152 rejected; (2) parsing of strings representing infinities and nans
153 was locale aware; and (3) the interpretation of fromhex('-nan')
154 didn't match that of float('-nan').
155
Eric Smitha985a3a2009-05-05 18:26:08 +0000156- Issue #5920: For float.__format__, change the behavior with the
157 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
158 to be like 'g' but with at least one decimal point and with a
159 default precision of 12. Previously, the behavior the same but with
160 a default precision of 6. This more closely matches str(), and
161 reduces surprises when adding alignment flags to the empty
162 presentation type. This also affects the new complex.__format__ in
163 the same way.
164
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000165- Issue #5890: in subclasses of 'property' the __doc__ attribute was

174
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000175- Issue #5864: Fix empty format code formatting for floats so that it

Mark Dickinson95bc9802009-04-24 12:46:53 +0000189- Issue #5816: complex(repr(z)) now recovers z exactly, even when
190 z involves nans, infs or negative zeros.
191
Eric Smithaca19e62009-04-22 13:29:05 +0000192- Implement PEP 378, Format Specifier for Thousands Separator, for
193 floats, ints, and longs.
194
195- Issue #5515: 'n' formatting for ints, longs, and floats handles
196 leading zero formatting poorly.
197
198- Issue #5772: For float.__format__, don't add a trailing ".0" if
199 we're using no type code and we have an exponent.

206
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000207- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000208 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000209
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000210- Issue #5759: float() didn't call __float__ on str subclasses.

228 untrackable objects are not tracked by the garbage collector. This can
229 reduce the size of collections and therefore the garbage collection overhead
230 on long-running programs, depending on their particular use of datatypes.
231
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000232- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

237 2**15 for the internal representation of integers, for performance
238 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
239 --enable-big-digits option to configure, which overrides the
240 default. Add sys.long_info structseq to provide information about
241 the internal format.

252
Brett Cannon6c4cff02009-03-11 04:51:06 +0000253- Issue #3652: Make the 'line' argument for warnings.showwarning() a
254 requirement. Means the DeprecationWarning from Python 2.6 can go away.

265 on a 64-bit system.
266
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000267- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

274
Georg Brandl29c6a282009-04-05 20:23:13 +0000275- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000276 were suppressing all exceptions. These include list(), filter(), map(),

305
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000306- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
307 an existing .py counterpart, override the co_filename attributes of all
308 code objects if the original filename is obsolete (which can happen if the
309 file has been renamed, moved, or if it is accessed through different paths).
310 Patch by Ziga Seilnacht and Jean-Paul Calderone.
311
Martin v. Löwis5344c992009-01-02 20:32:55 +0000312- Issue #4075: Use OutputDebugStringW in Py_FatalError.
313
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000314- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
315 file with `str' filename on Windows.
316
Antoine Pitrouaa687902009-01-01 14:11:22 +0000317- Issue #3680: Reference cycles created through a dict, set or deque iterator
318 did not get collected.
319
Nick Coghlan180e4002008-12-30 01:18:48 +0000320- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
321 where the tp_hash and tp_dict slots are both NULL.
322
Benjamin Peterson7af65562008-12-29 17:56:58 +0000323- Issue #4764: With io.open, IOError.filename is set when trying to open a
324 directory on POSIX systems.
325
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000326- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
327 systems.
328
Georg Brandl6425a2f2008-12-28 11:54:53 +0000329- Issue #4759: None is now allowed as the first argument of
330 bytearray.translate(). It was always allowed for bytes.translate().
331
Skip Montanarof205c132008-12-23 03:30:15 +0000332- Added test case to ensure attempts to read from a file opened for writing
333 fail.
334
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000335- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
336 print elapsed times, not only when some objects are uncollectable /
337 unreachable. Original patch by Neil Schemenauer.
338

345 context manager returns a value that cannot be converted to a bool.
346
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000347- Issue #4597: Fixed several opcodes that weren't always propagating
348 exceptions.
349
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000350- Issue #4445: Replace "sizeof(PyStringObject)" with
351 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
352 str instances. On a typical machine this saves 3 bytes of memory
353 (on average) per string allocation.
354
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000355- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
356 interpreter to abort ("Fatal Python error: Could not reset the stack!")
357 instead of throwing a MemoryError.
358
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000359- Issue #3689: The list reversed iterator now supports __length_hint__
360 instead of __len__. Behavior now matches other reversed iterators.
361
Benjamin Petersonc078f922008-11-21 22:27:24 +0000362- Issue #4367: Python would segfault during compiling when the unicodedata
363 module couldn't be imported and \N escapes were present.
364
Vinay Sajip213faca2008-12-03 23:22:58 +0000365- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000366 method on file objects with closefd=False. The file descriptor is still
367 kept open but the file object behaves like a closed file. The ``FileIO``
368 object also got a new readonly attribute ``closefd``.
369
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000370- Issue #4348: Some bytearray methods returned that didn't cause any change to
371 the bytearray, returned the same bytearray instead of a copy.
372
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000373- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

378
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000379- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
380 exec statement.
381
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000382- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
383 method does not return iterators for the 4th and 5th items.
384
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000385- Issue #4209: Enabling unicode_literals and the print_function in the same
386 __future__ import didn't work.
387
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000388- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000389 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000390
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000391- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
392 returned a path longer than MAX_PATH. (But It's doubtful this code path is
393 really executed because I cannot move to such directory on win2k)
394
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000395- Issue #4069: When set.remove(element) is used with a set element, the element
396 is temporarily replaced with an equivalent frozenset. But the eventual
397 KeyError would always report the empty frozenset([]) as the missing key. Now
398 it correctly refers to the initial element.
399
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000400- Issue #4509: Various issues surrounding resize of bytearray objects to
401 which there are buffer exports.
402

410 short file names.
411
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000412- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
413 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000414
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000415- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
416 returned them on 64bit platforms.
417
Walter Dörwalded960ac2009-05-03 22:36:33 +0000418- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
419 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
420 step. This avoids problems with counting UTF-8 bytes that ignores the effect
421 of using the replace error handler in PyUnicode_DecodeUTF8().
422
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000423- Issue #3739: The unicode-internal encoder now reports the number of characters
424 consumed like any other encoder (instead of the number of bytes).

430 a modification is done through it. This fixes inconsistencies and test
431 failures on systems with slightly bogus mtime behaviour.
432
Gregory P. Smith38f5d8f2009-11-01 18:33:55 +0000433- Issue #7246 & Issue #7208: getpass now properly flushes input before
434 reading from stdin so that existing input does not confuse it and
435 lead to incorrect entry or an IOError. It also properly flushes it
436 afterwards to avoid the terminal echoing the input afterwards on
437 OSes such as Solaris.
438
Mark Dickinson6f390012009-10-29 12:11:18 +0000439- Issue #7233: Fix a number of two-argument Decimal methods to make

1549 leak-chasing test runs give sensible results. The previous method of
1550 reaping threads could return successfully while some Thread objects were
1551 still referenced. This also introduces a new private function:

1570 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1571 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1572 skip the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00001574- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running

1578 it easy to import both normal and optimised versions of modules.
1579 test_heapq and test_warnings have been adjusted to use it, tests for
1580 other modules with both C and Python implementations in the stdlib
1581 can be adjusted to use it over time.

1588
R. David Murray41448c52009-03-31 19:57:24 +00001589- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001590 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001591 from test support, which does the conversion.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001689- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1690 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1691 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1692 ``printf`` function, whereas PyString_FromFormat has an independent
1693 implementation and uses "%zd" on all platforms for size_t values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001697- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1698 error.
1699
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001700- Issue #3777: long() applied to a float object now always return a long
1701 object; previously an int would be returned for small values. the __long__
1702 method is allowed to return either an int or a long, but the behaviour of
1703 float objects should not change to respect backward compatibility.
1704
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001705- Issue #3751: str.rpartition would perform a left-partition when called with
1706 a unicode argument.
1707
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001708- Issue #3683: Fix compilation when --without-threads is given.
1709
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001710- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001711 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001712 was correctly parsed but parsing of subsequent arguments failed.
1713
Vinay Sajip35e3b032008-09-01 14:33:59 +00001714- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001715 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1716 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1717 when given a tuple of classes as second argument, were looking up
1718 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1719 type object.
1720
Neal Norwitz18aa3882008-08-24 05:04:52 +00001721- Fix crashes on memory allocation failure found with failmalloc.

1790 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1791 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001858What's New in Python 2.6 beta 3?
1859================================
1860
Barry Warsaw07a4a382008-08-21 01:15:08 +00001861*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001862
1863Core and Builtins
1864-----------------
1865
Guido van Rossumf8402962008-08-20 15:01:50 +00001866- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1867 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1868 extensions do not automatically benefit from the class attribute
1869 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1870 to their tp_flags field if they care. This is a backwards
1871 compatibility feature; in 3.0, all types will use the cache by
1872 default.
1873
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001874- Keyword arguments can now follow starred arguments. (``f(a, *args,
1875 keyword=23)`` is now valid syntax.)
1876
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001877- ctypes function pointers that are COM methods have a boolean True
1878 value again.
1879
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001880- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1881 by denying s# to parse objects that have a releasebuffer procedure,
1882 and introducing s*.
1883
Georg Brandl1e13ea92008-08-11 09:07:59 +00001884- Issue #3537: Fix an assertion failure when an empty but presized dict
1885 object was stored in the freelist.
1886
Mark Dickinsonb6467572008-08-04 21:30:09 +00001887- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1888 ValueError consistently across platforms.
1889
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001890- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1891 (64bit Unix, for example), unichr() would truncate its argument and return
1892 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1893
Neal Norwitze7d8be82008-07-31 17:17:14 +00001894- Apply security patches from Apple.
1895
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001896- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1897 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1898
Antoine Pitrou92f82162008-07-25 22:22:08 +00001899- Issue #1819: function calls with several named parameters are now on
1900 average 35% faster (as measured by pybench).
1901
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001902- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1903 the python debugger steps into a class statement: the free variables (local
1904 variables defined in an outer scope) would be deleted from the outer scope.
1905
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001906- Issue #2620: Overflow checking when allocating or reallocating memory
1907 was not always being done properly in some python types and extension
1908 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1909 all been updated to perform better checks and places in the code that
1910 would previously leak memory on the error path when such an allocation
1911 failed have been fixed.

1915
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001916- Issue #3612: Added some missing basic types in ctypes.wintypes.
1917
Benjamin Petersone977ad42008-08-20 01:42:01 +00001918- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1919 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1920
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001921- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1922 version reported by these tools does not necessarily follow the python
1923 version numbering scheme, so the module is less strict when parsing it.
1924
Nick Coghlanf70385a2008-08-18 12:42:46 +00001925- Issue #2235: Added Py3k warnings for types which will become unhashable
1926 under the stricter __hash__ inheritance rules in 3.0. Several types
1927 which did not meet the rules for hash invariants and were already
1928 unhashable in 3.0 have now been explicitly flagged as unhashable in
1929 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1930 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1931
Brett Cannon88f801d2008-08-18 00:46:22 +00001932- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1933 imported into the module but exposed as part of the module's API.
1934
Brett Cannon7b96f072008-08-18 00:41:11 +00001935- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1936
Brett Cannon46225e72008-08-18 00:36:52 +00001937- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001939- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1940
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001941- Issue #3575: Incremental decoder's decode function now takes bytearray
1942 by using 's*' instead of 't#'.
1943
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001944- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001945 fails unicode conversion on 2nd parameter. (windows only)
1946
Facundo Batista94f243a2008-08-17 03:38:39 +00001947- Issue 2464. urllib2 now supports a malformation in the URL received
1948 in a redirect.
1949
Brett Cannonabe423e2008-08-16 21:47:07 +00001950- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001951 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001952
Facundo Batistaeb90b782008-08-16 14:44:07 +00001953- Issue #2776: fixed small issue when handling an URL with double slash
1954 after a 302 response in the case of not going through a proxy.
1955
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001956- Issue #2676: in the email package, content-type parsing was hanging on
1957 pathological input because of quadratic or exponential behaviour of a
1958 regular expression.
1959
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001960- Issue #3476: binary buffered reading through the new "io" library is now
1961 thread-safe.
1962
Brett Cannonbf3157b2008-08-14 05:00:03 +00001963- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1964 since mimetools itself is deprecated. Because modules are cached, all
1965 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1966
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001967- Issue #3134: shutil referenced undefined WindowsError symbol.
1968
Robert Schuppenies14646332008-08-10 11:01:53 +00001969- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1970 menu entries were not deleted.
1971
Brett Cannon83e81842008-08-09 23:30:55 +00001972- Copied the implementation of reduce() to _functools.reduce() to have a
1973 version that did not raise a DeprecationWarning under -3.
1974
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001975- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1976 a MemoryError rather than silently stop the iteration.
1977
Guido van Rossum59ce9012008-08-09 14:55:34 +00001978- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1979 to _sre.compile() will now be rejected. This should not affect anybody
1980 since the re.compile() function never generates invalid re-bytecode.
1981
Skip Montanaroa032bf42008-08-08 22:52:51 +00001982- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1983 upon first access it can be automatically initialized from the csv file if
1984 it wasn't initialized during instantiation.

Antoine Pitroude781a42008-08-09 12:43:23 +00002001 asking for a specific length. This problem only affected files opened

2058-----------------
2059
Georg Brandl3e483f62008-07-16 22:57:41 +00002060- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2061 its methods now allow for items objects that can be converted to
2062 an integer using operator.index().
2063
Mark Dickinson64b7e502008-07-16 09:40:03 +00002064- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2065 produced a ValueError instead of giving the correct float.
2066
Eric Smitha5fa5a22008-07-16 00:11:49 +00002067- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2068 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2069
Mark Dickinson7103aa42008-07-15 19:08:33 +00002070- Issue #3008: the float type has a new instance method 'float.hex'
2071 and a new class method 'float.fromhex' to convert floating-point
2072 numbers to and from hexadecimal strings, respectively.
2073
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002074- Issue #2235: __hash__ is once again inherited by default. To allow
2075 collections.Hashable to remain meaningful in the presence of the
2076 default hash implementation (object.__hash__), it is now possible
2077 to explicit block inheritance of hash by setting __hash__=None at
2078 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2079 level.
2080
Nick Coghlanb028f502008-07-13 14:52:36 +00002081- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2082 the parent module cannot be found while performing an absolute import.
2083 This means that an incorrectly defined __package__ attribute will
2084 now only prevent relative imports in that module rather than causing
2085 all imports from that module to fail.
2086
Nick Coghlan14ff9942008-07-08 14:21:42 +00002087- Issue #2517: Allow unicode messages in Exceptions again by correctly

2097 another thread's dictionary.
2098
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002099- Issue #3004: Minor change to slice.indices(): the start and stop
2100 arguments are now treated identically, making the behaviour easier
2101 to describe and understand. For example, slice(None, -10,
2102 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2103 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2104 10, -1).
2105
Georg Brandl278fc502008-07-19 12:46:12 +00002106- Issue #3219: Calling a function with repeated keyword arguments,
2107 f(a=2, a=23), would not cause a syntax error. This was a regression
2108 from 2.4 caused by the switch to the new compiler.

2119 error when they failed.
2120
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002121- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002146- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2147 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002148 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002149 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002165- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2553
Brett Cannonb61d8012008-05-11 23:39:04 +00002554- ``Lib/lib-old`` is now added to sys.path.
2555
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002556- On MacOS X it is now possible to install the framework in 64-bit
2557 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002558 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002559
2560 This is controlled by the configure argument ``--with-universal-archs``:
2561
2562 - ``--with-universal-archs=all``: install 4-way universal
2563
2564 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2565
2566 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2567
2568 This option should be used in combination with ``--enable-universalsdk=``.
2569
2570 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2575
Georg Brandl74a1dea2008-05-28 11:21:39 +00002576- Add ``PyType_Modified()`` as a public API to clear the type cache.
2577
2578- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002579
2580- The PyString functions have been renamed to PyBytes. A batch of
2581 defines were added so that the linker still sees the original
2582 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002620- Issue #1631171: Re-implement the 'warnings' module in C (the
2621 original Python code has been kept as backup). This will allow for
2622 using the 'warning's machinery in such places as the parser where
2623 use of pure Python code is not possible. Both the ``showarning()``
2624 and ``formatwarning()`` gain an optional 'line' argument which is
2625 not called by default for backwards-compatibility reasons. Setting
2626 ``warnings.showwarning()`` to an implementation that lacks support
2627 for the ``line`` argument will raise a DeprecationWarning.

2651
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002652- The getpass module has been improved on Unix. It now uses /dev/tty
2653 by default and uses stderr instead of stdout. A GetPassWarning is
2654 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002669- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002670 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002690- Issue #2550: The approach used by client/server code for obtaining
2691 ports to listen on in network-oriented tests has been refined in an
2692 effort to facilitate running multiple instances of the entire
2693 regression test suite in parallel without issue.
2694 test_support.bind_port() has been fixed such that it will always
2695 return a unique port -- which wasn't always the case with the
2696 previous implementation, especially if socket options had been set
2697 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2698 new implementation of bind_port() will actually raise an exception
2699 if it is passed an AF_INET/SOCK_STREAM socket with either the
2700 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2701 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2702 the socket it's been passed. This currently only applies to
2703 Windows. This option prevents any other sockets from binding to the
2704 host/port we've bound to, thus removing the possibility of the
2705 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2706 when a second SOCK_STREAM socket binds and accepts to a host/port
2707 that's already been bound by another socket. The optional preferred
2708 port parameter to bind_port() has been removed. Under no
2709 circumstances should tests be hard coding ports!
2710
2711 test_support.find_unused_port() has also been introduced, which will
2712 pass a temporary socket object to bind_port() in order to obtain an
2713 unused port. The temporary socket object is then closed and
2714 deleted, and the port is returned. This method should only be used
2715 for obtaining an unused port in order to pass to an external program
2716 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2717 a parameter to a server-oriented class that doesn't give you direct
2718 access to the underlying socket used.
2719
2720 Finally, test_support.HOST has been introduced, which should be used
2721 for the host argument of any relevant socket calls (i.e. bind and
2722 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002723
2724 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002725 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002726 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2727 test_asynchat and test_socket_ssl.
2728
Georg Brandl3ee81df2008-05-17 18:14:43 +00002729 It is now possible for multiple instances of the regression test
2730 suite to run in parallel without issue.

2998
Fred Drakea8ee94b2008-03-01 02:45:07 +00002999- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003000 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003006- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003007 issue 215555 for a discussion.
3008
Eric Smitha73fbe72008-02-23 03:09:44 +00003009- Added the future_builtins module, which contains hex() and oct().
3010 These are the PEP 3127 version of these functions, designed to be
3011 compatible with the hex() and oct() builtins from Python 3.0. They
3012 differ slightly in their output formats from the existing, unchanged
3013 Python 2.6 builtins. The expected usage of the future_builtins
3014 module is:
3015 from future_builtins import hex, oct
3016
Eric Smith7ef40bf2008-02-20 23:34:22 +00003017- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3018 exponents for exponents with absolute value < 100. Follows C99
3019 standard. This is a change on Windows, which would use 3 digits.
3020 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3021 so that any alterations it does to the resulting string will be
3022 available in stringlib/formatter.h (for float.__format__).
3023
Eric Smith5a3c1352008-02-19 13:21:56 +00003024- Implemented PEP 3101, Advanced String Formatting. This adds a new
3025 builtin format(); a format() method for str and unicode; a
3026 __format__() method to object, str, unicode, int, long, float, and
3027 datetime; the class string.Formatter; and the C API
3028 PyObject_Format().
3029
Georg Brandl3ee81df2008-05-17 18:14:43 +00003030- Fixed several potential crashes, all caused by specially crafted
3031 __del__ methods exploiting objects in temporarily inconsistent
3032 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003034- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003035 prevent a possible crash: an Abstract Base Class would try to access
3036 a slot on a registered virtual subclass.

3042 in order to allow pymalloc to free more arenas. Python may give back
3043 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003044
Georg Brandl3ee81df2008-05-17 18:14:43 +00003045- Issue #2045: Fix an infinite recursion triggered when printing a
3046 subclass of collections.defaultdict, if its default_factory is set
3047 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003048
Christian Heimesf75dbef2008-02-08 00:11:31 +00003049- Fixed a minor memory leak in dictobject.c. The content of the free
3050 list was not freed on interpreter shutdown.
3051
Georg Brandl3ee81df2008-05-17 18:14:43 +00003052- Limit free list of method and builtin function objects to 256

3056 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003057 to compact the internal free lists of pre-allocted ints and floats.
3058
Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3060 calls. Python expected the return type int but the fork familie
3061 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003062

Christian Heimes4d4f2702008-01-30 11:32:37 +00003071
Georg Brandl3ee81df2008-05-17 18:14:43 +00003072- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3073 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003074
Georg Brandl3ee81df2008-05-17 18:14:43 +00003075- Patch #1473257: generator objects gain a gi_code attribute. This is
3076 the same object as the func_code attribute of the function that
3077 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003078
Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Issue #1920: "while 0" statements were completely removed by the
3080 compiler, even in the presence of an "else" clause, which is
3081 supposed to be run when the condition is false. Now the compiler
3082 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003083
Guido van Rossumeead05f2008-01-24 18:21:02 +00003084- A few crashers fixed: weakref_in_del.py (issue #1377858);
3085 loosing_dict_ref.py (issue #1303614, test67.py);
3086 borrowed_ref_[34].py (not in tracker).
3087
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003088- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003089 suppressed while an extension is loaded by calling SetErrorMode in
3090 dynload_win.c. The error is still reported properly.
3091
Georg Brandl3ee81df2008-05-17 18:14:43 +00003092- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003093 several extension methods and modules do not work without unicode
3094 support.
3095
Georg Brandl26543b12008-01-21 18:36:51 +00003096- Issue #1882: when compiling code from a string, encoding cookies in the
3097 second line of code were not always recognized correctly.
3098
Georg Brandl14404b62008-01-19 19:27:05 +00003099- Issue #1679: "0x" was taken as a valid integer literal.
3100
Georg Brandl6caad7d2008-01-26 14:19:22 +00003101- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003102 added.
3103
Christian Heimesc94e2b52008-01-14 04:13:37 +00003104- sys.float_info / PyFloat_GetInfo: The floating point information
3105 object was converted from a dict to a specialized structseq object.
3106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Patch #1816: Added sys.flags structseq. It exposes the status of
3108 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Objects/structseq.c: Implemented new structseq representation. The
3111 patch makes structseqs (e.g. the return value of os.stat) more
3112 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003113
Georg Brandl3ee81df2008-05-17 18:14:43 +00003114- Patch #1700288: added a type attribute cache that caches method
3115 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003116
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003117- Bug #1776: __import__() no longer accepts filenames on any platform.
3118 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003119
Georg Brandlaed6c662008-01-07 17:25:53 +00003120- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3121
Georg Brandl3ee81df2008-05-17 18:14:43 +00003122- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3123 envvar and sys.dont_write_bytecode attribute. All these can be set
3124 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003125
Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Improve some exception messages when Windows fails to load an
3127 extension module. Now we get for example '%1 is not a valid Win32
3128 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003129
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00003131
Georg Brandl3ee81df2008-05-17 18:14:43 +00003132- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3133 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003134
Christian Heimes0a8143f2007-12-18 23:22:54 +00003135- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136 and INF. float("nan"), float("inf") and float("-inf") now work on
3137 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003138
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Compiler now generates simpler and faster code for dictionary
3140 literals. The oparg for BUILD_MAP now indicates an estimated
3141 dictionary size. There is a new opcode, STORE_MAP, for adding
3142 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003143
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00003145
Georg Brandl3ee81df2008-05-17 18:14:43 +00003146- Issue #1620: New property decorator syntax was modifying the
3147 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003148
Georg Brandl3ee81df2008-05-17 18:14:43 +00003149- Issue #1538: Avoid copying string in split/rsplit if the split char
3150 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003151
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003152- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003153 SystemError.
3154
Nick Coghlanef01d822007-12-03 12:55:17 +00003155- PEP 366: Allow explicit relative imports when executing modules

3160 running, and if the deallocation of its frames somehow calls the
3161 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003162

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003166 attribute of an empty cell object.
3167
Georg Brandl3ee81df2008-05-17 18:14:43 +00003168- Issue #1460: The utf-7 incremental decoder did not accept truncated
3169 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003170
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171- Patch #1739468: Directories and zipfiles containing a __main__.py
3172 file can now be directly executed by passing their name to the
3173 interpreter. The directory/zipfile is automatically inserted as the
3174 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003175
Georg Brandl3ee81df2008-05-17 18:14:43 +00003176- Issue #1265: Fix a problem with sys.settrace, if the tracing
3177 function uses a generator expression when at the same time the
3178 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003179
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003180- sets and frozensets now have an isdisjoint() method.
3181
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003182- optimize the performance of builtin.sum().
3183
Neal Norwitz44f326e2007-10-05 05:29:17 +00003184- Fix warnings found by the new version of the Coverity checker.
3185
Georg Brandl3ee81df2008-05-17 18:14:43 +00003186- The enumerate() builtin function is no longer bounded to sequences
3187 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3188 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003189
Georg Brandl3ee81df2008-05-17 18:14:43 +00003190- Issue #1686386: Tuple's tp_repr did not take into account the
3191 possibility of having a self-referential tuple, which is possible
3192 from C code. Nor did object's tp_str consider that a type's tp_str
3193 could do something that could lead to an inifinite recursion.
3194 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3195 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003196
Georg Brandl3ee81df2008-05-17 18:14:43 +00003197- Issue #1164: It was possible to trigger deadlock when using the
3198 'print' statement to write to a file since the GIL was not released
3199 as needed. Now PyObject_Print() does the right thing along with
3200 various tp_print implementations of the built-in types and those in
3201 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003202
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203- Issue #1147: Exceptions were directly allowing string exceptions in
3204 their throw() method even though string exceptions no longer
3205 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003206
Georg Brandl3ee81df2008-05-17 18:14:43 +00003207- Issue #1096: Prevent a segfault from getting the repr of a very
3208 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003209
Brett Cannon1e534b52007-09-07 04:18:30 +00003210- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003211 PyObject_Call() never calling back out to Python code to trigger
3212 recursion depth updates/checks. Required the creation of a static
3213 RuntimeError instance in case normalizing an exception put the
3214 recursion check value past its limit. Fixes crashers
3215 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003216
Georg Brandl3ee81df2008-05-17 18:14:43 +00003217- Patch #1031213: Decode source line in SyntaxErrors back to its
3218 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +00003219
Georg Brandl7c3b50d2007-07-12 08:38:00 +00003220- Patch #1673759: add a missing overflow check when formatting floats
3221 with %G.
3222
Georg Brandl3ee81df2008-05-17 18:14:43 +00003223- Prevent expandtabs() on string and unicode objects from causing a
3224 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00003225

Georg Brandla5ea6892007-06-01 11:33:33 +00003229
Neal Norwitz0ac60192007-05-27 04:08:54 +00003230- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003231 __*__ attributes. (Some already existed, e.g., __doc__ and
3232 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003233
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003234- Add -3 option to the interpreter to warn about features that are
3235 deprecated and will be changed/removed in Python 3.0.
3236
Georg Brandl2134e752007-05-21 20:34:16 +00003237- Patch #1686487: you can now pass any mapping after '**' in function
3238 calls.
3239
Collin Winter62903052007-05-18 23:11:24 +00003240- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003241 "except E as target:". This is to provide forwards compatibility
3242 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003243
Brett Cannon229cee22007-05-05 01:34:02 +00003244- Deprecate BaseException.message as per PEP 352.
3245
Georg Brandl3ee81df2008-05-17 18:14:43 +00003246- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003247 inherited from a builtin base.
3248
Vinay Sajip8549ce32007-05-06 17:53:37 +00003249- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003250 setting a plain string, ie don't expand to single letter identifiers.
3251
Raymond Hettinger13936692007-04-11 18:40:58 +00003252- Request #1191699: Slices can now be pickled.
3253
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003254- Request #1193128: str.translate() now allows a None argument for
3255 translations that only remove characters without re-mapping the
3256 remaining characters.
3257
Georg Brandl5cb76c12007-03-21 09:00:39 +00003258- Patch #1682205: a TypeError while unpacking an iterable is no longer
3259 masked by a generic one with the message "unpack non-sequence".
3260
Neal Norwitzaa754b72007-03-21 06:39:48 +00003261- Remove unused file Python/fmod.c.
3262
Guido van Rossum143b5642007-03-23 04:58:42 +00003263- Bug #1683368: The object.__init__() and object.__new__() methods are
3264 now stricter in rejecting excess arguments. The only time when
3265 either allows excess arguments is when it is not overridden and the
3266 other one is. For backwards compatibility, when both are
3267 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003268 warning later). Also, type.__init__() insists on the same signature
3269 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003270
Georg Brandl3ee81df2008-05-17 18:14:43 +00003271- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3272 object to complex using its __complex__() method before falling back
3273 to the __float__() method. Therefore, the functions in the cmath
3274 module now can operate on objects that define a __complex__()
3275 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003276
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277- Patch #1623563: allow __class__ assignment for classes with
3278 __slots__. The old and the new class are still required to have the
3279 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003280
Georg Brandl3ee81df2008-05-17 18:14:43 +00003281- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Patch #1462488: Python no longer segfaults when
3285 ``object.__reduce_ex__()`` is called with an object that is faking
3286 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003287
Georg Brandl3ee81df2008-05-17 18:14:43 +00003288- Patch #1680015: Don't modify __slots__ tuple if it contains an
3289 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00003291- Patch #1444529: the builtin compile() now accepts keyword arguments.
3292
Georg Brandl7b9c5552007-03-12 14:30:05 +00003293- Bug #1678647: write a newline after printing an exception in any
3294 case, even when converting the value to a string failed.
3295
Georg Brandl871f1bc2007-03-12 13:17:36 +00003296- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003297 its argument, if it exists. If not, it will work like before. This
3298 allows customizing the output of dir() in the presence of a
3299 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003300
Collin Winter276887b2007-03-12 16:11:39 +00003301- Patch #922167: Python no longer segfaults when faced with infinitely
3302 self-recursive reload() calls (as reported by bug #742342).
3303
Georg Brandl3ee81df2008-05-17 18:14:43 +00003304- Patch #1675981: remove unreachable code from ``type.__new__()``
3305 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003307- Patch #1491866: change the complex() constructor to allow
3308 parthensized forms. This means complex(repr(x)) now works instead of
3309 raising a ValueError.

3820 ".cpp" too.
3821
Facundo Batistad918a652007-04-24 13:54:38 +00003822- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003823 the client's request was successfully received, understood, and
3824 accepted. Now in these cases no error is raised in urllib (issue
3825 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003826

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003833- Added a timeout parameter to the constructor of other protocols
3834 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3835 work started with create_connection() and timeout in httplib, and
3836 closes patch #723312.
3837
Vinay Sajip8549ce32007-05-06 17:53:37 +00003838- Patch #1676823: Added create_connection() to socket.py, which may be
3839 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003840 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003841
Martin v. Löwis0af33882007-03-23 13:27:15 +00003842- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003849- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
3850 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00003851 directories.
3852

3854 GNOME or KDE browser, depending on whether there is a session of one
3855 of those present. Also, it tries the Windows default browser before
3856 trying Mozilla variants.

3862
Georg Brandlf66b6032007-03-14 08:27:52 +00003863- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003864 AttributeError instead of an IOError when the server's response
3865 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003866
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867- Patch #957650: "%var%" environment variable references are now
3868 properly expanded in ntpath.expandvars(), also "~user" home
3869 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00003870
Georg Brandl3ee81df2008-05-17 18:14:43 +00003871- Patch #1429539: pdb now correctly initializes the __main__ module
3872 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003873 correctly now.
3874
Georg Brandlbad6f192007-03-13 21:32:56 +00003875- The nonobvious commands.getstatus() function is now deprecated.

3881
Georg Brandl3ee81df2008-05-17 18:14:43 +00003882- Patch #1530482: add pydoc.render_doc() which returns the
3883 documentation for a thing instead of paging it to stdout, which
3884 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003885
Georg Brandl3ee81df2008-05-17 18:14:43 +00003886- Patch #1533909: the timeit module now accepts callables in addition

3892 parameter which can be set to False to prevent the default
3893 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003894
Georg Brandl9e6b4702007-03-13 18:15:41 +00003895- Patch #1581073: add a flag to textwrap that prevents the dropping of
3896 whitespace while wrapping.
3897
Georg Brandl92a6bae2007-03-13 17:43:32 +00003898- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003899 are set for invalid interpolation sequences that would lead to
3900 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003901

3914
Georg Brandl94fe3f52007-03-13 09:32:11 +00003915- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003916 field names in its exception message if you try to write a record
3917 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003935

3943 returned string up to the first NUL character.
3944

3954
Georg Brandl3ee81df2008-05-17 18:14:43 +00003955- unittest now verifies more of its assumptions. In particular,
3956 TestCase and TestSuite subclasses (not instances) are no longer
3957 accepted in TestSuite.addTest(). This should cause no
3958 incompatibility since it never made sense with ordinary subclasses
3959 -- the failure just occurred later, with a more cumbersome
3960 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003961

3969 given a unicode argument and os.listdir() returns unicode filenames.
3970
Georg Brandl3ee81df2008-05-17 18:14:43 +00003971- Patch #1673619: setup.py identifies extension modules it doesn't

3973 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004349 time so that opening a database previously created with the DB_DUP
4350 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4351 opens. Specifically: dictionary assignment to a DB object will
4352 replace all values for a given key when the database allows
4353 duplicate values. DB users should use DB.put(k, v) when they want
4354 to store duplicates; not DB[k] = v.

4361 characters with ASCII value less than 32. Also, it correctly quotes
4362 dots only if they occur on a single line, as opposed to the previous
4363 behavior of quoting dots if they are the second character of any
4364 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004365
