test
2250 suite to run in parallel without issue.

2517-----------------
2518
Fred Drakea8ee94b2008-03-01 02:45:07 +00002519- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002520 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002521
Georg Brandlad61bc82008-02-23 15:11:18 +00002522- Issue #2067: file.__exit__() now calls subclasses' close() method.
2523
2524- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002525
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002526- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002527 issue 215555 for a discussion.
2528
Eric Smitha73fbe72008-02-23 03:09:44 +00002529- Added the future_builtins module, which contains hex() and oct().
2530 These are the PEP 3127 version of these functions, designed to be
2531 compatible with the hex() and oct() builtins from Python 3.0. They
2532 differ slightly in their output formats from the existing, unchanged
2533 Python 2.6 builtins. The expected usage of the future_builtins
2534 module is:
2535 from future_builtins import hex, oct
2536
Eric Smith7ef40bf2008-02-20 23:34:22 +00002537- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2538 exponents for exponents with absolute value < 100. Follows C99
2539 standard. This is a change on Windows, which would use 3 digits.
2540 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2541 so that any alterations it does to the resulting string will be
2542 available in stringlib/formatter.h (for float.__format__).
2543
Eric Smith5a3c1352008-02-19 13:21:56 +00002544- Implemented PEP 3101, Advanced String Formatting. This adds a new
2545 builtin format(); a format() method for str and unicode; a
2546 __format__() method to object, str, unicode, int, long, float, and
2547 datetime; the class string.Formatter; and the C API
2548 PyObject_Format().
2549
Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Fixed several potential crashes, all caused by specially crafted
2551 __del__ methods exploiting objects in temporarily inconsistent
2552 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002553
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002554- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555 prevent a possible crash: an Abstract Base Class would try to access
2556 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002557
Georg Brandl3ee81df2008-05-17 18:14:43 +00002558- Fixed repr() and str() of complex numbers with infinity or nan as
2559 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002561- Clear all free lists during a gc.collect() of the highest generation
2562 in order to allow pymalloc to free more arenas. Python may give back
2563 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002564
Georg Brandl3ee81df2008-05-17 18:14:43 +00002565- Issue #2045: Fix an infinite recursion triggered when printing a
2566 subclass of collections.defaultdict, if its default_factory is set
2567 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002568
Christian Heimesf75dbef2008-02-08 00:11:31 +00002569- Fixed a minor memory leak in dictobject.c. The content of the free
2570 list was not freed on interpreter shutdown.
2571
Georg Brandl3ee81df2008-05-17 18:14:43 +00002572- Limit free list of method and builtin function objects to 256
2573 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002574
Georg Brandl3ee81df2008-05-17 18:14:43 +00002575- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2576 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002577 to compact the internal free lists of pre-allocted ints and floats.
2578
Georg Brandl3ee81df2008-05-17 18:14:43 +00002579- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2580 calls. Python expected the return type int but the fork familie
2581 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002582
Georg Brandl3ee81df2008-05-17 18:14:43 +00002583- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2584 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002585
Georg Brandl3ee81df2008-05-17 18:14:43 +00002586- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2587 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002592- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2593 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002594
Georg Brandl3ee81df2008-05-17 18:14:43 +00002595- Patch #1473257: generator objects gain a gi_code attribute. This is
2596 the same object as the func_code attribute of the function that
2597 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002598
Georg Brandl3ee81df2008-05-17 18:14:43 +00002599- Issue #1920: "while 0" statements were completely removed by the
2600 compiler, even in the presence of an "else" clause, which is
2601 supposed to be run when the condition is false. Now the compiler
2602 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002603
Guido van Rossumeead05f2008-01-24 18:21:02 +00002604- A few crashers fixed: weakref_in_del.py (issue #1377858);
2605 loosing_dict_ref.py (issue #1303614, test67.py);
2606 borrowed_ref_[34].py (not in tracker).
2607
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002608- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002609 suppressed while an extension is loaded by calling SetErrorMode in
2610 dynload_win.c. The error is still reported properly.
2611
Georg Brandl3ee81df2008-05-17 18:14:43 +00002612- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002613 several extension methods and modules do not work without unicode
2614 support.
2615
Georg Brandl26543b12008-01-21 18:36:51 +00002616- Issue #1882: when compiling code from a string, encoding cookies in the
2617 second line of code were not always recognized correctly.
2618
Georg Brandl14404b62008-01-19 19:27:05 +00002619- Issue #1679: "0x" was taken as a valid integer literal.
2620
Georg Brandl6caad7d2008-01-26 14:19:22 +00002621- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002622 added.
2623
Christian Heimesc94e2b52008-01-14 04:13:37 +00002624- sys.float_info / PyFloat_GetInfo: The floating point information
2625 object was converted from a dict to a specialized structseq object.
2626
Georg Brandl3ee81df2008-05-17 18:14:43 +00002627- Patch #1816: Added sys.flags structseq. It exposes the status of
2628 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002629
Georg Brandl3ee81df2008-05-17 18:14:43 +00002630- Objects/structseq.c: Implemented new structseq representation. The
2631 patch makes structseqs (e.g. the return value of os.stat) more
2632 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002633
Georg Brandl3ee81df2008-05-17 18:14:43 +00002634- Patch #1700288: added a type attribute cache that caches method
2635 accesses, resulting in speedups in heavily object-oriented code.

2643 envvar and sys.dont_write_bytecode attribute. All these can be set
2644 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002645
Georg Brandl3ee81df2008-05-17 18:14:43 +00002646- Improve some exception messages when Windows fails to load an
2647 extension module. Now we get for example '%1 is not a valid Win32
2648 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002649

2653 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002654
Christian Heimes0a8143f2007-12-18 23:22:54 +00002655- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002656 and INF. float("nan"), float("inf") and float("-inf") now work on
2657 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002658
Georg Brandl3ee81df2008-05-17 18:14:43 +00002659- Compiler now generates simpler and faster code for dictionary
2660 literals. The oparg for BUILD_MAP now indicates an estimated

Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- The enumerate() builtin function is no longer bounded to sequences

Georg Brandl3ee81df2008-05-17 18:14:43 +00002710- Issue #1686386: Tuple's tp_repr did not take into account the
2711 possibility of having a self-referential tuple, which is possible
2712 from C code. Nor did object's tp_str consider that a type's tp_str
2713 could do something that could lead to an inifinite recursion.
2714 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2715 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002731 PyObject_Call() never calling back out to Python code to trigger
2732 recursion depth updates/checks. Required the creation of a static

2762 with Python 3.0.

2782
Guido van Rossum143b5642007-03-23 04:58:42 +00002783- Bug #1683368: The object.__init__() and object.__new__() methods are
2784 now stricter in rejecting excess arguments. The only time when
2785 either allows excess arguments is when it is not overridden and the
2786 other one is. For backwards compatibility, when both are
2787 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002788 warning later). Also, type.__init__() insists on the same signature
2789 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002791- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2792 object to complex using its __complex__() method before falling back
2793 to the __float__() method. Therefore, the functions in the cmath
2794 module now can operate on objects that define a __complex__()
2795 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00002813- Bug #1678647: write a newline after printing an exception in any
2814 case, even when converting the value to a string failed.
2815
Georg Brandl871f1bc2007-03-12 13:17:36 +00002816- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002817 its argument, if it exists. If not, it will work like before. This
2818 allows customizing the output of dir() in the presence of a
2819 __getattr__().

2829 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002830
Georg Brandlaa2321b2007-03-07 00:40:28 +00002831- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002832 makes the filenames the warning module prints much more sensible
2833 when a PYTHONSTARTUP file is used.

2848
Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- When printing an unraisable error, don't print exceptions. before

Georg Brandl92a6bae2007-03-13 17:43:32 +00003418- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003419 are set for invalid interpolation sequences that would lead to

3476 TestCase and TestSuite subclasses (not instances) are no longer
3477 accepted in TestSuite.addTest(). This should cause no

3479 -- the failure just occurred later, with a more cumbersome
3480 exception.

3763 obtained from the TLS negotiation itself. Patch contributed by Bill
3764 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003765
Georg Brandl3ee81df2008-05-17 18:14:43 +00003766- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003767 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00003769 does not claim to support starttls. Adds the
3770 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00003854

Georg Brandl3ee81df2008-05-17 18:14:43 +00003869 time so that opening a database previously created with the DB_DUP
3870 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3871 opens. Specifically: dictionary assignment to a DB object will
3872 replace all values for a given key when the database allows
3873 duplicate values. DB users should use DB.put(k, v) when they want
3874 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003875

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004153- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004154 periodic threadstate and signal checking in tight loops. By
4155 default, this option is turned-off. It should only be enabled in
4156 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004157

4207-----
4208
Georg Brandl3ee81df2008-05-17 18:14:43 +00004209- Unified naming convention for free lists and their limits. All free
4210 lists in Object/ are named ``free_list``, the counter ``numfree``
4211 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4212 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004213
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4215 to ``PyTuple_SetItem``, it can be used to populate a brand new
4216 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004217

4228
Georg Brandl3ee81df2008-05-17 18:14:43 +00004229- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4230 of w# format code incorrectly truncated the length to an int, even
4231 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4232 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004233
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4252- Fix some leftovers from the conversion from int to Py_ssize_t
4253 (relevant to strings and sequences of more than 2**31 items).
4254
4255- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4256 outside of pystate.c and should not be necessary.
4257
Georg Brandl3ee81df2008-05-17 18:14:43 +00004258- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4259 absolute imports. In earlier versions they might have used relative
4260 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004261
Georg Brandl3ee81df2008-05-17 18:14:43 +00004262- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4263 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004264
Georg Brandl3ee81df2008-05-17 18:14:43 +00004265- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004290- Removed the macfs module. It had been deprecated since Python 2.5.
4291 This lead to the deprecation of macostools.touched() as it relied
4292 solely on macfs and was a no-op under OS X.
