1000What's New in Python 2.6.1
1001==========================
1002
1003*Release date: 04-Dec-2008*
1004
1005Core and Builtins
1006-----------------
1007
1008- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1009 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1010 instead of throwing a MemoryError.
1011
1012- Issue #4367: Python would segfault during compiling when the unicodedata
1013 module couldn't be imported and \N escapes were present.
1014
1015- Issue #4348: Some bytearray methods returned that didn't cause any change to
1016 the bytearray, returned the same bytearray instead of a copy.
1017
1018- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1019
1020- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1021
1022- Issue #4048: The parser module now correctly validates relative imports.
1023
1024- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1025 exec statement.
1026
1027- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1028 method does not return iterators for the 4th and 5th items.
1029
1030- Issue #4209: Enabling unicode_literals and the print_function in the same
1031 __future__ import didn't work.
1032
1033- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1034 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1035 really executed because I cannot move to such directory on win2k)
1036
1037- Issue #4069: When set.remove(element) is used with a set element, the element
1038 is temporarily replaced with an equivalent frozenset. But the eventual
1039 KeyError would always report the empty frozenset([]) as the missing key. Now
1040 it correctly refers to the initial element.
1041
1042- Fixed C99 style comments in several files. Python is now C89 compatible
1043 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001190- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1191
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001192- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1193 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1194 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1195 ``printf`` function, whereas PyString_FromFormat has an independent
1196 implementation and uses "%zd" on all platforms for size_t values.
1197 This makes a difference on win64, where ``printf`` needs "%Id" to display
1198 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001200- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitrou0668c622008-08-26 22:42:08 +00001218 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1219 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1220 when given a tuple of classes as second argument, were looking up
1221 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1222 type object.

Benjamin Peterson37346b22008-08-23 20:27:43 +00001314Extension Modules
1315-----------------
1316
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001317- Issue #2975: When compiling several extension modules with Visual Studio 2008
1318 from the same python interpreter, some environment variables would grow
1319 without limit.
1320
Benjamin Peterson37346b22008-08-23 20:27:43 +00001321- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1322 exploitation of poor argument checking.
1323
Gerhard Häringef2276b2008-09-12 13:54:06 +00001324- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
1325

1327 remaining ones have "pysqlite_" prefix.
1328
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001329- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1337 wrapper for warnings.catch_warnings() that makes it easier to check
1338 that expected warning messages are being reported.
1339
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001340- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001358What's New in Python 2.6 beta 3?
1359================================
1360
Barry Warsaw07a4a382008-08-21 01:15:08 +00001361*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001362
1363Core and Builtins
1364-----------------
1365
Guido van Rossumf8402962008-08-20 15:01:50 +00001366- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1367 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1368 extensions do not automatically benefit from the class attribute
1369 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1370 to their tp_flags field if they care. This is a backwards
1371 compatibility feature; in 3.0, all types will use the cache by
1372 default.
1373
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001374- Keyword arguments can now follow starred arguments. (``f(a, *args,
1375 keyword=23)`` is now valid syntax.)
1376
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001377- ctypes function pointers that are COM methods have a boolean True
1378 value again.
1379
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001380- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1381 by denying s# to parse objects that have a releasebuffer procedure,
1382 and introducing s*.
1383
Georg Brandl1e13ea92008-08-11 09:07:59 +00001384- Issue #3537: Fix an assertion failure when an empty but presized dict
1385 object was stored in the freelist.
1386
Mark Dickinsonb6467572008-08-04 21:30:09 +00001387- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1388 ValueError consistently across platforms.
1389
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001390- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1391 (64bit Unix, for example), unichr() would truncate its argument and return
1392 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1393
Neal Norwitze7d8be82008-07-31 17:17:14 +00001394- Apply security patches from Apple.
1395
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001396- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1397 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1398
Antoine Pitrou92f82162008-07-25 22:22:08 +00001399- Issue #1819: function calls with several named parameters are now on
1400 average 35% faster (as measured by pybench).
1401
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001402- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1403 the python debugger steps into a class statement: the free variables (local
1404 variables defined in an outer scope) would be deleted from the outer scope.
1405
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001406- Issue #2620: Overflow checking when allocating or reallocating memory
1407 was not always being done properly in some python types and extension
1408 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1409 all been updated to perform better checks and places in the code that
1410 would previously leak memory on the error path when such an allocation
1411 failed have been fixed.
1412
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001413Library
1414-------
1415
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001416- Issue #3612: Added some missing basic types in ctypes.wintypes.
1417
Benjamin Petersone977ad42008-08-20 01:42:01 +00001418- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1419 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1420
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001421- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1422 version reported by these tools does not necessarily follow the python
1423 version numbering scheme, so the module is less strict when parsing it.
1424
Nick Coghlanf70385a2008-08-18 12:42:46 +00001425- Issue #2235: Added Py3k warnings for types which will become unhashable
1426 under the stricter __hash__ inheritance rules in 3.0. Several types
1427 which did not meet the rules for hash invariants and were already
1428 unhashable in 3.0 have now been explicitly flagged as unhashable in
1429 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1430 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1431
Brett Cannon88f801d2008-08-18 00:46:22 +00001432- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1433 imported into the module but exposed as part of the module's API.
1434
Brett Cannon7b96f072008-08-18 00:41:11 +00001435- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1436
Brett Cannon46225e72008-08-18 00:36:52 +00001437- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001439- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1440
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001441- Issue #3575: Incremental decoder's decode function now takes bytearray
1442 by using 's*' instead of 't#'.
1443
Jesus Cea585ad8a2009-07-02 15:37:21 +00001444- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001445 fails unicode conversion on 2nd parameter. (windows only)
1446
Facundo Batista94f243a2008-08-17 03:38:39 +00001447- Issue 2464. urllib2 now supports a malformation in the URL received
1448 in a redirect.
1449
Brett Cannonabe423e2008-08-16 21:47:07 +00001450- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001451 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001452
Facundo Batistaeb90b782008-08-16 14:44:07 +00001453- Issue #2776: fixed small issue when handling an URL with double slash
1454 after a 302 response in the case of not going through a proxy.
1455
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001456- Issue #2676: in the email package, content-type parsing was hanging on
1457 pathological input because of quadratic or exponential behaviour of a
1458 regular expression.
1459
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001460- Issue #3476: binary buffered reading through the new "io" library is now
1461 thread-safe.
1462
Brett Cannonbf3157b2008-08-14 05:00:03 +00001463- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1464 since mimetools itself is deprecated. Because modules are cached, all
1465 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1466
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001467- Issue #3134: shutil referenced undefined WindowsError symbol.
1468
Robert Schuppenies14646332008-08-10 11:01:53 +00001469- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1470 menu entries were not deleted.
1471
Brett Cannon83e81842008-08-09 23:30:55 +00001472- Copied the implementation of reduce() to _functools.reduce() to have a
1473 version that did not raise a DeprecationWarning under -3.
1474
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001475- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1476 a MemoryError rather than silently stop the iteration.
1477
Guido van Rossum59ce9012008-08-09 14:55:34 +00001478- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1479 to _sre.compile() will now be rejected. This should not affect anybody
1480 since the re.compile() function never generates invalid re-bytecode.
1481
Skip Montanaroa032bf42008-08-08 22:52:51 +00001482- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1483 upon first access it can be automatically initialized from the csv file if
1484 it wasn't initialized during instantiation.
1485
Brett Cannon3aa2a492008-08-06 22:28:09 +00001486- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1487 the reload() built-in has been removed.
1488
Brett Cannon7e30b672008-08-04 21:52:25 +00001489- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001490 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1493 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1494 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1495 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

1498 raised an AttributeError.
1499
Benjamin Peterson01a24322008-07-28 23:35:27 +00001500- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001501 asking for a specific length. This problem only affected files opened
1502 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001503
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001504- Issue #3449: Update decimal module to use most recent specification
1505 (v. 1.68) and tests (v. 2.58) from IBM.
1506

1515
1516- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1517 invalid arguments.
1518

1526
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001527- Issue #3394: zipfile.writestr sets external attributes when passed a
1528 file name rather than a ZipInfo instance, so files are extracted with
1529 mode 0600 rather than 000 under Unix.
1530
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001531- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1532 argument in python 2.5, this broke code that subclassed Popen to include its
1533 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001543- Issue #2235: the C API function PyObject_HashNotImplemented and its
1544 interaction with the tp_hash slot (added in 2.6b2) are now documented
1545
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001546- Issue #643841: The language reference now provides more detailed
1547 coverage of the lookup process for special methods. The disclaimers
1548 regarding lack of coverage of new-style classes have also been
1549 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001552What's New in Python 2.6 beta 2?
1553================================
1554
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001555*Release date: 17-Jul-2008*
1556
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001557Core and Builtins
1558-----------------
1559
Georg Brandl3e483f62008-07-16 22:57:41 +00001560- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1561 its methods now allow for items objects that can be converted to
1562 an integer using operator.index().
1563
Mark Dickinson64b7e502008-07-16 09:40:03 +00001564- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1565 produced a ValueError instead of giving the correct float.
1566
Eric Smitha5fa5a22008-07-16 00:11:49 +00001567- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1568 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1569
Mark Dickinson7103aa42008-07-15 19:08:33 +00001570- Issue #3008: the float type has a new instance method 'float.hex'
1571 and a new class method 'float.fromhex' to convert floating-point
1572 numbers to and from hexadecimal strings, respectively.
1573
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001574- Issue #2235: __hash__ is once again inherited by default. To allow
1575 collections.Hashable to remain meaningful in the presence of the
1576 default hash implementation (object.__hash__), it is now possible
1577 to explicit block inheritance of hash by setting __hash__=None at
1578 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1579 level.
1580
Nick Coghlanb028f502008-07-13 14:52:36 +00001581- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1582 the parent module cannot be found while performing an absolute import.
1583 This means that an incorrectly defined __package__ attribute will
1584 now only prevent relative imports in that module rather than causing
1585 all imports from that module to fail.
1586
Nick Coghlan14ff9942008-07-08 14:21:42 +00001587- Issue #2517: Allow unicode messages in Exceptions again by correctly
1588 bypassing the instance dictionary when looking up __unicode__ on
1589 new-style classes.
1590
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001591- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1592 set to a custom object whose write() method happens to install
1593 another file in sys.stdout.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001599- Issue #3004: Minor change to slice.indices(): the start and stop
1600 arguments are now treated identically, making the behaviour easier

1602 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1603 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1604 10, -1).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002120- Issue #1631171: Re-implement the 'warnings' module in C (the
2121 original Python code has been kept as backup). This will allow for
2122 using the 'warning's machinery in such places as the parser where
2123 use of pure Python code is not possible. Both the ``showarning()``
2124 and ``formatwarning()`` gain an optional 'line' argument which is
2125 not called by default for backwards-compatibility reasons. Setting
2126 ``warnings.showwarning()`` to an implementation that lacks support
2127 for the ``line`` argument will raise a DeprecationWarning.

2175 file.close() is called while an object is in use by another thread
2176 an IOError exception will be raised and the file will not be closed.
2177
Thomas Hellerf7906482008-04-04 19:43:25 +00002178- The bundled libffi copy is now in sync with the recently released

2183 so the controlled environment will more closely mirror the typical
2184 script environment. This supports setup.py scripts that refer to
2185 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002190- Issue #2550: The approach used by client/server code for obtaining
2191 ports to listen on in network-oriented tests has been refined in an
2192 effort to facilitate running multiple instances of the entire
2193 regression test suite in parallel without issue.
2194 test_support.bind_port() has been fixed such that it will always
2195 return a unique port -- which wasn't always the case with the
2196 previous implementation, especially if socket options had been set
2197 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2198 new implementation of bind_port() will actually raise an exception
2199 if it is passed an AF_INET/SOCK_STREAM socket with either the
2200 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2201 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2202 the socket it's been passed. This currently only applies to
2203 Windows. This option prevents any other sockets from binding to the
2204 host/port we've bound to, thus removing the possibility of the
2205 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2206 when a second SOCK_STREAM socket binds and accepts to a host/port
2207 that's already been bound by another socket. The optional preferred
2208 port parameter to bind_port() has been removed. Under no
2209 circumstances should tests be hard coding ports!
2210
2211 test_support.find_unused_port() has also been introduced, which will
2212 pass a temporary socket object to bind_port() in order to obtain an
2213 unused port. The temporary socket object is then closed and
2214 deleted, and the port is returned. This method should only be used
2215 for obtaining an unused port in order to pass to an external program
2216 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2217 a parameter to a server-oriented class that doesn't give you direct
2218 access to the underlying socket used.
2219
2220 Finally, test_support.HOST has been introduced, which should be used
2221 for the host argument of any relevant socket calls (i.e. bind and
2222 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002223
2224 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002225 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002226 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2227 test_asynchat and test_socket_ssl.
2228
Georg Brandl3ee81df2008-05-17 18:14:43 +00002229 It is now possible for multiple instances of the regression test
2230 suite to run in parallel without issue.

Facundo Batistac54aec12008-03-08 16:50:27 +00002413- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
Georg Brandl3ee81df2008-05-17 18:14:43 +00002414 optional: it defaults to the traceback of the exception that is
2415 currently being handled (is mandatory to be in the middle of an
2416 exception, otherwise it raises ValueError).
Facundo Batistac54aec12008-03-08 16:50:27 +00002417
Jeffrey Yasskine75f59a2008-03-07 06:22:15 +00002418- Issue #1193577: A .shutdown() method has been added to SocketServers

Georg Brandl3ee81df2008-05-17 18:14:43 +00002424- Issue #2225: py_compile, when executed as a script, now returns a
2425 non- zero status code if not all files could be compiled
2426 successfully.
Georg Brandla7bd27f2008-03-06 07:41:16 +00002427
Georg Brandl3ee81df2008-05-17 18:14:43 +00002428- Bug #1725737: In distutils' sdist, exclude RCS, CVS etc. also in the

Thomas Hellerf3c05592008-03-05 15:34:29 +00002431- Issue #1872: The struct module typecode for _Bool has been changed
2432 from 't' to '?'.
2433
Thomas Heller78b8f442008-03-05 14:53:39 +00002434- The bundled libffi copy is now in sync with the recently released
2435 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002436 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2437 files are used. On all linux systems the --with-system-ffi
2438 configure option defaults to "yes".

2497-----------------
2498
Fred Drakea8ee94b2008-03-01 02:45:07 +00002499- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002500 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002501
Georg Brandlad61bc82008-02-23 15:11:18 +00002502- Issue #2067: file.__exit__() now calls subclasses' close() method.
2503
2504- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002505
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002506- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002507 issue 215555 for a discussion.
2508
Eric Smitha73fbe72008-02-23 03:09:44 +00002509- Added the future_builtins module, which contains hex() and oct().
2510 These are the PEP 3127 version of these functions, designed to be
2511 compatible with the hex() and oct() builtins from Python 3.0. They
2512 differ slightly in their output formats from the existing, unchanged
2513 Python 2.6 builtins. The expected usage of the future_builtins
2514 module is:
2515 from future_builtins import hex, oct
2516
Eric Smith7ef40bf2008-02-20 23:34:22 +00002517- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2518 exponents for exponents with absolute value < 100. Follows C99
2519 standard. This is a change on Windows, which would use 3 digits.
2520 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2521 so that any alterations it does to the resulting string will be
2522 available in stringlib/formatter.h (for float.__format__).
2523
Eric Smith5a3c1352008-02-19 13:21:56 +00002524- Implemented PEP 3101, Advanced String Formatting. This adds a new
2525 builtin format(); a format() method for str and unicode; a
2526 __format__() method to object, str, unicode, int, long, float, and
2527 datetime; the class string.Formatter; and the C API
2528 PyObject_Format().
2529
Georg Brandl3ee81df2008-05-17 18:14:43 +00002530- Fixed several potential crashes, all caused by specially crafted
2531 __del__ methods exploiting objects in temporarily inconsistent
2532 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002533
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002534- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002535 prevent a possible crash: an Abstract Base Class would try to access
2536 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002537
Georg Brandl3ee81df2008-05-17 18:14:43 +00002538- Fixed repr() and str() of complex numbers with infinity or nan as
2539 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002540
Georg Brandl3ee81df2008-05-17 18:14:43 +00002541- Clear all free lists during a gc.collect() of the highest generation
2542 in order to allow pymalloc to free more arenas. Python may give back
2543 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002544
Georg Brandl3ee81df2008-05-17 18:14:43 +00002545- Issue #2045: Fix an infinite recursion triggered when printing a
2546 subclass of collections.defaultdict, if its default_factory is set
2547 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002548
Christian Heimesf75dbef2008-02-08 00:11:31 +00002549- Fixed a minor memory leak in dictobject.c. The content of the free
2550 list was not freed on interpreter shutdown.
2551
Georg Brandl3ee81df2008-05-17 18:14:43 +00002552- Limit free list of method and builtin function objects to 256
2553 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002554
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2556 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002557 to compact the internal free lists of pre-allocted ints and floats.
2558
Georg Brandl3ee81df2008-05-17 18:14:43 +00002559- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2560 calls. Python expected the return type int but the fork familie
2561 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002562
Georg Brandl3ee81df2008-05-17 18:14:43 +00002563- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2564 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002565
Georg Brandl3ee81df2008-05-17 18:14:43 +00002566- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2567 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002568
Georg Brandl3ee81df2008-05-17 18:14:43 +00002569- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2570 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002572- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2573 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002574
Georg Brandl3ee81df2008-05-17 18:14:43 +00002575- Patch #1473257: generator objects gain a gi_code attribute. This is
2576 the same object as the func_code attribute of the function that
2577 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002578
Georg Brandl3ee81df2008-05-17 18:14:43 +00002579- Issue #1920: "while 0" statements were completely removed by the
2580 compiler, even in the presence of an "else" clause, which is
2581 supposed to be run when the condition is false. Now the compiler
2582 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002583
Guido van Rossumeead05f2008-01-24 18:21:02 +00002584- A few crashers fixed: weakref_in_del.py (issue #1377858);
2585 loosing_dict_ref.py (issue #1303614, test67.py);
2586 borrowed_ref_[34].py (not in tracker).
2587
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002588- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002589 suppressed while an extension is loaded by calling SetErrorMode in
2590 dynload_win.c. The error is still reported properly.
2591
Georg Brandl3ee81df2008-05-17 18:14:43 +00002592- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002593 several extension methods and modules do not work without unicode
2594 support.
2595
Georg Brandl26543b12008-01-21 18:36:51 +00002596- Issue #1882: when compiling code from a string, encoding cookies in the
2597 second line of code were not always recognized correctly.
2598
Georg Brandl14404b62008-01-19 19:27:05 +00002599- Issue #1679: "0x" was taken as a valid integer literal.
2600
Georg Brandl6caad7d2008-01-26 14:19:22 +00002601- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002602 added.
2603
Christian Heimesc94e2b52008-01-14 04:13:37 +00002604- sys.float_info / PyFloat_GetInfo: The floating point information
2605 object was converted from a dict to a specialized structseq object.
2606
Georg Brandl3ee81df2008-05-17 18:14:43 +00002607- Patch #1816: Added sys.flags structseq. It exposes the status of
2608 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002609
Georg Brandl3ee81df2008-05-17 18:14:43 +00002610- Objects/structseq.c: Implemented new structseq representation. The
2611 patch makes structseqs (e.g. the return value of os.stat) more
2612 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002613
Georg Brandl3ee81df2008-05-17 18:14:43 +00002614- Patch #1700288: added a type attribute cache that caches method
2615 accesses, resulting in speedups in heavily object-oriented code.

2623 envvar and sys.dont_write_bytecode attribute. All these can be set
2624 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002625
Georg Brandl3ee81df2008-05-17 18:14:43 +00002626- Improve some exception messages when Windows fails to load an
2627 extension module. Now we get for example '%1 is not a valid Win32
2628 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002629

Christian Heimes0a8143f2007-12-18 23:22:54 +00002635- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002636 and INF. float("nan"), float("inf") and float("-inf") now work on
2637 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002638
Georg Brandl3ee81df2008-05-17 18:14:43 +00002639- Compiler now generates simpler and faster code for dictionary
2640 literals. The oparg for BUILD_MAP now indicates an estimated
2641 dictionary size. There is a new opcode, STORE_MAP, for adding
2642 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002671- Patch #1739468: Directories and zipfiles containing a __main__.py
2672 file can now be directly executed by passing their name to the
2673 interpreter. The directory/zipfile is automatically inserted as the
2674 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002676- Issue #1265: Fix a problem with sys.settrace, if the tracing
2677 function uses a generator expression when at the same time the
2678 executed code is closing a paused generator.

2685
Georg Brandl3ee81df2008-05-17 18:14:43 +00002686- The enumerate() builtin function is no longer bounded to sequences
2687 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2688 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002689
Georg Brandl3ee81df2008-05-17 18:14:43 +00002690- Issue #1686386: Tuple's tp_repr did not take into account the
2691 possibility of having a self-referential tuple, which is possible
2692 from C code. Nor did object's tp_str consider that a type's tp_str
2693 could do something that could lead to an inifinite recursion.
2694 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2695 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002696
Georg Brandl3ee81df2008-05-17 18:14:43 +00002697- Issue #1164: It was possible to trigger deadlock when using the
2698 'print' statement to write to a file since the GIL was not released
2699 as needed. Now PyObject_Print() does the right thing along with
2700 various tp_print implementations of the built-in types and those in
2701 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002702
Georg Brandl3ee81df2008-05-17 18:14:43 +00002703- Issue #1147: Exceptions were directly allowing string exceptions in

2705 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00002710- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002711 PyObject_Call() never calling back out to Python code to trigger
2712 recursion depth updates/checks. Required the creation of a static
2713 RuntimeError instance in case normalizing an exception put the
2714 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00002730- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002731 __*__ attributes. (Some already existed, e.g., __doc__ and
2732 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002733
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002734- Add -3 option to the interpreter to warn about features that are

2736
Georg Brandl2134e752007-05-21 20:34:16 +00002737- Patch #1686487: you can now pass any mapping after '**' in function
2738 calls.
2739
Collin Winter62903052007-05-18 23:11:24 +00002740- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002741 "except E as target:". This is to provide forwards compatibility
2742 with Python 3.0.

2748
Vinay Sajip8549ce32007-05-06 17:53:37 +00002749- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002750 setting a plain string, ie don't expand to single letter identifiers.
2751
Raymond Hettinger13936692007-04-11 18:40:58 +00002752- Request #1191699: Slices can now be pickled.
2753
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002754- Request #1193128: str.translate() now allows a None argument for

2756 remaining characters.
2757
Georg Brandl5cb76c12007-03-21 09:00:39 +00002758- Patch #1682205: a TypeError while unpacking an iterable is no longer

2762
Guido van Rossum143b5642007-03-23 04:58:42 +00002763- Bug #1683368: The object.__init__() and object.__new__() methods are
2764 now stricter in rejecting excess arguments. The only time when
2765 either allows excess arguments is when it is not overridden and the
2766 other one is. For backwards compatibility, when both are
2767 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002768 warning later). Also, type.__init__() insists on the same signature
2769 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002770
Georg Brandl3ee81df2008-05-17 18:14:43 +00002771- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2772 object to complex using its __complex__() method before falling back
2773 to the __float__() method. Therefore, the functions in the cmath
2774 module now can operate on objects that define a __complex__()
2775 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002776
Georg Brandl3ee81df2008-05-17 18:14:43 +00002777- Patch #1623563: allow __class__ assignment for classes with
2778 __slots__. The old and the new class are still required to have the
2779 same slot names.

2786 its type.

2792
Georg Brandl7b9c5552007-03-12 14:30:05 +00002793- Bug #1678647: write a newline after printing an exception in any
2794 case, even when converting the value to a string failed.
2795
Georg Brandl871f1bc2007-03-12 13:17:36 +00002796- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002797 its argument, if it exists. If not, it will work like before. This
2798 allows customizing the output of dir() in the presence of a
2799 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002807- Patch #1491866: change the complex() constructor to allow
2808 parthensized forms. This means complex(repr(x)) now works instead of
2809 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002810
Georg Brandlaa2321b2007-03-07 00:40:28 +00002811- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002812 makes the filenames the warning module prints much more sensible
2813 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002826- Patch #1674228: when assigning a slice (old-style), check for the
2827 sq_ass_slice instead of the sq_slice slot.
2828
Georg Brandl3ee81df2008-05-17 18:14:43 +00002829- When printing an unraisable error, don't print exceptions. before
2830 the name. This duplicates the behavior whening normally printing
2831 exceptions.

2888
Armin Rigo7ccbca92006-10-04 12:17:45 +00002889- A number of places, including integer negation and absolute value,

Georg Brandl3ee81df2008-05-17 18:14:43 +00003399 are set for invalid interpolation sequences that would lead to

3456 TestCase and TestSuite subclasses (not instances) are no longer
3457 accepted in TestSuite.addTest(). This should cause no
3458 incompatibility since it never made sense with ordinary subclasses
3459 -- the failure just occurred later, with a more cumbersome
3460 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003741- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3742 with RFC 3207 and forgets any knowledge obtained from the server not
3743 obtained from the TLS negotiation itself. Patch contributed by Bill
3744 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003745
Georg Brandl3ee81df2008-05-17 18:14:43 +00003746- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003747 that the SMTP.starttls() caller no longer needs to call ehlo()
3748 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003749 does not claim to support starttls. Adds the
3750 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00003805- itertools.chain() now has an alternate constructor,

3831 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3832 silently miscode subclasses of those types. Now, it raises a
3833 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003834

Georg Brandl3ee81df2008-05-17 18:14:43 +00003849 time so that opening a database previously created with the DB_DUP
3850 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3851 opens. Specifically: dictionary assignment to a DB object will
3852 replace all values for a given key when the database allows
3853 duplicate values. DB users should use DB.put(k, v) when they want
3854 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003855

3861 characters with ASCII value less than 32. Also, it correctly quotes
3862 dots only if they occur on a single line, as opposed to the previous
3863 behavior of quoting dots if they are the second character of any
3864 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003865

4129 without this option!
4130
Martin v. Löwis63bf1492007-11-12 05:14:05 +00004131- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
4132
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004133- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004134 periodic threadstate and signal checking in tight loops. By
4135 default, this option is turned-off. It should only be enabled in
4136 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004137

4152 returned by python-config if Python was built with --enable-shared
4153 because that prevented the shared library from being used.

4187-----
4188
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189- Unified naming convention for free lists and their limits. All free
4190 lists in Object/ are named ``free_list``, the counter ``numfree``
4191 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4192 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004193
Georg Brandl3ee81df2008-05-17 18:14:43 +00004194- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4195 to ``PyTuple_SetItem``, it can be used to populate a brand new
4196 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004197
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004198- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

4205
4206- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4207 ``PyFloat_GetInfo()`` to the float API.
4208
Georg Brandl3ee81df2008-05-17 18:14:43 +00004209- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4210 of w# format code incorrectly truncated the length to an int, even
4211 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4212 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004213
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4232- Fix some leftovers from the conversion from int to Py_ssize_t
4233 (relevant to strings and sequences of more than 2**31 items).
4234
4235- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4236 outside of pystate.c and should not be necessary.
4237
Georg Brandl3ee81df2008-05-17 18:14:43 +00004238- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4239 absolute imports. In earlier versions they might have used relative
4240 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004241
Georg Brandl3ee81df2008-05-17 18:14:43 +00004242- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4243 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004244
Georg Brandl3ee81df2008-05-17 18:14:43 +00004245- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4253 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4254 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4255 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004256

Georg Brandl3ee81df2008-05-17 18:14:43 +00004270- Removed the macfs module. It had been deprecated since Python 2.5.
4271 This lead to the deprecation of macostools.touched() as it relied
4272 solely on macfs and was a no-op under OS X.
