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
Mark Dickinson1a707982008-12-17 16:14:37 +0000339- Issue #3439: Add a bit_length method to int and long.

343
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000344- Issue #4597: Fixed exception handling when the __exit__ function of a
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.
374
Benjamin Peterson273c2332008-11-17 22:39:09 +0000375- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
376
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000377- Issue #4048: The parser module now correctly validates relative imports.
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
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000403- Issue #4748: Lambda generators no longer return a value.

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).

437 failures on systems with slightly bogus mtime behaviour.
438
Gregory P. Smith38f5d8f2009-11-01 18:33:55 +0000439- Issue #7246 & Issue #7208: getpass now properly flushes input before
440 reading from stdin so that existing input does not confuse it and
441 lead to incorrect entry or an IOError. It also properly flushes it
442 afterwards to avoid the terminal echoing the input afterwards on
443 OSes such as Solaris.
444
Mark Dickinson6f390012009-10-29 12:11:18 +0000445- Issue #7233: Fix a number of two-argument Decimal methods to make

1558 leak-chasing test runs give sensible results. The previous method of
1559 reaping threads could return successfully while some Thread objects were
1560 still referenced. This also introduces a new private function:

1579 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1580 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1581 skip the tests if DISPLAY is defined but can't be used.

1587 it easy to import both normal and optimised versions of modules.
1588 test_heapq and test_warnings have been adjusted to use it, tests for
1589 other modules with both C and Python implementations in the stdlib
1590 can be adjusted to use it over time.

R. David Murray41448c52009-03-31 19:57:24 +00001598- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001599 that should cause a test to be skipped are now done using import_module

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001698- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1699 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1700 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1701 ``printf`` function, whereas PyString_FromFormat has an independent
1702 implementation and uses "%zd" on all platforms for size_t values.
1703 This makes a difference on win64, where ``printf`` needs "%Id" to display
1704 64bit values.
1705
Benjamin Peterson97179b02008-09-09 20:55:01 +00001706- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1707 error.
1708
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001709- Issue #3777: long() applied to a float object now always return a long
1710 object; previously an int would be returned for small values. the __long__
1711 method is allowed to return either an int or a long, but the behaviour of
1712 float objects should not change to respect backward compatibility.
1713
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001714- Issue #3751: str.rpartition would perform a left-partition when called with
1715 a unicode argument.
1716
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001717- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001719- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001720 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001721 was correctly parsed but parsing of subsequent arguments failed.
1722
Vinay Sajip35e3b032008-09-01 14:33:59 +00001723- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001724 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1725 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1726 when given a tuple of classes as second argument, were looking up
1727 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1728 type object.
1729
Neal Norwitz18aa3882008-08-24 05:04:52 +00001730- Fix crashes on memory allocation failure found with failmalloc.

1799 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1800 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001867What's New in Python 2.6 beta 3?
1868================================
1869
Barry Warsaw07a4a382008-08-21 01:15:08 +00001870*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001871
1872Core and Builtins
1873-----------------
1874
Guido van Rossumf8402962008-08-20 15:01:50 +00001875- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1876 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1877 extensions do not automatically benefit from the class attribute
1878 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1879 to their tp_flags field if they care. This is a backwards
1880 compatibility feature; in 3.0, all types will use the cache by
1881 default.
1882
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001883- Keyword arguments can now follow starred arguments. (``f(a, *args,
1884 keyword=23)`` is now valid syntax.)
1885
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001886- ctypes function pointers that are COM methods have a boolean True
1887 value again.
1888
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001889- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1890 by denying s# to parse objects that have a releasebuffer procedure,
1891 and introducing s*.
1892
Georg Brandl1e13ea92008-08-11 09:07:59 +00001893- Issue #3537: Fix an assertion failure when an empty but presized dict
1894 object was stored in the freelist.
1895
Mark Dickinsonb6467572008-08-04 21:30:09 +00001896- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1897 ValueError consistently across platforms.
1898
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001899- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1900 (64bit Unix, for example), unichr() would truncate its argument and return
1901 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1902
Neal Norwitze7d8be82008-07-31 17:17:14 +00001903- Apply security patches from Apple.
1904
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001905- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1906 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1907
Antoine Pitrou92f82162008-07-25 22:22:08 +00001908- Issue #1819: function calls with several named parameters are now on
1909 average 35% faster (as measured by pybench).
1910
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001911- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1912 the python debugger steps into a class statement: the free variables (local
1913 variables defined in an outer scope) would be deleted from the outer scope.
1914
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001915- Issue #2620: Overflow checking when allocating or reallocating memory
1916 was not always being done properly in some python types and extension
1917 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1918 all been updated to perform better checks and places in the code that
1919 would previously leak memory on the error path when such an allocation
1920 failed have been fixed.

1924
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001925- Issue #3612: Added some missing basic types in ctypes.wintypes.
1926
Benjamin Petersone977ad42008-08-20 01:42:01 +00001927- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1928 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1929
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001930- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1931 version reported by these tools does not necessarily follow the python
1932 version numbering scheme, so the module is less strict when parsing it.
1933
Nick Coghlanf70385a2008-08-18 12:42:46 +00001934- Issue #2235: Added Py3k warnings for types which will become unhashable
1935 under the stricter __hash__ inheritance rules in 3.0. Several types
1936 which did not meet the rules for hash invariants and were already
1937 unhashable in 3.0 have now been explicitly flagged as unhashable in
1938 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1939 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1940
Brett Cannon88f801d2008-08-18 00:46:22 +00001941- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1942 imported into the module but exposed as part of the module's API.
1943
Brett Cannon7b96f072008-08-18 00:41:11 +00001944- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1945
Brett Cannon46225e72008-08-18 00:36:52 +00001946- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1949
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001950- Issue #3575: Incremental decoder's decode function now takes bytearray
1951 by using 's*' instead of 't#'.
1952
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001953- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001954 fails unicode conversion on 2nd parameter. (windows only)
1955
Facundo Batista94f243a2008-08-17 03:38:39 +00001956- Issue 2464. urllib2 now supports a malformation in the URL received
1957 in a redirect.
1958
Brett Cannonabe423e2008-08-16 21:47:07 +00001959- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001960 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001961
Facundo Batistaeb90b782008-08-16 14:44:07 +00001962- Issue #2776: fixed small issue when handling an URL with double slash
1963 after a 302 response in the case of not going through a proxy.
1964
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001965- Issue #2676: in the email package, content-type parsing was hanging on
1966 pathological input because of quadratic or exponential behaviour of a
1967 regular expression.
1968
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001969- Issue #3476: binary buffered reading through the new "io" library is now
1970 thread-safe.
1971
Brett Cannonbf3157b2008-08-14 05:00:03 +00001972- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1973 since mimetools itself is deprecated. Because modules are cached, all
1974 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1975
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001976- Issue #3134: shutil referenced undefined WindowsError symbol.
1977
Robert Schuppenies14646332008-08-10 11:01:53 +00001978- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1979 menu entries were not deleted.
1980
Brett Cannon83e81842008-08-09 23:30:55 +00001981- Copied the implementation of reduce() to _functools.reduce() to have a
1982 version that did not raise a DeprecationWarning under -3.
1983
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001984- Issue #3205: When iterating over a BZ2File fails allocating memory, raise

Antoine Pitroude781a42008-08-09 12:43:23 +00002010 asking for a specific length. This problem only affected files opened

2067-----------------
2068
Georg Brandl3e483f62008-07-16 22:57:41 +00002069- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2070 its methods now allow for items objects that can be converted to
2071 an integer using operator.index().
2072
Mark Dickinson64b7e502008-07-16 09:40:03 +00002073- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2074 produced a ValueError instead of giving the correct float.
2075
Eric Smitha5fa5a22008-07-16 00:11:49 +00002076- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2077 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2078
Mark Dickinson7103aa42008-07-15 19:08:33 +00002079- Issue #3008: the float type has a new instance method 'float.hex'
2080 and a new class method 'float.fromhex' to convert floating-point
2081 numbers to and from hexadecimal strings, respectively.
2082
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002083- Issue #2235: __hash__ is once again inherited by default. To allow
2084 collections.Hashable to remain meaningful in the presence of the
2085 default hash implementation (object.__hash__), it is now possible
2086 to explicit block inheritance of hash by setting __hash__=None at
2087 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2088 level.
2089
Nick Coghlanb028f502008-07-13 14:52:36 +00002090- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2091 the parent module cannot be found while performing an absolute import.
2092 This means that an incorrectly defined __package__ attribute will
2093 now only prevent relative imports in that module rather than causing
2094 all imports from that module to fail.
2095
Nick Coghlan14ff9942008-07-08 14:21:42 +00002096- Issue #2517: Allow unicode messages in Exceptions again by correctly

2106 another thread's dictionary.
2107
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002108- Issue #3004: Minor change to slice.indices(): the start and stop
2109 arguments are now treated identically, making the behaviour easier
2110 to describe and understand. For example, slice(None, -10,
2111 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2112 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2113 10, -1).
2114
Georg Brandl278fc502008-07-19 12:46:12 +00002115- Issue #3219: Calling a function with repeated keyword arguments,
2116 f(a=2, a=23), would not cause a syntax error. This was a regression
2117 from 2.4 caused by the switch to the new compiler.

2128 error when they failed.
2129
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002130- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002155- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2156 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002157 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002158 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002174- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2562
Brett Cannonb61d8012008-05-11 23:39:04 +00002563- ``Lib/lib-old`` is now added to sys.path.
2564
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002565- On MacOS X it is now possible to install the framework in 64-bit
2566 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002567 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002568
2569 This is controlled by the configure argument ``--with-universal-archs``:
2570
2571 - ``--with-universal-archs=all``: install 4-way universal
2572
2573 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2574
2575 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2576
2577 This option should be used in combination with ``--enable-universalsdk=``.
2578
2579 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00002588
2589- The PyString functions have been renamed to PyBytes. A batch of
2590 defines were added so that the linker still sees the original
2591 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002629- Issue #1631171: Re-implement the 'warnings' module in C (the
2630 original Python code has been kept as backup). This will allow for
2631 using the 'warning's machinery in such places as the parser where
2632 use of pure Python code is not possible. Both the ``showarning()``
2633 and ``formatwarning()`` gain an optional 'line' argument which is
2634 not called by default for backwards-compatibility reasons. Setting
2635 ``warnings.showwarning()`` to an implementation that lacks support
2636 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002661- The getpass module has been improved on Unix. It now uses /dev/tty
2662 by default and uses stderr instead of stdout. A GetPassWarning is
2663 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002678- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002679 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002699- Issue #2550: The approach used by client/server code for obtaining
2700 ports to listen on in network-oriented tests has been refined in an
2701 effort to facilitate running multiple instances of the entire
2702 regression test suite in parallel without issue.
2703 test_support.bind_port() has been fixed such that it will always
2704 return a unique port -- which wasn't always the case with the
2705 previous implementation, especially if socket options had been set
2706 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2707 new implementation of bind_port() will actually raise an exception
2708 if it is passed an AF_INET/SOCK_STREAM socket with either the
2709 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2710 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2711 the socket it's been passed. This currently only applies to
2712 Windows. This option prevents any other sockets from binding to the
2713 host/port we've bound to, thus removing the possibility of the
2714 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2715 when a second SOCK_STREAM socket binds and accepts to a host/port
2716 that's already been bound by another socket. The optional preferred
2717 port parameter to bind_port() has been removed. Under no
2718 circumstances should tests be hard coding ports!
2719
2720 test_support.find_unused_port() has also been introduced, which will
2721 pass a temporary socket object to bind_port() in order to obtain an
2722 unused port. The temporary socket object is then closed and
2723 deleted, and the port is returned. This method should only be used
2724 for obtaining an unused port in order to pass to an external program
2725 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2726 a parameter to a server-oriented class that doesn't give you direct
2727 access to the underlying socket used.
2728
2729 Finally, test_support.HOST has been introduced, which should be used
2730 for the host argument of any relevant socket calls (i.e. bind and
2731 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002732
2733 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002734 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002735 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2736 test_asynchat and test_socket_ssl.
2737
Georg Brandl3ee81df2008-05-17 18:14:43 +00002738 It is now possible for multiple instances of the regression test
2739 suite to run in parallel without issue.

3006-----------------
3007
Fred Drakea8ee94b2008-03-01 02:45:07 +00003008- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003009 644. The mode is now inherited from the py file.

3012
3013- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003014
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003015- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003016 issue 215555 for a discussion.
3017
Eric Smitha73fbe72008-02-23 03:09:44 +00003018- Added the future_builtins module, which contains hex() and oct().
3019 These are the PEP 3127 version of these functions, designed to be
3020 compatible with the hex() and oct() builtins from Python 3.0. They
3021 differ slightly in their output formats from the existing, unchanged
3022 Python 2.6 builtins. The expected usage of the future_builtins
3023 module is:
3024 from future_builtins import hex, oct
3025
Eric Smith7ef40bf2008-02-20 23:34:22 +00003026- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3027 exponents for exponents with absolute value < 100. Follows C99
3028 standard. This is a change on Windows, which would use 3 digits.
3029 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3030 so that any alterations it does to the resulting string will be
3031 available in stringlib/formatter.h (for float.__format__).
3032
Eric Smith5a3c1352008-02-19 13:21:56 +00003033- Implemented PEP 3101, Advanced String Formatting. This adds a new
3034 builtin format(); a format() method for str and unicode; a
3035 __format__() method to object, str, unicode, int, long, float, and
3036 datetime; the class string.Formatter; and the C API
3037 PyObject_Format().
3038
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039- Fixed several potential crashes, all caused by specially crafted
3040 __del__ methods exploiting objects in temporarily inconsistent
3041 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003042
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003043- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003044 prevent a possible crash: an Abstract Base Class would try to access
3045 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003050- Clear all free lists during a gc.collect() of the highest generation
3051 in order to allow pymalloc to free more arenas. Python may give back
3052 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003053
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054- Issue #2045: Fix an infinite recursion triggered when printing a
3055 subclass of collections.defaultdict, if its default_factory is set
3056 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003057
Christian Heimesf75dbef2008-02-08 00:11:31 +00003058- Fixed a minor memory leak in dictobject.c. The content of the free
3059 list was not freed on interpreter shutdown.
3060
Georg Brandl3ee81df2008-05-17 18:14:43 +00003061- Limit free list of method and builtin function objects to 256
3062 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003063
Georg Brandl3ee81df2008-05-17 18:14:43 +00003064- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3065 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003066 to compact the internal free lists of pre-allocted ints and floats.
3067
Georg Brandl3ee81df2008-05-17 18:14:43 +00003068- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3069 calls. Python expected the return type int but the fork familie
3070 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003071
Georg Brandl3ee81df2008-05-17 18:14:43 +00003072- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003075- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3076 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003077
Georg Brandl3ee81df2008-05-17 18:14:43 +00003078- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3079 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003080
Georg Brandl3ee81df2008-05-17 18:14:43 +00003081- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3082 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003083
Georg Brandl3ee81df2008-05-17 18:14:43 +00003084- Patch #1473257: generator objects gain a gi_code attribute. This is
3085 the same object as the func_code attribute of the function that
3086 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003087
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088- Issue #1920: "while 0" statements were completely removed by the
3089 compiler, even in the presence of an "else" clause, which is
3090 supposed to be run when the condition is false. Now the compiler
3091 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003092
Guido van Rossumeead05f2008-01-24 18:21:02 +00003093- A few crashers fixed: weakref_in_del.py (issue #1377858);
3094 loosing_dict_ref.py (issue #1303614, test67.py);
3095 borrowed_ref_[34].py (not in tracker).
3096
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003097- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003098 suppressed while an extension is loaded by calling SetErrorMode in
3099 dynload_win.c. The error is still reported properly.
3100
Georg Brandl3ee81df2008-05-17 18:14:43 +00003101- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003102 several extension methods and modules do not work without unicode
3103 support.
3104
Georg Brandl26543b12008-01-21 18:36:51 +00003105- Issue #1882: when compiling code from a string, encoding cookies in the
3106 second line of code were not always recognized correctly.
3107
Georg Brandl14404b62008-01-19 19:27:05 +00003108- Issue #1679: "0x" was taken as a valid integer literal.
3109
Georg Brandl6caad7d2008-01-26 14:19:22 +00003110- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003111 added.
3112
Christian Heimesc94e2b52008-01-14 04:13:37 +00003113- sys.float_info / PyFloat_GetInfo: The floating point information
3114 object was converted from a dict to a specialized structseq object.
3115
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116- Patch #1816: Added sys.flags structseq. It exposes the status of
3117 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003118
Georg Brandl3ee81df2008-05-17 18:14:43 +00003119- Objects/structseq.c: Implemented new structseq representation. The
3120 patch makes structseqs (e.g. the return value of os.stat) more
3121 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003122
Georg Brandl3ee81df2008-05-17 18:14:43 +00003123- Patch #1700288: added a type attribute cache that caches method
3124 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003125
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003126- Bug #1776: __import__() no longer accepts filenames on any platform.
3127 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003128
Georg Brandlaed6c662008-01-07 17:25:53 +00003129- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3130
Georg Brandl3ee81df2008-05-17 18:14:43 +00003131- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3132 envvar and sys.dont_write_bytecode attribute. All these can be set
3133 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003134
Georg Brandl3ee81df2008-05-17 18:14:43 +00003135- Improve some exception messages when Windows fails to load an
3136 extension module. Now we get for example '%1 is not a valid Win32
3137 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003138

Georg Brandl3ee81df2008-05-17 18:14:43 +00003141- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3142 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003143
Christian Heimes0a8143f2007-12-18 23:22:54 +00003144- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003145 and INF. float("nan"), float("inf") and float("-inf") now work on
3146 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003147
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148- Compiler now generates simpler and faster code for dictionary
3149 literals. The oparg for BUILD_MAP now indicates an estimated
3150 dictionary size. There is a new opcode, STORE_MAP, for adding
3151 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003180- Patch #1739468: Directories and zipfiles containing a __main__.py
3181 file can now be directly executed by passing their name to the
3182 interpreter. The directory/zipfile is automatically inserted as the
3183 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003184
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Issue #1265: Fix a problem with sys.settrace, if the tracing
3186 function uses a generator expression when at the same time the
3187 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003188
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003189- sets and frozensets now have an isdisjoint() method.
3190

3192
Neal Norwitz44f326e2007-10-05 05:29:17 +00003193- Fix warnings found by the new version of the Coverity checker.
3194
Georg Brandl3ee81df2008-05-17 18:14:43 +00003195- The enumerate() builtin function is no longer bounded to sequences
3196 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3197 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003198
Georg Brandl3ee81df2008-05-17 18:14:43 +00003199- Issue #1686386: Tuple's tp_repr did not take into account the
3200 possibility of having a self-referential tuple, which is possible
3201 from C code. Nor did object's tp_str consider that a type's tp_str
3202 could do something that could lead to an inifinite recursion.
3203 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3204 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003205
Georg Brandl3ee81df2008-05-17 18:14:43 +00003206- Issue #1164: It was possible to trigger deadlock when using the
3207 'print' statement to write to a file since the GIL was not released
3208 as needed. Now PyObject_Print() does the right thing along with
3209 various tp_print implementations of the built-in types and those in
3210 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003211
Georg Brandl3ee81df2008-05-17 18:14:43 +00003212- Issue #1147: Exceptions were directly allowing string exceptions in
3213 their throw() method even though string exceptions no longer
3214 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003215
Georg Brandl3ee81df2008-05-17 18:14:43 +00003216- Issue #1096: Prevent a segfault from getting the repr of a very
3217 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003218
Brett Cannon1e534b52007-09-07 04:18:30 +00003219- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003220 PyObject_Call() never calling back out to Python code to trigger
3221 recursion depth updates/checks. Required the creation of a static
3222 RuntimeError instance in case normalizing an exception put the
3223 recursion check value past its limit. Fixes crashers
3224 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003225
Georg Brandl3ee81df2008-05-17 18:14:43 +00003226- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003239- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003240 __*__ attributes. (Some already existed, e.g., __doc__ and
3241 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003242
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003243- Add -3 option to the interpreter to warn about features that are
3244 deprecated and will be changed/removed in Python 3.0.
3245
Georg Brandl2134e752007-05-21 20:34:16 +00003246- Patch #1686487: you can now pass any mapping after '**' in function
3247 calls.
3248
Collin Winter62903052007-05-18 23:11:24 +00003249- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250 "except E as target:". This is to provide forwards compatibility
3251 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003252
Brett Cannon229cee22007-05-05 01:34:02 +00003253- Deprecate BaseException.message as per PEP 352.
3254
Georg Brandl3ee81df2008-05-17 18:14:43 +00003255- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003256 inherited from a builtin base.
3257
Vinay Sajip8549ce32007-05-06 17:53:37 +00003258- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003259 setting a plain string, ie don't expand to single letter identifiers.
3260
Raymond Hettinger13936692007-04-11 18:40:58 +00003261- Request #1191699: Slices can now be pickled.
3262
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003263- Request #1193128: str.translate() now allows a None argument for
3264 translations that only remove characters without re-mapping the
3265 remaining characters.
3266
Georg Brandl5cb76c12007-03-21 09:00:39 +00003267- Patch #1682205: a TypeError while unpacking an iterable is no longer
3268 masked by a generic one with the message "unpack non-sequence".
3269
Neal Norwitzaa754b72007-03-21 06:39:48 +00003270- Remove unused file Python/fmod.c.
3271
Guido van Rossum143b5642007-03-23 04:58:42 +00003272- Bug #1683368: The object.__init__() and object.__new__() methods are
3273 now stricter in rejecting excess arguments. The only time when
3274 either allows excess arguments is when it is not overridden and the
3275 other one is. For backwards compatibility, when both are
3276 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003277 warning later). Also, type.__init__() insists on the same signature
3278 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003279
Georg Brandl3ee81df2008-05-17 18:14:43 +00003280- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3281 object to complex using its __complex__() method before falling back
3282 to the __float__() method. Therefore, the functions in the cmath
3283 module now can operate on objects that define a __complex__()
3284 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003285
Georg Brandl3ee81df2008-05-17 18:14:43 +00003286- Patch #1623563: allow __class__ assignment for classes with
3287 __slots__. The old and the new class are still required to have the
3288 same slot names.

3294 ``object.__reduce_ex__()`` is called with an object that is faking
3295 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003296
Georg Brandl3ee81df2008-05-17 18:14:43 +00003297- Patch #1680015: Don't modify __slots__ tuple if it contains an

3301
Georg Brandl7b9c5552007-03-12 14:30:05 +00003302- Bug #1678647: write a newline after printing an exception in any
3303 case, even when converting the value to a string failed.
3304
Georg Brandl871f1bc2007-03-12 13:17:36 +00003305- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003306 its argument, if it exists. If not, it will work like before. This
3307 allows customizing the output of dir() in the presence of a
3308 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003310- Patch #922167: Python no longer segfaults when faced with infinitely
3311 self-recursive reload() calls (as reported by bug #742342).
3312
Georg Brandl3ee81df2008-05-17 18:14:43 +00003313- Patch #1675981: remove unreachable code from ``type.__new__()``

Facundo Batistad918a652007-04-24 13:54:38 +00003831- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003832 the client's request was successfully received, understood, and
3833 accepted. Now in these cases no error is raised in urllib (issue
3834 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003835

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003842- Added a timeout parameter to the constructor of other protocols
3843 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3844 work started with create_connection() and timeout in httplib, and
3845 closes patch #723312.
3846
Vinay Sajip8549ce32007-05-06 17:53:37 +00003847- Patch #1676823: Added create_connection() to socket.py, which may be

Facundo Batista07c78be2007-03-23 18:54:07 +00003850

Georg Brandl3ee81df2008-05-17 18:14:43 +00003873 AttributeError instead of an IOError when the server's response
3874 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003875

Georg Brandl3ee81df2008-05-17 18:14:43 +00003880- Patch #1429539: pdb now correctly initializes the __main__ module
3881 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003882 correctly now.
3883

3890
Georg Brandl3ee81df2008-05-17 18:14:43 +00003891- Patch #1530482: add pydoc.render_doc() which returns the
3892 documentation for a thing instead of paging it to stdout, which

3906
Georg Brandl92a6bae2007-03-13 17:43:32 +00003907- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003908 are set for invalid interpolation sequences that would lead to
3909 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003910

3926 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003944

3963
Georg Brandl3ee81df2008-05-17 18:14:43 +00003964- unittest now verifies more of its assumptions. In particular,
3965 TestCase and TestSuite subclasses (not instances) are no longer
3966 accepted in TestSuite.addTest(). This should cause no
3967 incompatibility since it never made sense with ordinary subclasses
3968 -- the failure just occurred later, with a more cumbersome
3969 exception.

3979
Georg Brandl3ee81df2008-05-17 18:14:43 +00003980- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00004358 time so that opening a database previously created with the DB_DUP
4359 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4360 opens. Specifically: dictionary assignment to a DB object will
4361 replace all values for a given key when the database allows
4362 duplicate values. DB users should use DB.put(k, v) when they want
4363 to store duplicates; not DB[k] = v.

4370 characters with ASCII value less than 32. Also, it correctly quotes
4371 dots only if they occur on a single line, as opposed to the previous
4372 behavior of quoting dots if they are the second character of any
4373 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004374
