726 do an explicit seek to the end of file (so that e.g. tell() returns the

728 traditional 2.x file object.

924What's New in Python 2.6.1
925==========================
926
927*Release date: 04-Dec-2008*
928
929Core and Builtins
930-----------------
931
932- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
933 interpreter to abort ("Fatal Python error: Could not reset the stack!")
934 instead of throwing a MemoryError.
935
936- Issue #4367: Python would segfault during compiling when the unicodedata
937 module couldn't be imported and \N escapes were present.
938
939- Issue #4348: Some bytearray methods returned that didn't cause any change to
940 the bytearray, returned the same bytearray instead of a copy.
941
942- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
943
944- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
945
946- Issue #4048: The parser module now correctly validates relative imports.
947
948- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
949 exec statement.
950
951- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
952 method does not return iterators for the 4th and 5th items.
953
954- Issue #4209: Enabling unicode_literals and the print_function in the same
955 __future__ import didn't work.
956
957- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
958 returned a path longer than MAX_PATH. (But It's doubtful this code path is
959 really executed because I cannot move to such directory on win2k)
960
961- Issue #4069: When set.remove(element) is used with a set element, the element
962 is temporarily replaced with an equivalent frozenset. But the eventual
963 KeyError would always report the empty frozenset([]) as the missing key. Now
964 it correctly refers to the initial element.
965
966- Fixed C99 style comments in several files. Python is now C89 compatible
967 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001114- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1115
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001116- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1117 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1118 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1119 ``printf`` function, whereas PyString_FromFormat has an independent
1120 implementation and uses "%zd" on all platforms for size_t values.
1121 This makes a difference on win64, where ``printf`` needs "%Id" to display
1122 64bit values.

1128 object; previously an int would be returned for small values. the __long__
1129 method is allowed to return either an int or a long, but the behaviour of
1130 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001132- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001138 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001139 was correctly parsed but parsing of subsequent arguments failed.
1140
Vinay Sajip35e3b032008-09-01 14:33:59 +00001141- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001142 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1143 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1144 when given a tuple of classes as second argument, were looking up
1145 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1146 type object.
1147
Neal Norwitz18aa3882008-08-24 05:04:52 +00001148- Fix crashes on memory allocation failure found with failmalloc.

1288-----------------
1289
Guido van Rossumf8402962008-08-20 15:01:50 +00001290- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1291 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1292 extensions do not automatically benefit from the class attribute
1293 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1294 to their tp_flags field if they care. This is a backwards
1295 compatibility feature; in 3.0, all types will use the cache by
1296 default.
1297
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001298- Keyword arguments can now follow starred arguments. (``f(a, *args,

Georg Brandl1e13ea92008-08-11 09:07:59 +00001308- Issue #3537: Fix an assertion failure when an empty but presized dict
1309 object was stored in the freelist.
1310
Mark Dickinsonb6467572008-08-04 21:30:09 +00001311- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1312 ValueError consistently across platforms.
1313
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001314- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1315 (64bit Unix, for example), unichr() would truncate its argument and return
1316 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1317
Neal Norwitze7d8be82008-07-31 17:17:14 +00001318- Apply security patches from Apple.
1319
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001320- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1321 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1322
Antoine Pitrou92f82162008-07-25 22:22:08 +00001323- Issue #1819: function calls with several named parameters are now on
1324 average 35% faster (as measured by pybench).
1325
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001326- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1327 the python debugger steps into a class statement: the free variables (local
1328 variables defined in an outer scope) would be deleted from the outer scope.
1329
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001330- Issue #2620: Overflow checking when allocating or reallocating memory
1331 was not always being done properly in some python types and extension
1332 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1333 all been updated to perform better checks and places in the code that
1334 would previously leak memory on the error path when such an allocation
1335 failed have been fixed.

1341
Benjamin Petersone977ad42008-08-20 01:42:01 +00001342- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1343 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1344
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001345- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1346 version reported by these tools does not necessarily follow the python
1347 version numbering scheme, so the module is less strict when parsing it.
1348
Nick Coghlanf70385a2008-08-18 12:42:46 +00001349- Issue #2235: Added Py3k warnings for types which will become unhashable
1350 under the stricter __hash__ inheritance rules in 3.0. Several types
1351 which did not meet the rules for hash invariants and were already
1352 unhashable in 3.0 have now been explicitly flagged as unhashable in
1353 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1354 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1355
Brett Cannon88f801d2008-08-18 00:46:22 +00001356- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1357 imported into the module but exposed as part of the module's API.
1358

1364
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001365- Issue #3575: Incremental decoder's decode function now takes bytearray
1366 by using 's*' instead of 't#'.
1367
Jesus Cea585ad8a2009-07-02 15:37:21 +00001368- Issue #2222: Fixed reference leak when occurred os.rename()

Facundo Batistaeb90b782008-08-16 14:44:07 +00001377- Issue #2776: fixed small issue when handling an URL with double slash
1378 after a 302 response in the case of not going through a proxy.
1379
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001380- Issue #2676: in the email package, content-type parsing was hanging on
1381 pathological input because of quadratic or exponential behaviour of a
1382 regular expression.
1383
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001384- Issue #3476: binary buffered reading through the new "io" library is now
1385 thread-safe.
1386
Brett Cannonbf3157b2008-08-14 05:00:03 +00001387- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1388 since mimetools itself is deprecated. Because modules are cached, all
1389 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1390
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001391- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001393- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1394 menu entries were not deleted.
1395
Brett Cannon83e81842008-08-09 23:30:55 +00001396- Copied the implementation of reduce() to _functools.reduce() to have a
1397 version that did not raise a DeprecationWarning under -3.
1398
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001399- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1400 a MemoryError rather than silently stop the iteration.
1401
Guido van Rossum59ce9012008-08-09 14:55:34 +00001402- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1403 to _sre.compile() will now be rejected. This should not affect anybody
1404 since the re.compile() function never generates invalid re-bytecode.
1405
Skip Montanaroa032bf42008-08-08 22:52:51 +00001406- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1407 upon first access it can be automatically initialized from the csv file if
1408 it wasn't initialized during instantiation.
1409
Brett Cannon3aa2a492008-08-06 22:28:09 +00001410- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1411 the reload() built-in has been removed.
1412
Brett Cannon7e30b672008-08-04 21:52:25 +00001413- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001414 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1422 raised an AttributeError.
1423
Benjamin Peterson01a24322008-07-28 23:35:27 +00001424- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001425 asking for a specific length. This problem only affected files opened
1426 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001427

1450
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001451- Issue #3394: zipfile.writestr sets external attributes when passed a
1452 file name rather than a ZipInfo instance, so files are extracted with
1453 mode 0600 rather than 000 under Unix.
1454
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001455- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1456 argument in python 2.5, this broke code that subclassed Popen to include its
1457 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1466
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001467- Issue #2235: the C API function PyObject_HashNotImplemented and its
1468 interaction with the tp_hash slot (added in 2.6b2) are now documented
1469
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001470- Issue #643841: The language reference now provides more detailed
1471 coverage of the lookup process for special methods. The disclaimers
1472 regarding lack of coverage of new-style classes have also been
1473 removed, since the coverage is now fairly reasonable.

1477================================
1478
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001479*Release date: 17-Jul-2008*
1480
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001481Core and Builtins
1482-----------------
1483
Georg Brandl3e483f62008-07-16 22:57:41 +00001484- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1485 its methods now allow for items objects that can be converted to
1486 an integer using operator.index().
1487
Mark Dickinson64b7e502008-07-16 09:40:03 +00001488- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1489 produced a ValueError instead of giving the correct float.
1490
Eric Smitha5fa5a22008-07-16 00:11:49 +00001491- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1492 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1493
Mark Dickinson7103aa42008-07-15 19:08:33 +00001494- Issue #3008: the float type has a new instance method 'float.hex'
1495 and a new class method 'float.fromhex' to convert floating-point
1496 numbers to and from hexadecimal strings, respectively.
1497
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001498- Issue #2235: __hash__ is once again inherited by default. To allow
1499 collections.Hashable to remain meaningful in the presence of the
1500 default hash implementation (object.__hash__), it is now possible
1501 to explicit block inheritance of hash by setting __hash__=None at
1502 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1503 level.
1504
Nick Coghlanb028f502008-07-13 14:52:36 +00001505- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1506 the parent module cannot be found while performing an absolute import.
1507 This means that an incorrectly defined __package__ attribute will
1508 now only prevent relative imports in that module rather than causing
1509 all imports from that module to fail.
1510
Nick Coghlan14ff9942008-07-08 14:21:42 +00001511- Issue #2517: Allow unicode messages in Exceptions again by correctly
1512 bypassing the instance dictionary when looking up __unicode__ on
1513 new-style classes.
1514
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001515- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1516 set to a custom object whose write() method happens to install
1517 another file in sys.stdout.
1518
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001519- Issue #3088: Corrected a race condition in classes derived from
1520 threading.local: the first member set by a thread could be saved in
1521 another thread's dictionary.
1522
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001523- Issue #3004: Minor change to slice.indices(): the start and stop
1524 arguments are now treated identically, making the behaviour easier
1525 to describe and understand. For example, slice(None, -10,
1526 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1527 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1528 10, -1).
1529
Georg Brandl278fc502008-07-19 12:46:12 +00001530- Issue #3219: Calling a function with repeated keyword arguments,
1531 f(a=2, a=23), would not cause a syntax error. This was a regression
1532 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001533
Georg Brandl278fc502008-07-19 12:46:12 +00001534- Issue #2862: Make int and float freelist management consistent with
1535 other freelists. Changes their CompactFreeList apis into
1536 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001537

1539-------
1540
Thomas Heller57adf222008-08-14 19:10:48 +00001541- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1542 api functions without holding the GIL, which could lead to a fatal
1543 error when they failed.
1544
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001545- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001553- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1554 ForkingPickler.register() to resolve conflict with ctypes.
1555
Vinay Sajip51e65192008-07-18 09:01:10 +00001556- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001557
Thomas Heller880f5292008-07-15 19:39:38 +00001558- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1559 a valid dlerror() message.
1560
Thomas Heller2bad6572008-07-15 17:19:50 +00001561- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1562 incomplete structure was created.
1563
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001564- Issue #3339: dummy_thread.acquire() should not return None.
1565
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001566- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1567
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001568- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001569
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001570- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1571 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001572 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001573 content-length. The problem had been corrected in the 2.4 branch, but never
1574 merged into trunk.
1575
Georg Brandle78fbcc2008-07-05 10:13:36 +00001576- Issue #2663: add filtering capability to shutil.copytree().

1580- Issue #1526: Allow more than 64k files to be added to Zip64 file.
1581
1582- Issue #1746: Correct handling of zipfile archive comments (previously
1583 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001584 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001585
Vinay Sajip51e65192008-07-18 09:01:10 +00001586- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001587 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001588
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001589- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00001982 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001983
1984 This is controlled by the configure argument ``--with-universal-archs``:

1986 - ``--with-universal-archs=all``: install 4-way universal
1987
1988 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1989

Georg Brandl3ee81df2008-05-17 18:14:43 +00002044- Issue #1631171: Re-implement the 'warnings' module in C (the
2045 original Python code has been kept as backup). This will allow for
2046 using the 'warning's machinery in such places as the parser where
2047 use of pure Python code is not possible. Both the ``showarning()``
2048 and ``formatwarning()`` gain an optional 'line' argument which is
2049 not called by default for backwards-compatibility reasons. Setting
2050 ``warnings.showwarning()`` to an implementation that lacks support
2051 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002114- Issue #2550: The approach used by client/server code for obtaining
2115 ports to listen on in network-oriented tests has been refined in an
2116 effort to facilitate running multiple instances of the entire
2117 regression test suite in parallel without issue.
2118 test_support.bind_port() has been fixed such that it will always
2119 return a unique port -- which wasn't always the case with the
2120 previous implementation, especially if socket options had been set
2121 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2122 new implementation of bind_port() will actually raise an exception
2123 if it is passed an AF_INET/SOCK_STREAM socket with either the
2124 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2125 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2126 the socket it's been passed. This currently only applies to
2127 Windows. This option prevents any other sockets from binding to the
2128 host/port we've bound to, thus removing the possibility of the
2129 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2130 when a second SOCK_STREAM socket binds and accepts to a host/port
2131 that's already been bound by another socket. The optional preferred
2132 port parameter to bind_port() has been removed. Under no
2133 circumstances should tests be hard coding ports!
2134
2135 test_support.find_unused_port() has also been introduced, which will
2136 pass a temporary socket object to bind_port() in order to obtain an
2137 unused port. The temporary socket object is then closed and
2138 deleted, and the port is returned. This method should only be used
2139 for obtaining an unused port in order to pass to an external program
2140 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2141 a parameter to a server-oriented class that doesn't give you direct
2142 access to the underlying socket used.
2143
2144 Finally, test_support.HOST has been introduced, which should be used
2145 for the host argument of any relevant socket calls (i.e. bind and
2146 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002147
2148 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002149 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002150 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2151 test_asynchat and test_socket_ssl.
2152
Georg Brandl3ee81df2008-05-17 18:14:43 +00002153 It is now possible for multiple instances of the regression test
2154 suite to run in parallel without issue.

2420Core and builtins
2421-----------------
2422
Fred Drakea8ee94b2008-03-01 02:45:07 +00002423- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002424 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002425
Georg Brandlad61bc82008-02-23 15:11:18 +00002426- Issue #2067: file.__exit__() now calls subclasses' close() method.
2427
2428- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002429
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002430- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002431 issue 215555 for a discussion.
2432
Eric Smitha73fbe72008-02-23 03:09:44 +00002433- Added the future_builtins module, which contains hex() and oct().
2434 These are the PEP 3127 version of these functions, designed to be
2435 compatible with the hex() and oct() builtins from Python 3.0. They
2436 differ slightly in their output formats from the existing, unchanged
2437 Python 2.6 builtins. The expected usage of the future_builtins
2438 module is:
2439 from future_builtins import hex, oct
2440
Eric Smith7ef40bf2008-02-20 23:34:22 +00002441- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2442 exponents for exponents with absolute value < 100. Follows C99
2443 standard. This is a change on Windows, which would use 3 digits.
2444 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2445 so that any alterations it does to the resulting string will be
2446 available in stringlib/formatter.h (for float.__format__).
2447
Eric Smith5a3c1352008-02-19 13:21:56 +00002448- Implemented PEP 3101, Advanced String Formatting. This adds a new
2449 builtin format(); a format() method for str and unicode; a
2450 __format__() method to object, str, unicode, int, long, float, and
2451 datetime; the class string.Formatter; and the C API
2452 PyObject_Format().
2453
Georg Brandl3ee81df2008-05-17 18:14:43 +00002454- Fixed several potential crashes, all caused by specially crafted
2455 __del__ methods exploiting objects in temporarily inconsistent
2456 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002457
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002458- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002459 prevent a possible crash: an Abstract Base Class would try to access
2460 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002461
Georg Brandl3ee81df2008-05-17 18:14:43 +00002462- Fixed repr() and str() of complex numbers with infinity or nan as
2463 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002464
Georg Brandl3ee81df2008-05-17 18:14:43 +00002465- Clear all free lists during a gc.collect() of the highest generation
2466 in order to allow pymalloc to free more arenas. Python may give back
2467 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002468
Georg Brandl3ee81df2008-05-17 18:14:43 +00002469- Issue #2045: Fix an infinite recursion triggered when printing a
2470 subclass of collections.defaultdict, if its default_factory is set
2471 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002472
Christian Heimesf75dbef2008-02-08 00:11:31 +00002473- Fixed a minor memory leak in dictobject.c. The content of the free
2474 list was not freed on interpreter shutdown.
2475
Georg Brandl3ee81df2008-05-17 18:14:43 +00002476- Limit free list of method and builtin function objects to 256
2477 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002478
Georg Brandl3ee81df2008-05-17 18:14:43 +00002479- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2480 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002481 to compact the internal free lists of pre-allocted ints and floats.
2482
Georg Brandl3ee81df2008-05-17 18:14:43 +00002483- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2484 calls. Python expected the return type int but the fork familie
2485 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002486
Georg Brandl3ee81df2008-05-17 18:14:43 +00002487- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2488 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002489
Georg Brandl3ee81df2008-05-17 18:14:43 +00002490- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2491 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002492
Georg Brandl3ee81df2008-05-17 18:14:43 +00002493- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2494 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002495
Georg Brandl3ee81df2008-05-17 18:14:43 +00002496- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2497 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002498
Georg Brandl3ee81df2008-05-17 18:14:43 +00002499- Patch #1473257: generator objects gain a gi_code attribute. This is
2500 the same object as the func_code attribute of the function that
2501 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002502
Georg Brandl3ee81df2008-05-17 18:14:43 +00002503- Issue #1920: "while 0" statements were completely removed by the
2504 compiler, even in the presence of an "else" clause, which is
2505 supposed to be run when the condition is false. Now the compiler
2506 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002507
Guido van Rossumeead05f2008-01-24 18:21:02 +00002508- A few crashers fixed: weakref_in_del.py (issue #1377858);
2509 loosing_dict_ref.py (issue #1303614, test67.py);
2510 borrowed_ref_[34].py (not in tracker).
2511
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002512- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002513 suppressed while an extension is loaded by calling SetErrorMode in
2514 dynload_win.c. The error is still reported properly.
2515
Georg Brandl3ee81df2008-05-17 18:14:43 +00002516- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002517 several extension methods and modules do not work without unicode
2518 support.
2519
Georg Brandl26543b12008-01-21 18:36:51 +00002520- Issue #1882: when compiling code from a string, encoding cookies in the
2521 second line of code were not always recognized correctly.
2522
Georg Brandl14404b62008-01-19 19:27:05 +00002523- Issue #1679: "0x" was taken as a valid integer literal.
2524
Georg Brandl6caad7d2008-01-26 14:19:22 +00002525- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002526 added.
2527
Christian Heimesc94e2b52008-01-14 04:13:37 +00002528- sys.float_info / PyFloat_GetInfo: The floating point information
2529 object was converted from a dict to a specialized structseq object.
2530
Georg Brandl3ee81df2008-05-17 18:14:43 +00002531- Patch #1816: Added sys.flags structseq. It exposes the status of
2532 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002533
Georg Brandl3ee81df2008-05-17 18:14:43 +00002534- Objects/structseq.c: Implemented new structseq representation. The
2535 patch makes structseqs (e.g. the return value of os.stat) more
2536 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002537
Georg Brandl3ee81df2008-05-17 18:14:43 +00002538- Patch #1700288: added a type attribute cache that caches method
2539 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002540
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002541- Bug #1776: __import__() no longer accepts filenames on any platform.
2542 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002543
Georg Brandlaed6c662008-01-07 17:25:53 +00002544- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2545
Georg Brandl3ee81df2008-05-17 18:14:43 +00002546- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2547 envvar and sys.dont_write_bytecode attribute. All these can be set
2548 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002549
Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Improve some exception messages when Windows fails to load an
2551 extension module. Now we get for example '%1 is not a valid Win32
2552 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002553
Georg Brandl3ee81df2008-05-17 18:14:43 +00002554- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00002555
Georg Brandl3ee81df2008-05-17 18:14:43 +00002556- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2557 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002558
Christian Heimes0a8143f2007-12-18 23:22:54 +00002559- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002560 and INF. float("nan"), float("inf") and float("-inf") now work on
2561 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002562
Georg Brandl3ee81df2008-05-17 18:14:43 +00002563- Compiler now generates simpler and faster code for dictionary
2564 literals. The oparg for BUILD_MAP now indicates an estimated
2565 dictionary size. There is a new opcode, STORE_MAP, for adding
2566 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002567
Georg Brandl3ee81df2008-05-17 18:14:43 +00002568- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002570- Issue #1620: New property decorator syntax was modifying the
2571 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002572
Georg Brandl3ee81df2008-05-17 18:14:43 +00002573- Issue #1538: Avoid copying string in split/rsplit if the split char
2574 is not found.

2581 __package__ attribute.
2582
Georg Brandl3ee81df2008-05-17 18:14:43 +00002583- Issue #1402: Fix a crash on exit, when another thread is still
2584 running, and if the deallocation of its frames somehow calls the
2585 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002586

2596 file can now be directly executed by passing their name to the
2597 interpreter. The directory/zipfile is automatically inserted as the
2598 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002599
Georg Brandl3ee81df2008-05-17 18:14:43 +00002600- Issue #1265: Fix a problem with sys.settrace, if the tracing
2601 function uses a generator expression when at the same time the
2602 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002603
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002604- sets and frozensets now have an isdisjoint() method.
2605
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002606- optimize the performance of builtin.sum().
2607
Neal Norwitz44f326e2007-10-05 05:29:17 +00002608- Fix warnings found by the new version of the Coverity checker.
2609
Georg Brandl3ee81df2008-05-17 18:14:43 +00002610- The enumerate() builtin function is no longer bounded to sequences
2611 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2612 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002613
Georg Brandl3ee81df2008-05-17 18:14:43 +00002614- Issue #1686386: Tuple's tp_repr did not take into account the
2615 possibility of having a self-referential tuple, which is possible
2616 from C code. Nor did object's tp_str consider that a type's tp_str
2617 could do something that could lead to an inifinite recursion.
2618 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2619 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002620
Georg Brandl3ee81df2008-05-17 18:14:43 +00002621- Issue #1164: It was possible to trigger deadlock when using the
2622 'print' statement to write to a file since the GIL was not released
2623 as needed. Now PyObject_Print() does the right thing along with
2624 various tp_print implementations of the built-in types and those in
2625 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002627- Issue #1147: Exceptions were directly allowing string exceptions in
2628 their throw() method even though string exceptions no longer
2629 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002630
Georg Brandl3ee81df2008-05-17 18:14:43 +00002631- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002634- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002635 PyObject_Call() never calling back out to Python code to trigger
2636 recursion depth updates/checks. Required the creation of a static
2637 RuntimeError instance in case normalizing an exception put the
2638 recursion check value past its limit. Fixes crashers
2639 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002654- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002655 __*__ attributes. (Some already existed, e.g., __doc__ and
2656 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002657
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002658- Add -3 option to the interpreter to warn about features that are
2659 deprecated and will be changed/removed in Python 3.0.
2660

2662 calls.
2663
Collin Winter62903052007-05-18 23:11:24 +00002664- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002665 "except E as target:". This is to provide forwards compatibility
2666 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002667
Brett Cannon229cee22007-05-05 01:34:02 +00002668- Deprecate BaseException.message as per PEP 352.
2669
Georg Brandl3ee81df2008-05-17 18:14:43 +00002670- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002671 inherited from a builtin base.
2672
Vinay Sajip8549ce32007-05-06 17:53:37 +00002673- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002674 setting a plain string, ie don't expand to single letter identifiers.
2675
Raymond Hettinger13936692007-04-11 18:40:58 +00002676- Request #1191699: Slices can now be pickled.
2677
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002678- Request #1193128: str.translate() now allows a None argument for
2679 translations that only remove characters without re-mapping the
2680 remaining characters.
2681
Georg Brandl5cb76c12007-03-21 09:00:39 +00002682- Patch #1682205: a TypeError while unpacking an iterable is no longer
2683 masked by a generic one with the message "unpack non-sequence".
2684
Neal Norwitzaa754b72007-03-21 06:39:48 +00002685- Remove unused file Python/fmod.c.
2686
Guido van Rossum143b5642007-03-23 04:58:42 +00002687- Bug #1683368: The object.__init__() and object.__new__() methods are
2688 now stricter in rejecting excess arguments. The only time when
2689 either allows excess arguments is when it is not overridden and the
2690 other one is. For backwards compatibility, when both are
2691 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002692 warning later). Also, type.__init__() insists on the same signature
2693 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002694
Georg Brandl3ee81df2008-05-17 18:14:43 +00002695- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2696 object to complex using its __complex__() method before falling back
2697 to the __float__() method. Therefore, the functions in the cmath
2698 module now can operate on objects that define a __complex__()
2699 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Patch #1623563: allow __class__ assignment for classes with
2702 __slots__. The old and the new class are still required to have the
2703 same slot names.

2716
Georg Brandl7b9c5552007-03-12 14:30:05 +00002717- Bug #1678647: write a newline after printing an exception in any
2718 case, even when converting the value to a string failed.
2719
Georg Brandl871f1bc2007-03-12 13:17:36 +00002720- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002721 its argument, if it exists. If not, it will work like before. This
2722 allows customizing the output of dir() in the presence of a
2723 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002724
Collin Winter276887b2007-03-12 16:11:39 +00002725- Patch #922167: Python no longer segfaults when faced with infinitely
2726 self-recursive reload() calls (as reported by bug #742342).
2727
Georg Brandl3ee81df2008-05-17 18:14:43 +00002728- Patch #1675981: remove unreachable code from ``type.__new__()``

2732 parthensized forms. This means complex(repr(x)) now works instead of
2733 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002734
Georg Brandlaa2321b2007-03-07 00:40:28 +00002735- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002736 makes the filenames the warning module prints much more sensible
2737 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002738
Georg Brandl49aafc92007-03-07 00:34:46 +00002739- Variant of patch #697613: don't exit the interpreter on a SystemExit
2740 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002741 variable is given, but break into the interactive interpreter just
2742 like on other exceptions or normal program exit.

2748 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002749
Georg Brandl0fca97a2007-03-05 22:28:08 +00002750- Patch #1674228: when assigning a slice (old-style), check for the
2751 sq_ass_slice instead of the sq_slice slot.
2752
Georg Brandl3ee81df2008-05-17 18:14:43 +00002753- When printing an unraisable error, don't print exceptions. before
2754 the name. This duplicates the behavior whening normally printing
2755 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002756
Georg Brandl3ee81df2008-05-17 18:14:43 +00002757- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00002763- Bug #1377858: Fix the segfaulting of the interpreter when an object
2764 created a weakref on itself during a __del__ call for new-style
2765 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003288 AttributeError instead of an IOError when the server's response
3289 didn't contain a valid HTTP status line.

3378
Georg Brandl3ee81df2008-05-17 18:14:43 +00003379- unittest now verifies more of its assumptions. In particular,
3380 TestCase and TestSuite subclasses (not instances) are no longer
3381 accepted in TestSuite.addTest(). This should cause no
3382 incompatibility since it never made sense with ordinary subclasses

3663 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003664
Georg Brandl3ee81df2008-05-17 18:14:43 +00003665- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3666 with RFC 3207 and forgets any knowledge obtained from the server not
3667 obtained from the TLS negotiation itself. Patch contributed by Bill
3668 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003669
Georg Brandl3ee81df2008-05-17 18:14:43 +00003670- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003671 that the SMTP.starttls() caller no longer needs to call ehlo()
3672 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003673 does not claim to support starttls. Adds the
3674 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3755 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3756 silently miscode subclasses of those types. Now, it raises a
3757 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003758

Georg Brandl3ee81df2008-05-17 18:14:43 +00003773 time so that opening a database previously created with the DB_DUP
3774 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3775 opens. Specifically: dictionary assignment to a DB object will
3776 replace all values for a given key when the database allows
3777 duplicate values. DB users should use DB.put(k, v) when they want
3778 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003779

3785 characters with ASCII value less than 32. Also, it correctly quotes
3786 dots only if they occur on a single line, as opposed to the previous
3787 behavior of quoting dots if they are the second character of any
3788 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003789

Georg Brandl3ee81df2008-05-17 18:14:43 +00004124- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4125 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4126 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004127
4128- Patch #1720595: add T_BOOL to the range of structmember types.
4129

4132
Georg Brandl3ee81df2008-05-17 18:14:43 +00004133- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4134 of w# format code incorrectly truncated the length to an int, even
4135 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4136 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004137
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4139 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004141- PEP 3123: Provide forward compatibility with Python 3.0, while
4142 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4143 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004145- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4146 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004147
4148- Patch #1733960: Allow T_LONGLONG to accept ints.

4155
4156- Fix some leftovers from the conversion from int to Py_ssize_t
4157 (relevant to strings and sequences of more than 2**31 items).
4158
4159- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4160 outside of pystate.c and should not be necessary.
4161
Georg Brandl3ee81df2008-05-17 18:14:43 +00004162- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4163 absolute imports. In earlier versions they might have used relative
4164 imports under some conditions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004166- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4167 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004168
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004176- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4177 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4178 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4179 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004180
Georg Brandl3ee81df2008-05-17 18:14:43 +00004181- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004194- Removed the macfs module. It had been deprecated since Python 2.5.
4195 This lead to the deprecation of macostools.touched() as it relied
4196 solely on macfs and was a no-op under OS X.
