723 do an explicit seek to the end of file (so that e.g. tell() returns the
724 file size rather than 0). This is consistent with the behaviour of the
725 traditional 2.x file object.

921What's New in Python 2.6.1
922==========================
923
924*Release date: 04-Dec-2008*
925
926Core and Builtins
927-----------------
928
929- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
930 interpreter to abort ("Fatal Python error: Could not reset the stack!")
931 instead of throwing a MemoryError.
932
933- Issue #4367: Python would segfault during compiling when the unicodedata
934 module couldn't be imported and \N escapes were present.
935
936- Issue #4348: Some bytearray methods returned that didn't cause any change to
937 the bytearray, returned the same bytearray instead of a copy.
938
939- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
940
941- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
942
943- Issue #4048: The parser module now correctly validates relative imports.
944
945- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
946 exec statement.
947
948- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
949 method does not return iterators for the 4th and 5th items.
950
951- Issue #4209: Enabling unicode_literals and the print_function in the same
952 __future__ import didn't work.
953
954- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
955 returned a path longer than MAX_PATH. (But It's doubtful this code path is
956 really executed because I cannot move to such directory on win2k)
957
958- Issue #4069: When set.remove(element) is used with a set element, the element
959 is temporarily replaced with an equivalent frozenset. But the eventual
960 KeyError would always report the empty frozenset([]) as the missing key. Now
961 it correctly refers to the initial element.
962
963- Fixed C99 style comments in several files. Python is now C89 compatible
964 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001111- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1112
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001113- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1114 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1115 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1116 ``printf`` function, whereas PyString_FromFormat has an independent
1117 implementation and uses "%zd" on all platforms for size_t values.
1118 This makes a difference on win64, where ``printf`` needs "%Id" to display
1119 64bit values.

1125 object; previously an int would be returned for small values. the __long__
1126 method is allowed to return either an int or a long, but the behaviour of
1127 float objects should not change to respect backward compatibility.
1128
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001129- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001135 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001136 was correctly parsed but parsing of subsequent arguments failed.
1137
Vinay Sajip35e3b032008-09-01 14:33:59 +00001138- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001139 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1140 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1141 when given a tuple of classes as second argument, were looking up
1142 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1143 type object.
1144
Neal Norwitz18aa3882008-08-24 05:04:52 +00001145- Fix crashes on memory allocation failure found with failmalloc.

1285-----------------
1286
Guido van Rossumf8402962008-08-20 15:01:50 +00001287- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1288 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1289 extensions do not automatically benefit from the class attribute
1290 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1291 to their tp_flags field if they care. This is a backwards
1292 compatibility feature; in 3.0, all types will use the cache by
1293 default.
1294
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001295- Keyword arguments can now follow starred arguments. (``f(a, *args,

1306 object was stored in the freelist.
1307
Mark Dickinsonb6467572008-08-04 21:30:09 +00001308- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1309 ValueError consistently across platforms.
1310
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001311- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1312 (64bit Unix, for example), unichr() would truncate its argument and return
1313 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1314
Neal Norwitze7d8be82008-07-31 17:17:14 +00001315- Apply security patches from Apple.
1316
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001317- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1318 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1319
Antoine Pitrou92f82162008-07-25 22:22:08 +00001320- Issue #1819: function calls with several named parameters are now on
1321 average 35% faster (as measured by pybench).
1322
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001323- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1324 the python debugger steps into a class statement: the free variables (local
1325 variables defined in an outer scope) would be deleted from the outer scope.
1326
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001327- Issue #2620: Overflow checking when allocating or reallocating memory
1328 was not always being done properly in some python types and extension
1329 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1330 all been updated to perform better checks and places in the code that
1331 would previously leak memory on the error path when such an allocation
1332 failed have been fixed.

1338
Benjamin Petersone977ad42008-08-20 01:42:01 +00001339- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1340 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1341
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001342- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1343 version reported by these tools does not necessarily follow the python
1344 version numbering scheme, so the module is less strict when parsing it.
1345
Nick Coghlanf70385a2008-08-18 12:42:46 +00001346- Issue #2235: Added Py3k warnings for types which will become unhashable
1347 under the stricter __hash__ inheritance rules in 3.0. Several types
1348 which did not meet the rules for hash invariants and were already
1349 unhashable in 3.0 have now been explicitly flagged as unhashable in
1350 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1351 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1352
Brett Cannon88f801d2008-08-18 00:46:22 +00001353- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1354 imported into the module but exposed as part of the module's API.
1355
Brett Cannon7b96f072008-08-18 00:41:11 +00001356- Remove an unneeded import of abc.ABCMeta from 'inspect'.

1361
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001362- Issue #3575: Incremental decoder's decode function now takes bytearray
1363 by using 's*' instead of 't#'.
1364
Jesus Cea585ad8a2009-07-02 15:37:21 +00001365- Issue #2222: Fixed reference leak when occurred os.rename()

1375 after a 302 response in the case of not going through a proxy.
1376
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001377- Issue #2676: in the email package, content-type parsing was hanging on
1378 pathological input because of quadratic or exponential behaviour of a
1379 regular expression.
1380
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001381- Issue #3476: binary buffered reading through the new "io" library is now
1382 thread-safe.
1383
Brett Cannonbf3157b2008-08-14 05:00:03 +00001384- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1385 since mimetools itself is deprecated. Because modules are cached, all
1386 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1387
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001388- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001390- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1391 menu entries were not deleted.
1392
Brett Cannon83e81842008-08-09 23:30:55 +00001393- Copied the implementation of reduce() to _functools.reduce() to have a
1394 version that did not raise a DeprecationWarning under -3.
1395
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001396- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1397 a MemoryError rather than silently stop the iteration.
1398
Guido van Rossum59ce9012008-08-09 14:55:34 +00001399- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1400 to _sre.compile() will now be rejected. This should not affect anybody
1401 since the re.compile() function never generates invalid re-bytecode.
1402
Skip Montanaroa032bf42008-08-08 22:52:51 +00001403- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1404 upon first access it can be automatically initialized from the csv file if
1405 it wasn't initialized during instantiation.
1406
Brett Cannon3aa2a492008-08-06 22:28:09 +00001407- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1408 the reload() built-in has been removed.
1409
Brett Cannon7e30b672008-08-04 21:52:25 +00001410- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001411 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1419 raised an AttributeError.
1420
Benjamin Peterson01a24322008-07-28 23:35:27 +00001421- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001422 asking for a specific length. This problem only affected files opened
1423 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001424
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001425- Issue #3449: Update decimal module to use most recent specification
1426 (v. 1.68) and tests (v. 2.58) from IBM.

1447
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001448- Issue #3394: zipfile.writestr sets external attributes when passed a
1449 file name rather than a ZipInfo instance, so files are extracted with
1450 mode 0600 rather than 000 under Unix.
1451
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001452- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1453 argument in python 2.5, this broke code that subclassed Popen to include its
1454 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1463
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001464- Issue #2235: the C API function PyObject_HashNotImplemented and its
1465 interaction with the tp_hash slot (added in 2.6b2) are now documented
1466
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001467- Issue #643841: The language reference now provides more detailed
1468 coverage of the lookup process for special methods. The disclaimers
1469 regarding lack of coverage of new-style classes have also been
1470 removed, since the coverage is now fairly reasonable.

1474================================
1475
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001476*Release date: 17-Jul-2008*
1477
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001478Core and Builtins
1479-----------------
1480
Georg Brandl3e483f62008-07-16 22:57:41 +00001481- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1482 its methods now allow for items objects that can be converted to
1483 an integer using operator.index().
1484
Mark Dickinson64b7e502008-07-16 09:40:03 +00001485- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1486 produced a ValueError instead of giving the correct float.
1487
Eric Smitha5fa5a22008-07-16 00:11:49 +00001488- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1489 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1490
Mark Dickinson7103aa42008-07-15 19:08:33 +00001491- Issue #3008: the float type has a new instance method 'float.hex'
1492 and a new class method 'float.fromhex' to convert floating-point
1493 numbers to and from hexadecimal strings, respectively.
1494
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001495- Issue #2235: __hash__ is once again inherited by default. To allow
1496 collections.Hashable to remain meaningful in the presence of the
1497 default hash implementation (object.__hash__), it is now possible
1498 to explicit block inheritance of hash by setting __hash__=None at
1499 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1500 level.
1501
Nick Coghlanb028f502008-07-13 14:52:36 +00001502- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1503 the parent module cannot be found while performing an absolute import.
1504 This means that an incorrectly defined __package__ attribute will
1505 now only prevent relative imports in that module rather than causing
1506 all imports from that module to fail.
1507
Nick Coghlan14ff9942008-07-08 14:21:42 +00001508- Issue #2517: Allow unicode messages in Exceptions again by correctly
1509 bypassing the instance dictionary when looking up __unicode__ on
1510 new-style classes.
1511
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001512- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1513 set to a custom object whose write() method happens to install
1514 another file in sys.stdout.
1515
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001516- Issue #3088: Corrected a race condition in classes derived from
1517 threading.local: the first member set by a thread could be saved in
1518 another thread's dictionary.
1519
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001520- Issue #3004: Minor change to slice.indices(): the start and stop
1521 arguments are now treated identically, making the behaviour easier
1522 to describe and understand. For example, slice(None, -10,
1523 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1524 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1525 10, -1).
1526
Georg Brandl278fc502008-07-19 12:46:12 +00001527- Issue #3219: Calling a function with repeated keyword arguments,
1528 f(a=2, a=23), would not cause a syntax error. This was a regression
1529 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001530
Georg Brandl278fc502008-07-19 12:46:12 +00001531- Issue #2862: Make int and float freelist management consistent with
1532 other freelists. Changes their CompactFreeList apis into
1533 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001534

1536-------
1537
Thomas Heller57adf222008-08-14 19:10:48 +00001538- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1539 api functions without holding the GIL, which could lead to a fatal
1540 error when they failed.
1541
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001542- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001550- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1551 ForkingPickler.register() to resolve conflict with ctypes.
1552
Vinay Sajip51e65192008-07-18 09:01:10 +00001553- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001554
Thomas Heller880f5292008-07-15 19:39:38 +00001555- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1556 a valid dlerror() message.
1557
Thomas Heller2bad6572008-07-15 17:19:50 +00001558- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1559 incomplete structure was created.
1560
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001561- Issue #3339: dummy_thread.acquire() should not return None.
1562
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001563- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1564
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001565- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001566
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001567- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1568 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001569 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001570 content-length. The problem had been corrected in the 2.4 branch, but never
1571 merged into trunk.
1572
Georg Brandle78fbcc2008-07-05 10:13:36 +00001573- Issue #2663: add filtering capability to shutil.copytree().

1577- Issue #1526: Allow more than 64k files to be added to Zip64 file.
1578
1579- Issue #1746: Correct handling of zipfile archive comments (previously
1580 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001581 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001582
Vinay Sajip51e65192008-07-18 09:01:10 +00001583- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001584 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001585
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001586- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00001979 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001980
1981 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00002041- Issue #1631171: Re-implement the 'warnings' module in C (the
2042 original Python code has been kept as backup). This will allow for
2043 using the 'warning's machinery in such places as the parser where
2044 use of pure Python code is not possible. Both the ``showarning()``
2045 and ``formatwarning()`` gain an optional 'line' argument which is
2046 not called by default for backwards-compatibility reasons. Setting
2047 ``warnings.showwarning()`` to an implementation that lacks support
2048 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Issue #2550: The approach used by client/server code for obtaining
2112 ports to listen on in network-oriented tests has been refined in an
2113 effort to facilitate running multiple instances of the entire
2114 regression test suite in parallel without issue.
2115 test_support.bind_port() has been fixed such that it will always
2116 return a unique port -- which wasn't always the case with the
2117 previous implementation, especially if socket options had been set
2118 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2119 new implementation of bind_port() will actually raise an exception
2120 if it is passed an AF_INET/SOCK_STREAM socket with either the
2121 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2122 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2123 the socket it's been passed. This currently only applies to
2124 Windows. This option prevents any other sockets from binding to the
2125 host/port we've bound to, thus removing the possibility of the
2126 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2127 when a second SOCK_STREAM socket binds and accepts to a host/port
2128 that's already been bound by another socket. The optional preferred
2129 port parameter to bind_port() has been removed. Under no
2130 circumstances should tests be hard coding ports!
2131
2132 test_support.find_unused_port() has also been introduced, which will
2133 pass a temporary socket object to bind_port() in order to obtain an
2134 unused port. The temporary socket object is then closed and
2135 deleted, and the port is returned. This method should only be used
2136 for obtaining an unused port in order to pass to an external program
2137 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2138 a parameter to a server-oriented class that doesn't give you direct
2139 access to the underlying socket used.
2140
2141 Finally, test_support.HOST has been introduced, which should be used
2142 for the host argument of any relevant socket calls (i.e. bind and
2143 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002144
2145 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002146 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002147 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2148 test_asynchat and test_socket_ssl.
2149
Georg Brandl3ee81df2008-05-17 18:14:43 +00002150 It is now possible for multiple instances of the regression test
2151 suite to run in parallel without issue.

2417Core and builtins
2418-----------------
2419
Fred Drakea8ee94b2008-03-01 02:45:07 +00002420- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002421 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002422
Georg Brandlad61bc82008-02-23 15:11:18 +00002423- Issue #2067: file.__exit__() now calls subclasses' close() method.
2424
2425- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002426
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002427- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002428 issue 215555 for a discussion.
2429
Eric Smitha73fbe72008-02-23 03:09:44 +00002430- Added the future_builtins module, which contains hex() and oct().
2431 These are the PEP 3127 version of these functions, designed to be
2432 compatible with the hex() and oct() builtins from Python 3.0. They
2433 differ slightly in their output formats from the existing, unchanged
2434 Python 2.6 builtins. The expected usage of the future_builtins
2435 module is:
2436 from future_builtins import hex, oct
2437
Eric Smith7ef40bf2008-02-20 23:34:22 +00002438- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2439 exponents for exponents with absolute value < 100. Follows C99
2440 standard. This is a change on Windows, which would use 3 digits.
2441 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2442 so that any alterations it does to the resulting string will be
2443 available in stringlib/formatter.h (for float.__format__).
2444
Eric Smith5a3c1352008-02-19 13:21:56 +00002445- Implemented PEP 3101, Advanced String Formatting. This adds a new
2446 builtin format(); a format() method for str and unicode; a
2447 __format__() method to object, str, unicode, int, long, float, and
2448 datetime; the class string.Formatter; and the C API
2449 PyObject_Format().
2450
Georg Brandl3ee81df2008-05-17 18:14:43 +00002451- Fixed several potential crashes, all caused by specially crafted
2452 __del__ methods exploiting objects in temporarily inconsistent
2453 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002454
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002455- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002456 prevent a possible crash: an Abstract Base Class would try to access
2457 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002458
Georg Brandl3ee81df2008-05-17 18:14:43 +00002459- Fixed repr() and str() of complex numbers with infinity or nan as
2460 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002461
Georg Brandl3ee81df2008-05-17 18:14:43 +00002462- Clear all free lists during a gc.collect() of the highest generation
2463 in order to allow pymalloc to free more arenas. Python may give back
2464 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002465
Georg Brandl3ee81df2008-05-17 18:14:43 +00002466- Issue #2045: Fix an infinite recursion triggered when printing a
2467 subclass of collections.defaultdict, if its default_factory is set
2468 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002469
Christian Heimesf75dbef2008-02-08 00:11:31 +00002470- Fixed a minor memory leak in dictobject.c. The content of the free
2471 list was not freed on interpreter shutdown.
2472
Georg Brandl3ee81df2008-05-17 18:14:43 +00002473- Limit free list of method and builtin function objects to 256
2474 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002475
Georg Brandl3ee81df2008-05-17 18:14:43 +00002476- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2477 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002478 to compact the internal free lists of pre-allocted ints and floats.
2479
Georg Brandl3ee81df2008-05-17 18:14:43 +00002480- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2481 calls. Python expected the return type int but the fork familie
2482 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002483
Georg Brandl3ee81df2008-05-17 18:14:43 +00002484- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2485 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002486
Georg Brandl3ee81df2008-05-17 18:14:43 +00002487- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2488 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002489
Georg Brandl3ee81df2008-05-17 18:14:43 +00002490- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2491 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002492
Georg Brandl3ee81df2008-05-17 18:14:43 +00002493- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2494 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002495
Georg Brandl3ee81df2008-05-17 18:14:43 +00002496- Patch #1473257: generator objects gain a gi_code attribute. This is
2497 the same object as the func_code attribute of the function that
2498 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002499
Georg Brandl3ee81df2008-05-17 18:14:43 +00002500- Issue #1920: "while 0" statements were completely removed by the
2501 compiler, even in the presence of an "else" clause, which is
2502 supposed to be run when the condition is false. Now the compiler
2503 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002504
Guido van Rossumeead05f2008-01-24 18:21:02 +00002505- A few crashers fixed: weakref_in_del.py (issue #1377858);
2506 loosing_dict_ref.py (issue #1303614, test67.py);
2507 borrowed_ref_[34].py (not in tracker).
2508
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002509- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002510 suppressed while an extension is loaded by calling SetErrorMode in
2511 dynload_win.c. The error is still reported properly.
2512
Georg Brandl3ee81df2008-05-17 18:14:43 +00002513- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002514 several extension methods and modules do not work without unicode
2515 support.
2516
Georg Brandl26543b12008-01-21 18:36:51 +00002517- Issue #1882: when compiling code from a string, encoding cookies in the
2518 second line of code were not always recognized correctly.
2519
Georg Brandl14404b62008-01-19 19:27:05 +00002520- Issue #1679: "0x" was taken as a valid integer literal.
2521
Georg Brandl6caad7d2008-01-26 14:19:22 +00002522- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002523 added.
2524
Christian Heimesc94e2b52008-01-14 04:13:37 +00002525- sys.float_info / PyFloat_GetInfo: The floating point information
2526 object was converted from a dict to a specialized structseq object.
2527
Georg Brandl3ee81df2008-05-17 18:14:43 +00002528- Patch #1816: Added sys.flags structseq. It exposes the status of
2529 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002530
Georg Brandl3ee81df2008-05-17 18:14:43 +00002531- Objects/structseq.c: Implemented new structseq representation. The
2532 patch makes structseqs (e.g. the return value of os.stat) more
2533 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002534
Georg Brandl3ee81df2008-05-17 18:14:43 +00002535- Patch #1700288: added a type attribute cache that caches method
2536 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002537
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002538- Bug #1776: __import__() no longer accepts filenames on any platform.
2539 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002540
Georg Brandlaed6c662008-01-07 17:25:53 +00002541- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2542
Georg Brandl3ee81df2008-05-17 18:14:43 +00002543- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2544 envvar and sys.dont_write_bytecode attribute. All these can be set
2545 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002546
Georg Brandl3ee81df2008-05-17 18:14:43 +00002547- Improve some exception messages when Windows fails to load an
2548 extension module. Now we get for example '%1 is not a valid Win32
2549 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002550
Georg Brandl3ee81df2008-05-17 18:14:43 +00002551- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002553- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2554 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002555
Christian Heimes0a8143f2007-12-18 23:22:54 +00002556- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002557 and INF. float("nan"), float("inf") and float("-inf") now work on
2558 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002559
Georg Brandl3ee81df2008-05-17 18:14:43 +00002560- Compiler now generates simpler and faster code for dictionary
2561 literals. The oparg for BUILD_MAP now indicates an estimated
2562 dictionary size. There is a new opcode, STORE_MAP, for adding
2563 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002564
Georg Brandl3ee81df2008-05-17 18:14:43 +00002565- Issue #1638: %zd configure test fails on Linux.

2581 running, and if the deallocation of its frames somehow calls the
2582 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002583

2593 file can now be directly executed by passing their name to the
2594 interpreter. The directory/zipfile is automatically inserted as the
2595 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002596
Georg Brandl3ee81df2008-05-17 18:14:43 +00002597- Issue #1265: Fix a problem with sys.settrace, if the tracing
2598 function uses a generator expression when at the same time the
2599 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002600
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002601- sets and frozensets now have an isdisjoint() method.
2602
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002603- optimize the performance of builtin.sum().
2604
Neal Norwitz44f326e2007-10-05 05:29:17 +00002605- Fix warnings found by the new version of the Coverity checker.
2606
Georg Brandl3ee81df2008-05-17 18:14:43 +00002607- The enumerate() builtin function is no longer bounded to sequences
2608 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2609 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002610
Georg Brandl3ee81df2008-05-17 18:14:43 +00002611- Issue #1686386: Tuple's tp_repr did not take into account the
2612 possibility of having a self-referential tuple, which is possible
2613 from C code. Nor did object's tp_str consider that a type's tp_str
2614 could do something that could lead to an inifinite recursion.
2615 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2616 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002617
Georg Brandl3ee81df2008-05-17 18:14:43 +00002618- Issue #1164: It was possible to trigger deadlock when using the
2619 'print' statement to write to a file since the GIL was not released
2620 as needed. Now PyObject_Print() does the right thing along with
2621 various tp_print implementations of the built-in types and those in
2622 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002624- Issue #1147: Exceptions were directly allowing string exceptions in
2625 their throw() method even though string exceptions no longer
2626 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002627
Georg Brandl3ee81df2008-05-17 18:14:43 +00002628- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002631- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002632 PyObject_Call() never calling back out to Python code to trigger
2633 recursion depth updates/checks. Required the creation of a static
2634 RuntimeError instance in case normalizing an exception put the
2635 recursion check value past its limit. Fixes crashers
2636 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002651- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002652 __*__ attributes. (Some already existed, e.g., __doc__ and
2653 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002654
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002655- Add -3 option to the interpreter to warn about features that are
2656 deprecated and will be changed/removed in Python 3.0.
2657

2659 calls.
2660
Collin Winter62903052007-05-18 23:11:24 +00002661- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002662 "except E as target:". This is to provide forwards compatibility
2663 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002664
Brett Cannon229cee22007-05-05 01:34:02 +00002665- Deprecate BaseException.message as per PEP 352.
2666
Georg Brandl3ee81df2008-05-17 18:14:43 +00002667- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002668 inherited from a builtin base.
2669
Vinay Sajip8549ce32007-05-06 17:53:37 +00002670- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002671 setting a plain string, ie don't expand to single letter identifiers.
2672
Raymond Hettinger13936692007-04-11 18:40:58 +00002673- Request #1191699: Slices can now be pickled.
2674
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002675- Request #1193128: str.translate() now allows a None argument for
2676 translations that only remove characters without re-mapping the
2677 remaining characters.
2678
Georg Brandl5cb76c12007-03-21 09:00:39 +00002679- Patch #1682205: a TypeError while unpacking an iterable is no longer
2680 masked by a generic one with the message "unpack non-sequence".
2681
Neal Norwitzaa754b72007-03-21 06:39:48 +00002682- Remove unused file Python/fmod.c.
2683
Guido van Rossum143b5642007-03-23 04:58:42 +00002684- Bug #1683368: The object.__init__() and object.__new__() methods are
2685 now stricter in rejecting excess arguments. The only time when
2686 either allows excess arguments is when it is not overridden and the
2687 other one is. For backwards compatibility, when both are
2688 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002689 warning later). Also, type.__init__() insists on the same signature
2690 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002691
Georg Brandl3ee81df2008-05-17 18:14:43 +00002692- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2693 object to complex using its __complex__() method before falling back
2694 to the __float__() method. Therefore, the functions in the cmath
2695 module now can operate on objects that define a __complex__()
2696 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002697
Georg Brandl3ee81df2008-05-17 18:14:43 +00002698- Patch #1623563: allow __class__ assignment for classes with
2699 __slots__. The old and the new class are still required to have the
2700 same slot names.

2706 ``object.__reduce_ex__()`` is called with an object that is faking
2707 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002708
Georg Brandl3ee81df2008-05-17 18:14:43 +00002709- Patch #1680015: Don't modify __slots__ tuple if it contains an

2713
Georg Brandl7b9c5552007-03-12 14:30:05 +00002714- Bug #1678647: write a newline after printing an exception in any
2715 case, even when converting the value to a string failed.
2716
Georg Brandl871f1bc2007-03-12 13:17:36 +00002717- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002718 its argument, if it exists. If not, it will work like before. This
2719 allows customizing the output of dir() in the presence of a
2720 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002721
Collin Winter276887b2007-03-12 16:11:39 +00002722- Patch #922167: Python no longer segfaults when faced with infinitely
2723 self-recursive reload() calls (as reported by bug #742342).
2724
Georg Brandl3ee81df2008-05-17 18:14:43 +00002725- Patch #1675981: remove unreachable code from ``type.__new__()``

2729 parthensized forms. This means complex(repr(x)) now works instead of
2730 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002731
Georg Brandlaa2321b2007-03-07 00:40:28 +00002732- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002733 makes the filenames the warning module prints much more sensible
2734 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002735
Georg Brandl49aafc92007-03-07 00:34:46 +00002736- Variant of patch #697613: don't exit the interpreter on a SystemExit
2737 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002738 variable is given, but break into the interactive interpreter just
2739 like on other exceptions or normal program exit.

2745 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002746
Georg Brandl0fca97a2007-03-05 22:28:08 +00002747- Patch #1674228: when assigning a slice (old-style), check for the
2748 sq_ass_slice instead of the sq_slice slot.
2749
Georg Brandl3ee81df2008-05-17 18:14:43 +00002750- When printing an unraisable error, don't print exceptions. before
2751 the name. This duplicates the behavior whening normally printing
2752 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002753
Georg Brandl3ee81df2008-05-17 18:14:43 +00002754- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Bug #1377858: Fix the segfaulting of the interpreter when an object
2761 created a weakref on itself during a __del__ call for new-style
2762 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003285 AttributeError instead of an IOError when the server's response
3286 didn't contain a valid HTTP status line.

3293 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003294 correctly now.
3295

3375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- unittest now verifies more of its assumptions. In particular,
3377 TestCase and TestSuite subclasses (not instances) are no longer
3378 accepted in TestSuite.addTest(). This should cause no
3379 incompatibility since it never made sense with ordinary subclasses

Georg Brandl3ee81df2008-05-17 18:14:43 +00003662- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3663 with RFC 3207 and forgets any knowledge obtained from the server not
3664 obtained from the TLS negotiation itself. Patch contributed by Bill
3665 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003666
Georg Brandl3ee81df2008-05-17 18:14:43 +00003667- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003668 that the SMTP.starttls() caller no longer needs to call ehlo()
3669 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003670 does not claim to support starttls. Adds the
3671 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3752 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3753 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003770 time so that opening a database previously created with the DB_DUP
3771 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3772 opens. Specifically: dictionary assignment to a DB object will
3773 replace all values for a given key when the database allows
3774 duplicate values. DB users should use DB.put(k, v) when they want
3775 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003776

3782 characters with ASCII value less than 32. Also, it correctly quotes
3783 dots only if they occur on a single line, as opposed to the previous
3784 behavior of quoting dots if they are the second character of any
3785 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003786

Georg Brandl3ee81df2008-05-17 18:14:43 +00004121- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4122 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4123 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004124
4125- Patch #1720595: add T_BOOL to the range of structmember types.
4126

4129
Georg Brandl3ee81df2008-05-17 18:14:43 +00004130- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4131 of w# format code incorrectly truncated the length to an int, even
4132 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4133 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004134
Georg Brandl3ee81df2008-05-17 18:14:43 +00004135- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4136 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004138- PEP 3123: Provide forward compatibility with Python 3.0, while
4139 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4140 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004142- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4143 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004144
4145- Patch #1733960: Allow T_LONGLONG to accept ints.

4152
4153- Fix some leftovers from the conversion from int to Py_ssize_t
4154 (relevant to strings and sequences of more than 2**31 items).
4155
4156- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4157 outside of pystate.c and should not be necessary.
4158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4160 absolute imports. In earlier versions they might have used relative
4161 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004162
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4164 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004165
Georg Brandl3ee81df2008-05-17 18:14:43 +00004166- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004173- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4174 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4175 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4176 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004177
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004191- Removed the macfs module. It had been deprecated since Python 2.5.
4192 This lead to the deprecation of macostools.touched() as it relied
4193 solely on macfs and was a no-op under OS X.
