904What's New in Python 2.6.1
905==========================
906
907*Release date: 04-Dec-2008*
908
909Core and Builtins
910-----------------
911
912- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
913 interpreter to abort ("Fatal Python error: Could not reset the stack!")
914 instead of throwing a MemoryError.
915
916- Issue #4367: Python would segfault during compiling when the unicodedata
917 module couldn't be imported and \N escapes were present.
918
919- Issue #4348: Some bytearray methods returned that didn't cause any change to
920 the bytearray, returned the same bytearray instead of a copy.
921
922- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
923
924- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
925
926- Issue #4048: The parser module now correctly validates relative imports.
927
928- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
929 exec statement.
930
931- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
932 method does not return iterators for the 4th and 5th items.
933
934- Issue #4209: Enabling unicode_literals and the print_function in the same
935 __future__ import didn't work.
936
937- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
938 returned a path longer than MAX_PATH. (But It's doubtful this code path is
939 really executed because I cannot move to such directory on win2k)
940
941- Issue #4069: When set.remove(element) is used with a set element, the element
942 is temporarily replaced with an equivalent frozenset. But the eventual
943 KeyError would always report the empty frozenset([]) as the missing key. Now
944 it correctly refers to the initial element.
945
946- Fixed C99 style comments in several files. Python is now C89 compatible
947 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001094- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1095
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001096- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1097 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1098 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1099 ``printf`` function, whereas PyString_FromFormat has an independent
1100 implementation and uses "%zd" on all platforms for size_t values.
1101 This makes a difference on win64, where ``printf`` needs "%Id" to display
1102 64bit values.
1103
Benjamin Peterson97179b02008-09-09 20:55:01 +00001104- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1108 object; previously an int would be returned for small values. the __long__
1109 method is allowed to return either an int or a long, but the behaviour of
1110 float objects should not change to respect backward compatibility.
1111
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001112- Issue #3751: str.rpartition would perform a left-partition when called with
1113 a unicode argument.
1114
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001115- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001118 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001119 was correctly parsed but parsing of subsequent arguments failed.
1120
Vinay Sajip35e3b032008-09-01 14:33:59 +00001121- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001122 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1123 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1124 when given a tuple of classes as second argument, were looking up
1125 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1126 type object.
1127
Neal Norwitz18aa3882008-08-24 05:04:52 +00001128- Fix crashes on memory allocation failure found with failmalloc.
1129
1130- Fix memory leaks found with valgrind and update suppressions file.
1131
1132- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1133
1134- Fix problem using wrong name in decimal module reported by pychecker.

1167
Vinay Sajip844f7412008-09-09 13:42:08 +00001168- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.

Nick Coghland2e09382008-09-11 12:11:06 +00001170- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001171 return a list or None rather than a custom object.

1197 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1198 for catch_warnings() also led to an improvement in the raising of a
1199 DeprecationWarning related to warnings.warn_explicit().

1268-----------------
1269
Guido van Rossumf8402962008-08-20 15:01:50 +00001270- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1271 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1272 extensions do not automatically benefit from the class attribute
1273 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1274 to their tp_flags field if they care. This is a backwards
1275 compatibility feature; in 3.0, all types will use the cache by
1276 default.
1277
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001278- Keyword arguments can now follow starred arguments. (``f(a, *args,
1279 keyword=23)`` is now valid syntax.)
1280
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001281- ctypes function pointers that are COM methods have a boolean True
1282 value again.

1286 and introducing s*.
1287
Georg Brandl1e13ea92008-08-11 09:07:59 +00001288- Issue #3537: Fix an assertion failure when an empty but presized dict
1289 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00001291- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1292 ValueError consistently across platforms.
1293
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001294- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1295 (64bit Unix, for example), unichr() would truncate its argument and return
1296 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1297
Neal Norwitze7d8be82008-07-31 17:17:14 +00001298- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001300- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1301 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1302
Antoine Pitrou92f82162008-07-25 22:22:08 +00001303- Issue #1819: function calls with several named parameters are now on
1304 average 35% faster (as measured by pybench).
1305
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001306- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1307 the python debugger steps into a class statement: the free variables (local
1308 variables defined in an outer scope) would be deleted from the outer scope.
1309
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001310- Issue #2620: Overflow checking when allocating or reallocating memory
1311 was not always being done properly in some python types and extension
1312 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1313 all been updated to perform better checks and places in the code that
1314 would previously leak memory on the error path when such an allocation
1315 failed have been fixed.

1321
Benjamin Petersone977ad42008-08-20 01:42:01 +00001322- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1323 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1324
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001325- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1326 version reported by these tools does not necessarily follow the python
1327 version numbering scheme, so the module is less strict when parsing it.
1328
Nick Coghlanf70385a2008-08-18 12:42:46 +00001329- Issue #2235: Added Py3k warnings for types which will become unhashable
1330 under the stricter __hash__ inheritance rules in 3.0. Several types
1331 which did not meet the rules for hash invariants and were already
1332 unhashable in 3.0 have now been explicitly flagged as unhashable in
1333 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1334 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1335
Brett Cannon88f801d2008-08-18 00:46:22 +00001336- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1346 by using 's*' instead of 't#'.
1347
Jesus Cea585ad8a2009-07-02 15:37:21 +00001348- Issue #2222: Fixed reference leak when occurred os.rename()

1358 after a 302 response in the case of not going through a proxy.
1359
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001360- Issue #2676: in the email package, content-type parsing was hanging on
1361 pathological input because of quadratic or exponential behaviour of a
1362 regular expression.
1363
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001364- Issue #3476: binary buffered reading through the new "io" library is now
1365 thread-safe.
1366
Brett Cannonbf3157b2008-08-14 05:00:03 +00001367- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1368 since mimetools itself is deprecated. Because modules are cached, all
1369 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1370
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001371- Issue #3134: shutil referenced undefined WindowsError symbol.

1374 menu entries were not deleted.
1375
Brett Cannon83e81842008-08-09 23:30:55 +00001376- Copied the implementation of reduce() to _functools.reduce() to have a
1377 version that did not raise a DeprecationWarning under -3.
1378
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001379- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1380 a MemoryError rather than silently stop the iteration.
1381
Guido van Rossum59ce9012008-08-09 14:55:34 +00001382- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1383 to _sre.compile() will now be rejected. This should not affect anybody
1384 since the re.compile() function never generates invalid re-bytecode.
1385
Skip Montanaroa032bf42008-08-08 22:52:51 +00001386- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1387 upon first access it can be automatically initialized from the csv file if
1388 it wasn't initialized during instantiation.
1389
Brett Cannon3aa2a492008-08-06 22:28:09 +00001390- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1391 the reload() built-in has been removed.
1392
Brett Cannon7e30b672008-08-04 21:52:25 +00001393- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001394 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1402 raised an AttributeError.
1403
Benjamin Peterson01a24322008-07-28 23:35:27 +00001404- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001405 asking for a specific length. This problem only affected files opened
1406 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001407

1430
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001431- Issue #3394: zipfile.writestr sets external attributes when passed a
1432 file name rather than a ZipInfo instance, so files are extracted with
1433 mode 0600 rather than 000 under Unix.
1434
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001435- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1436 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001447- Issue #2235: the C API function PyObject_HashNotImplemented and its
1448 interaction with the tp_hash slot (added in 2.6b2) are now documented
1449
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001450- Issue #643841: The language reference now provides more detailed
1451 coverage of the lookup process for special methods. The disclaimers
1452 regarding lack of coverage of new-style classes have also been
1453 removed, since the coverage is now fairly reasonable.

1457================================
1458
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001459*Release date: 17-Jul-2008*
1460
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001461Core and Builtins
1462-----------------
1463
Georg Brandl3e483f62008-07-16 22:57:41 +00001464- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1465 its methods now allow for items objects that can be converted to
1466 an integer using operator.index().
1467
Mark Dickinson64b7e502008-07-16 09:40:03 +00001468- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1469 produced a ValueError instead of giving the correct float.
1470
Eric Smitha5fa5a22008-07-16 00:11:49 +00001471- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1472 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1473
Mark Dickinson7103aa42008-07-15 19:08:33 +00001474- Issue #3008: the float type has a new instance method 'float.hex'
1475 and a new class method 'float.fromhex' to convert floating-point
1476 numbers to and from hexadecimal strings, respectively.
1477
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001478- Issue #2235: __hash__ is once again inherited by default. To allow
1479 collections.Hashable to remain meaningful in the presence of the
1480 default hash implementation (object.__hash__), it is now possible
1481 to explicit block inheritance of hash by setting __hash__=None at
1482 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1483 level.
1484
Nick Coghlanb028f502008-07-13 14:52:36 +00001485- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1486 the parent module cannot be found while performing an absolute import.
1487 This means that an incorrectly defined __package__ attribute will
1488 now only prevent relative imports in that module rather than causing
1489 all imports from that module to fail.
1490
Nick Coghlan14ff9942008-07-08 14:21:42 +00001491- Issue #2517: Allow unicode messages in Exceptions again by correctly
1492 bypassing the instance dictionary when looking up __unicode__ on
1493 new-style classes.
1494
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001495- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1496 set to a custom object whose write() method happens to install
1497 another file in sys.stdout.
1498
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001499- Issue #3088: Corrected a race condition in classes derived from
1500 threading.local: the first member set by a thread could be saved in
1501 another thread's dictionary.
1502
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001503- Issue #3004: Minor change to slice.indices(): the start and stop
1504 arguments are now treated identically, making the behaviour easier
1505 to describe and understand. For example, slice(None, -10,
1506 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1507 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1508 10, -1).
1509
Georg Brandl278fc502008-07-19 12:46:12 +00001510- Issue #3219: Calling a function with repeated keyword arguments,
1511 f(a=2, a=23), would not cause a syntax error. This was a regression
1512 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001513
Georg Brandl278fc502008-07-19 12:46:12 +00001514- Issue #2862: Make int and float freelist management consistent with
1515 other freelists. Changes their CompactFreeList apis into
1516 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001517

Thomas Heller57adf222008-08-14 19:10:48 +00001521- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1522 api functions without holding the GIL, which could lead to a fatal
1523 error when they failed.
1524
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001525- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001533- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1534 ForkingPickler.register() to resolve conflict with ctypes.
1535
Vinay Sajip51e65192008-07-18 09:01:10 +00001536- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001537
Thomas Heller880f5292008-07-15 19:39:38 +00001538- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1539 a valid dlerror() message.
1540
Thomas Heller2bad6572008-07-15 17:19:50 +00001541- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1542 incomplete structure was created.
1543

1547
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001548- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001549
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001550- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1551 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001552 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001553 content-length. The problem had been corrected in the 2.4 branch, but never
1554 merged into trunk.
1555
Georg Brandle78fbcc2008-07-05 10:13:36 +00001556- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001569- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1570 handling is now the same as that of other special attributes like __name__).
1571
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001572- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1573 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00001962 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001963
1964 This is controlled by the configure argument ``--with-universal-archs``:
1965
1966 - ``--with-universal-archs=all``: install 4-way universal
1967
1968 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1969
1970 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1971
1972 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002024- Issue #1631171: Re-implement the 'warnings' module in C (the
2025 original Python code has been kept as backup). This will allow for
2026 using the 'warning's machinery in such places as the parser where
2027 use of pure Python code is not possible. Both the ``showarning()``
2028 and ``formatwarning()`` gain an optional 'line' argument which is
2029 not called by default for backwards-compatibility reasons. Setting
2030 ``warnings.showwarning()`` to an implementation that lacks support
2031 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002094- Issue #2550: The approach used by client/server code for obtaining
2095 ports to listen on in network-oriented tests has been refined in an
2096 effort to facilitate running multiple instances of the entire
2097 regression test suite in parallel without issue.
2098 test_support.bind_port() has been fixed such that it will always
2099 return a unique port -- which wasn't always the case with the
2100 previous implementation, especially if socket options had been set
2101 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2102 new implementation of bind_port() will actually raise an exception
2103 if it is passed an AF_INET/SOCK_STREAM socket with either the
2104 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2105 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2106 the socket it's been passed. This currently only applies to
2107 Windows. This option prevents any other sockets from binding to the
2108 host/port we've bound to, thus removing the possibility of the
2109 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2110 when a second SOCK_STREAM socket binds and accepts to a host/port
2111 that's already been bound by another socket. The optional preferred
2112 port parameter to bind_port() has been removed. Under no
2113 circumstances should tests be hard coding ports!
2114
2115 test_support.find_unused_port() has also been introduced, which will
2116 pass a temporary socket object to bind_port() in order to obtain an
2117 unused port. The temporary socket object is then closed and
2118 deleted, and the port is returned. This method should only be used
2119 for obtaining an unused port in order to pass to an external program
2120 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2121 a parameter to a server-oriented class that doesn't give you direct
2122 access to the underlying socket used.
2123
2124 Finally, test_support.HOST has been introduced, which should be used
2125 for the host argument of any relevant socket calls (i.e. bind and
2126 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002127
2128 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002129 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002130 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2131 test_asynchat and test_socket_ssl.
2132
Georg Brandl3ee81df2008-05-17 18:14:43 +00002133 It is now possible for multiple instances of the regression test

Fred Drakea8ee94b2008-03-01 02:45:07 +00002403- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002404 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002405
Georg Brandlad61bc82008-02-23 15:11:18 +00002406- Issue #2067: file.__exit__() now calls subclasses' close() method.
2407
2408- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002409
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002410- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002411 issue 215555 for a discussion.
2412
Eric Smitha73fbe72008-02-23 03:09:44 +00002413- Added the future_builtins module, which contains hex() and oct().
2414 These are the PEP 3127 version of these functions, designed to be
2415 compatible with the hex() and oct() builtins from Python 3.0. They
2416 differ slightly in their output formats from the existing, unchanged
2417 Python 2.6 builtins. The expected usage of the future_builtins
2418 module is:
2419 from future_builtins import hex, oct
2420
Eric Smith7ef40bf2008-02-20 23:34:22 +00002421- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2422 exponents for exponents with absolute value < 100. Follows C99
2423 standard. This is a change on Windows, which would use 3 digits.
2424 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2425 so that any alterations it does to the resulting string will be
2426 available in stringlib/formatter.h (for float.__format__).
2427
Eric Smith5a3c1352008-02-19 13:21:56 +00002428- Implemented PEP 3101, Advanced String Formatting. This adds a new
2429 builtin format(); a format() method for str and unicode; a
2430 __format__() method to object, str, unicode, int, long, float, and
2431 datetime; the class string.Formatter; and the C API
2432 PyObject_Format().
2433
Georg Brandl3ee81df2008-05-17 18:14:43 +00002434- Fixed several potential crashes, all caused by specially crafted
2435 __del__ methods exploiting objects in temporarily inconsistent
2436 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002437
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002438- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002439 prevent a possible crash: an Abstract Base Class would try to access
2440 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002441
Georg Brandl3ee81df2008-05-17 18:14:43 +00002442- Fixed repr() and str() of complex numbers with infinity or nan as
2443 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002444
Georg Brandl3ee81df2008-05-17 18:14:43 +00002445- Clear all free lists during a gc.collect() of the highest generation
2446 in order to allow pymalloc to free more arenas. Python may give back
2447 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002448
Georg Brandl3ee81df2008-05-17 18:14:43 +00002449- Issue #2045: Fix an infinite recursion triggered when printing a
2450 subclass of collections.defaultdict, if its default_factory is set
2451 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002452
Christian Heimesf75dbef2008-02-08 00:11:31 +00002453- Fixed a minor memory leak in dictobject.c. The content of the free
2454 list was not freed on interpreter shutdown.
2455
Georg Brandl3ee81df2008-05-17 18:14:43 +00002456- Limit free list of method and builtin function objects to 256
2457 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002458
Georg Brandl3ee81df2008-05-17 18:14:43 +00002459- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2460 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002461 to compact the internal free lists of pre-allocted ints and floats.
2462
Georg Brandl3ee81df2008-05-17 18:14:43 +00002463- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2464 calls. Python expected the return type int but the fork familie
2465 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002466
Georg Brandl3ee81df2008-05-17 18:14:43 +00002467- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2468 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002469
Georg Brandl3ee81df2008-05-17 18:14:43 +00002470- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2471 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002472
Georg Brandl3ee81df2008-05-17 18:14:43 +00002473- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2474 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002475
Georg Brandl3ee81df2008-05-17 18:14:43 +00002476- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2477 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002478
Georg Brandl3ee81df2008-05-17 18:14:43 +00002479- Patch #1473257: generator objects gain a gi_code attribute. This is
2480 the same object as the func_code attribute of the function that
2481 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002482
Georg Brandl3ee81df2008-05-17 18:14:43 +00002483- Issue #1920: "while 0" statements were completely removed by the
2484 compiler, even in the presence of an "else" clause, which is
2485 supposed to be run when the condition is false. Now the compiler
2486 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002487
Guido van Rossumeead05f2008-01-24 18:21:02 +00002488- A few crashers fixed: weakref_in_del.py (issue #1377858);
2489 loosing_dict_ref.py (issue #1303614, test67.py);
2490 borrowed_ref_[34].py (not in tracker).
2491
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002492- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002493 suppressed while an extension is loaded by calling SetErrorMode in
2494 dynload_win.c. The error is still reported properly.
2495
Georg Brandl3ee81df2008-05-17 18:14:43 +00002496- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002497 several extension methods and modules do not work without unicode
2498 support.
2499
Georg Brandl26543b12008-01-21 18:36:51 +00002500- Issue #1882: when compiling code from a string, encoding cookies in the
2501 second line of code were not always recognized correctly.
2502
Georg Brandl14404b62008-01-19 19:27:05 +00002503- Issue #1679: "0x" was taken as a valid integer literal.
2504
Georg Brandl6caad7d2008-01-26 14:19:22 +00002505- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002506 added.
2507
Christian Heimesc94e2b52008-01-14 04:13:37 +00002508- sys.float_info / PyFloat_GetInfo: The floating point information
2509 object was converted from a dict to a specialized structseq object.
2510
Georg Brandl3ee81df2008-05-17 18:14:43 +00002511- Patch #1816: Added sys.flags structseq. It exposes the status of
2512 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002513
Georg Brandl3ee81df2008-05-17 18:14:43 +00002514- Objects/structseq.c: Implemented new structseq representation. The
2515 patch makes structseqs (e.g. the return value of os.stat) more
2516 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002517
Georg Brandl3ee81df2008-05-17 18:14:43 +00002518- Patch #1700288: added a type attribute cache that caches method
2519 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002520
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002521- Bug #1776: __import__() no longer accepts filenames on any platform.
2522 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002523
Georg Brandlaed6c662008-01-07 17:25:53 +00002524- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2525
Georg Brandl3ee81df2008-05-17 18:14:43 +00002526- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2527 envvar and sys.dont_write_bytecode attribute. All these can be set
2528 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002529
Georg Brandl3ee81df2008-05-17 18:14:43 +00002530- Improve some exception messages when Windows fails to load an
2531 extension module. Now we get for example '%1 is not a valid Win32
2532 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002533
Georg Brandl3ee81df2008-05-17 18:14:43 +00002534- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00002535
Georg Brandl3ee81df2008-05-17 18:14:43 +00002536- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2537 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002538
Christian Heimes0a8143f2007-12-18 23:22:54 +00002539- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002540 and INF. float("nan"), float("inf") and float("-inf") now work on
2541 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002542
Georg Brandl3ee81df2008-05-17 18:14:43 +00002543- Compiler now generates simpler and faster code for dictionary
2544 literals. The oparg for BUILD_MAP now indicates an estimated
2545 dictionary size. There is a new opcode, STORE_MAP, for adding
2546 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002547
Georg Brandl3ee81df2008-05-17 18:14:43 +00002548- Issue #1638: %zd configure test fails on Linux.

2564 running, and if the deallocation of its frames somehow calls the
2565 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002566

2576 file can now be directly executed by passing their name to the
2577 interpreter. The directory/zipfile is automatically inserted as the
2578 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002579
Georg Brandl3ee81df2008-05-17 18:14:43 +00002580- Issue #1265: Fix a problem with sys.settrace, if the tracing
2581 function uses a generator expression when at the same time the
2582 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002583
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002584- sets and frozensets now have an isdisjoint() method.
2585
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002586- optimize the performance of builtin.sum().
2587
Neal Norwitz44f326e2007-10-05 05:29:17 +00002588- Fix warnings found by the new version of the Coverity checker.
2589
Georg Brandl3ee81df2008-05-17 18:14:43 +00002590- The enumerate() builtin function is no longer bounded to sequences
2591 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2592 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002593
Georg Brandl3ee81df2008-05-17 18:14:43 +00002594- Issue #1686386: Tuple's tp_repr did not take into account the
2595 possibility of having a self-referential tuple, which is possible
2596 from C code. Nor did object's tp_str consider that a type's tp_str
2597 could do something that could lead to an inifinite recursion.
2598 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2599 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002600
Georg Brandl3ee81df2008-05-17 18:14:43 +00002601- Issue #1164: It was possible to trigger deadlock when using the
2602 'print' statement to write to a file since the GIL was not released
2603 as needed. Now PyObject_Print() does the right thing along with
2604 various tp_print implementations of the built-in types and those in
2605 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002606
Georg Brandl3ee81df2008-05-17 18:14:43 +00002607- Issue #1147: Exceptions were directly allowing string exceptions in
2608 their throw() method even though string exceptions no longer
2609 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002610
Georg Brandl3ee81df2008-05-17 18:14:43 +00002611- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002614- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002615 PyObject_Call() never calling back out to Python code to trigger
2616 recursion depth updates/checks. Required the creation of a static
2617 RuntimeError instance in case normalizing an exception put the
2618 recursion check value past its limit. Fixes crashers
2619 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002620
Georg Brandl3ee81df2008-05-17 18:14:43 +00002621- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002634- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002635 __*__ attributes. (Some already existed, e.g., __doc__ and
2636 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002637
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002638- Add -3 option to the interpreter to warn about features that are
2639 deprecated and will be changed/removed in Python 3.0.
2640
Georg Brandl2134e752007-05-21 20:34:16 +00002641- Patch #1686487: you can now pass any mapping after '**' in function
2642 calls.
2643
Collin Winter62903052007-05-18 23:11:24 +00002644- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002645 "except E as target:". This is to provide forwards compatibility

Brett Cannon229cee22007-05-05 01:34:02 +00002648- Deprecate BaseException.message as per PEP 352.
2649
Georg Brandl3ee81df2008-05-17 18:14:43 +00002650- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002651 inherited from a builtin base.
2652
Vinay Sajip8549ce32007-05-06 17:53:37 +00002653- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002654 setting a plain string, ie don't expand to single letter identifiers.
2655
Raymond Hettinger13936692007-04-11 18:40:58 +00002656- Request #1191699: Slices can now be pickled.
2657
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002658- Request #1193128: str.translate() now allows a None argument for
2659 translations that only remove characters without re-mapping the
2660 remaining characters.
2661
Georg Brandl5cb76c12007-03-21 09:00:39 +00002662- Patch #1682205: a TypeError while unpacking an iterable is no longer
2663 masked by a generic one with the message "unpack non-sequence".
2664
Neal Norwitzaa754b72007-03-21 06:39:48 +00002665- Remove unused file Python/fmod.c.
2666
Guido van Rossum143b5642007-03-23 04:58:42 +00002667- Bug #1683368: The object.__init__() and object.__new__() methods are
2668 now stricter in rejecting excess arguments. The only time when
2669 either allows excess arguments is when it is not overridden and the
2670 other one is. For backwards compatibility, when both are
2671 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002672 warning later). Also, type.__init__() insists on the same signature
2673 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002674
Georg Brandl3ee81df2008-05-17 18:14:43 +00002675- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2676 object to complex using its __complex__() method before falling back
2677 to the __float__() method. Therefore, the functions in the cmath
2678 module now can operate on objects that define a __complex__()
2679 method.

2683 same slot names.

2696
Georg Brandl7b9c5552007-03-12 14:30:05 +00002697- Bug #1678647: write a newline after printing an exception in any
2698 case, even when converting the value to a string failed.
2699
Georg Brandl871f1bc2007-03-12 13:17:36 +00002700- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002701 its argument, if it exists. If not, it will work like before. This
2702 allows customizing the output of dir() in the presence of a
2703 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002704
Collin Winter276887b2007-03-12 16:11:39 +00002705- Patch #922167: Python no longer segfaults when faced with infinitely
2706 self-recursive reload() calls (as reported by bug #742342).
2707

2712 parthensized forms. This means complex(repr(x)) now works instead of
2713 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002714
Georg Brandlaa2321b2007-03-07 00:40:28 +00002715- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002716 makes the filenames the warning module prints much more sensible
2717 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002718

Georg Brandl0fca97a2007-03-05 22:28:08 +00002730- Patch #1674228: when assigning a slice (old-style), check for the
2731 sq_ass_slice instead of the sq_slice slot.
2732
Georg Brandl3ee81df2008-05-17 18:14:43 +00002733- When printing an unraisable error, don't print exceptions. before
2734 the name. This duplicates the behavior whening normally printing
2735 exceptions.

2744 created a weakref on itself during a __del__ call for new-style
2745 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00002785- Bug #1545497: when given an explicit base, int() did ignore NULs
2786 embedded in the string to convert.
2787
Georg Brandl846f73a2006-10-08 07:11:54 +00002788- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002836 generator expressions (x for x, in ... ) works again. Fixing this
2837 problem required changing the .pyc magic number. This means that
2838 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003641- The implementation of UnicodeError objects has been simplified
3642 (start and end attributes are now stored directly as Py_ssize_t
3643 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003645- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3646 with RFC 3207 and forgets any knowledge obtained from the server not
3647 obtained from the TLS negotiation itself. Patch contributed by Bill
3648 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003649
Georg Brandl3ee81df2008-05-17 18:14:43 +00003650- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003651 that the SMTP.starttls() caller no longer needs to call ehlo()
3652 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003653 does not claim to support starttls. Adds the
3654 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3655 Fenner.

3735 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3736 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003753 time so that opening a database previously created with the DB_DUP
3754 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3755 opens. Specifically: dictionary assignment to a DB object will
3756 replace all values for a given key when the database allows
3757 duplicate values. DB users should use DB.put(k, v) when they want
3758 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003759

3765 characters with ASCII value less than 32. Also, it correctly quotes
3766 dots only if they occur on a single line, as opposed to the previous
3767 behavior of quoting dots if they are the second character of any
3768 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003769

Georg Brandl3ee81df2008-05-17 18:14:43 +00004174- Removed the macfs module. It had been deprecated since Python 2.5.
4175 This lead to the deprecation of macostools.touched() as it relied
4176 solely on macfs and was a no-op under OS X.
