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.

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__

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

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).

441 failures on systems with slightly bogus mtime behaviour.
442
Gregory P. Smith38f5d8f2009-11-01 18:33:55 +0000443- Issue #7246 & Issue #7208: getpass now properly flushes input before
444 reading from stdin so that existing input does not confuse it and
445 lead to incorrect entry or an IOError. It also properly flushes it
446 afterwards to avoid the terminal echoing the input afterwards on
447 OSes such as Solaris.

1562 leak-chasing test runs give sensible results. The previous method of
1563 reaping threads could return successfully while some Thread objects were
1564 still referenced. This also introduces a new private function:

1583 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

1591 it easy to import both normal and optimised versions of modules.
1592 test_heapq and test_warnings have been adjusted to use it, tests for
1593 other modules with both C and Python implementations in the stdlib

1702Core and Builtins
1703-----------------
1704
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001705- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1706
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001707- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1708 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1709 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1710 ``printf`` function, whereas PyString_FromFormat has an independent
1711 implementation and uses "%zd" on all platforms for size_t values.
1712 This makes a difference on win64, where ``printf`` needs "%Id" to display
1713 64bit values.
1714
Benjamin Peterson97179b02008-09-09 20:55:01 +00001715- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1716 error.
1717
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001718- Issue #3777: long() applied to a float object now always return a long
1719 object; previously an int would be returned for small values. the __long__
1720 method is allowed to return either an int or a long, but the behaviour of
1721 float objects should not change to respect backward compatibility.
1722
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001723- Issue #3751: str.rpartition would perform a left-partition when called with
1724 a unicode argument.
1725
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001726- Issue #3683: Fix compilation when --without-threads is given.
1727
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001728- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001729 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001730 was correctly parsed but parsing of subsequent arguments failed.
1731
Vinay Sajip35e3b032008-09-01 14:33:59 +00001732- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001733 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1734 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1735 when given a tuple of classes as second argument, were looking up
1736 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1737 type object.
1738
Neal Norwitz18aa3882008-08-24 05:04:52 +00001739- Fix crashes on memory allocation failure found with failmalloc.
1740
1741- Fix memory leaks found with valgrind and update suppressions file.
1742
1743- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1744
1745- Fix problem using wrong name in decimal module reported by pychecker.
1746
Christian Heimes7d4c3172008-08-22 19:47:25 +00001747- Silenced another compiler warning about a used but not defined
1748 function 'stringlib_contains_obj'.
1749
Benjamin Peterson712ee922008-08-24 18:10:20 +00001750- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1751 ``__delslice__``.
1752
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001753- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1754 library targets in the Makefile.
1755
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001756- Issue #1204: The configure script now tests for additional libraries
1757 that may be required when linking against readline. This fixes issues
1758 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
1759

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00001768- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
1769 stack usage in the case of deeply nested objects.
1770

1780
Nick Coghland2e09382008-09-11 12:11:06 +00001781- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001782 return a list or None rather than a custom object.
1783
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001784- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1808 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1809 for catch_warnings() also led to an improvement in the raising of a
1810 DeprecationWarning related to warnings.warn_explicit().
1811
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001812- The deprecation warnings for the old camelCase threading API were removed.

1840 exploitation of poor argument checking.
1841
Gerhard Häringef2276b2008-09-12 13:54:06 +00001842- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001876What's New in Python 2.6 beta 3?
1877================================
1878
Barry Warsaw07a4a382008-08-21 01:15:08 +00001879*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001880
1881Core and Builtins
1882-----------------
1883
Guido van Rossumf8402962008-08-20 15:01:50 +00001884- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1885 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1886 extensions do not automatically benefit from the class attribute
1887 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1888 to their tp_flags field if they care. This is a backwards
1889 compatibility feature; in 3.0, all types will use the cache by
1890 default.
1891
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001892- Keyword arguments can now follow starred arguments. (``f(a, *args,
1893 keyword=23)`` is now valid syntax.)
1894
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001895- ctypes function pointers that are COM methods have a boolean True
1896 value again.
1897
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001898- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1899 by denying s# to parse objects that have a releasebuffer procedure,
1900 and introducing s*.
1901
Georg Brandl1e13ea92008-08-11 09:07:59 +00001902- Issue #3537: Fix an assertion failure when an empty but presized dict
1903 object was stored in the freelist.
1904
Mark Dickinsonb6467572008-08-04 21:30:09 +00001905- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1906 ValueError consistently across platforms.
1907
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001908- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1909 (64bit Unix, for example), unichr() would truncate its argument and return
1910 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1911
Neal Norwitze7d8be82008-07-31 17:17:14 +00001912- Apply security patches from Apple.
1913
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001914- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1915 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1916
Antoine Pitrou92f82162008-07-25 22:22:08 +00001917- Issue #1819: function calls with several named parameters are now on
1918 average 35% faster (as measured by pybench).
1919
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001920- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1921 the python debugger steps into a class statement: the free variables (local
1922 variables defined in an outer scope) would be deleted from the outer scope.
1923
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001924- Issue #2620: Overflow checking when allocating or reallocating memory
1925 was not always being done properly in some python types and extension
1926 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1927 all been updated to perform better checks and places in the code that
1928 would previously leak memory on the error path when such an allocation
1929 failed have been fixed.
1930
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001931Library
1932-------
1933
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001934- Issue #3612: Added some missing basic types in ctypes.wintypes.
1935
Benjamin Petersone977ad42008-08-20 01:42:01 +00001936- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1937 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1938
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001939- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1940 version reported by these tools does not necessarily follow the python
1941 version numbering scheme, so the module is less strict when parsing it.
1942
Nick Coghlanf70385a2008-08-18 12:42:46 +00001943- Issue #2235: Added Py3k warnings for types which will become unhashable
1944 under the stricter __hash__ inheritance rules in 3.0. Several types
1945 which did not meet the rules for hash invariants and were already
1946 unhashable in 3.0 have now been explicitly flagged as unhashable in
1947 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1948 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1949
Brett Cannon88f801d2008-08-18 00:46:22 +00001950- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1951 imported into the module but exposed as part of the module's API.
1952
Brett Cannon7b96f072008-08-18 00:41:11 +00001953- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1954

1958
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001959- Issue #3575: Incremental decoder's decode function now takes bytearray
1960 by using 's*' instead of 't#'.
1961
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001962- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001963 fails unicode conversion on 2nd parameter. (windows only)
1964
Facundo Batista94f243a2008-08-17 03:38:39 +00001965- Issue 2464. urllib2 now supports a malformation in the URL received
1966 in a redirect.
1967
Brett Cannonabe423e2008-08-16 21:47:07 +00001968- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001969 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001970
Facundo Batistaeb90b782008-08-16 14:44:07 +00001971- Issue #2776: fixed small issue when handling an URL with double slash
1972 after a 302 response in the case of not going through a proxy.
1973
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001974- Issue #2676: in the email package, content-type parsing was hanging on
1975 pathological input because of quadratic or exponential behaviour of a
1976 regular expression.
1977
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001978- Issue #3476: binary buffered reading through the new "io" library is now
1979 thread-safe.
1980
Brett Cannonbf3157b2008-08-14 05:00:03 +00001981- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1982 since mimetools itself is deprecated. Because modules are cached, all
1983 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1984
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001985- Issue #3134: shutil referenced undefined WindowsError symbol.
1986
Robert Schuppenies14646332008-08-10 11:01:53 +00001987- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1988 menu entries were not deleted.

Antoine Pitroude781a42008-08-09 12:43:23 +00002019 asking for a specific length. This problem only affected files opened

2072
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002073*Release date: 17-Jul-2008*

2076-----------------
2077
Georg Brandl3e483f62008-07-16 22:57:41 +00002078- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2079 its methods now allow for items objects that can be converted to
2080 an integer using operator.index().
2081
Mark Dickinson64b7e502008-07-16 09:40:03 +00002082- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2083 produced a ValueError instead of giving the correct float.
2084
Eric Smitha5fa5a22008-07-16 00:11:49 +00002085- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2086 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2087
Mark Dickinson7103aa42008-07-15 19:08:33 +00002088- Issue #3008: the float type has a new instance method 'float.hex'
2089 and a new class method 'float.fromhex' to convert floating-point
2090 numbers to and from hexadecimal strings, respectively.
2091
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002092- Issue #2235: __hash__ is once again inherited by default. To allow
2093 collections.Hashable to remain meaningful in the presence of the
2094 default hash implementation (object.__hash__), it is now possible
2095 to explicit block inheritance of hash by setting __hash__=None at
2096 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2097 level.
2098
Nick Coghlanb028f502008-07-13 14:52:36 +00002099- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2100 the parent module cannot be found while performing an absolute import.
2101 This means that an incorrectly defined __package__ attribute will
2102 now only prevent relative imports in that module rather than causing
2103 all imports from that module to fail.
2104
Nick Coghlan14ff9942008-07-08 14:21:42 +00002105- Issue #2517: Allow unicode messages in Exceptions again by correctly

2114 threading.local: the first member set by a thread could be saved in
2115 another thread's dictionary.
2116
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002117- Issue #3004: Minor change to slice.indices(): the start and stop
2118 arguments are now treated identically, making the behaviour easier
2119 to describe and understand. For example, slice(None, -10,
2120 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2121 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2122 10, -1).
2123
Georg Brandl278fc502008-07-19 12:46:12 +00002124- Issue #3219: Calling a function with repeated keyword arguments,
2125 f(a=2, a=23), would not cause a syntax error. This was a regression
2126 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002127
Georg Brandl278fc502008-07-19 12:46:12 +00002128- Issue #2862: Make int and float freelist management consistent with
2129 other freelists. Changes their CompactFreeList apis into
2130 ClearFreeList apis and calls them via gc.collect().

2137 error when they failed.
2138
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002139- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002164- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2165 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002166 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002167 content-length. The problem had been corrected in the 2.4 branch, but never
2168 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002183- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2571
Brett Cannonb61d8012008-05-11 23:39:04 +00002572- ``Lib/lib-old`` is now added to sys.path.
2573
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002574- On MacOS X it is now possible to install the framework in 64-bit
2575 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002576 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002577
2578 This is controlled by the configure argument ``--with-universal-archs``:
2579
2580 - ``--with-universal-archs=all``: install 4-way universal
2581
2582 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2583
2584 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2585
2586 This option should be used in combination with ``--enable-universalsdk=``.
2587
2588 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 +00002597
2598- The PyString functions have been renamed to PyBytes. A batch of
2599 defines were added so that the linker still sees the original
2600 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002638- Issue #1631171: Re-implement the 'warnings' module in C (the
2639 original Python code has been kept as backup). This will allow for
2640 using the 'warning's machinery in such places as the parser where
2641 use of pure Python code is not possible. Both the ``showarning()``
2642 and ``formatwarning()`` gain an optional 'line' argument which is
2643 not called by default for backwards-compatibility reasons. Setting
2644 ``warnings.showwarning()`` to an implementation that lacks support
2645 for the ``line`` argument will raise a DeprecationWarning.

2669
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002670- The getpass module has been improved on Unix. It now uses /dev/tty
2671 by default and uses stderr instead of stdout. A GetPassWarning is
2672 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002673

2684 implementation detail of the public ``types`` module, has been
2685 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00002686
Georg Brandl3ee81df2008-05-17 18:14:43 +00002687- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002688 extension modules between 32 and 64 bit platforms. See the distutls
2689 build documentation for more information.

2692 threads at once without fear of crashing the Python interpreter. If
2693 file.close() is called while an object is in use by another thread
2694 an IOError exception will be raised and the file will not be closed.
2695
Thomas Hellerf7906482008-04-04 19:43:25 +00002696- The bundled libffi copy is now in sync with the recently released

2701 so the controlled environment will more closely mirror the typical
2702 script environment. This supports setup.py scripts that refer to
2703 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002708- Issue #2550: The approach used by client/server code for obtaining
2709 ports to listen on in network-oriented tests has been refined in an
2710 effort to facilitate running multiple instances of the entire
2711 regression test suite in parallel without issue.
2712 test_support.bind_port() has been fixed such that it will always
2713 return a unique port -- which wasn't always the case with the
2714 previous implementation, especially if socket options had been set
2715 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2716 new implementation of bind_port() will actually raise an exception
2717 if it is passed an AF_INET/SOCK_STREAM socket with either the
2718 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2719 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2720 the socket it's been passed. This currently only applies to
2721 Windows. This option prevents any other sockets from binding to the
2722 host/port we've bound to, thus removing the possibility of the
2723 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2724 when a second SOCK_STREAM socket binds and accepts to a host/port
2725 that's already been bound by another socket. The optional preferred
2726 port parameter to bind_port() has been removed. Under no
2727 circumstances should tests be hard coding ports!
2728
2729 test_support.find_unused_port() has also been introduced, which will
2730 pass a temporary socket object to bind_port() in order to obtain an
2731 unused port. The temporary socket object is then closed and
2732 deleted, and the port is returned. This method should only be used
2733 for obtaining an unused port in order to pass to an external program
2734 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2735 a parameter to a server-oriented class that doesn't give you direct
2736 access to the underlying socket used.
2737
2738 Finally, test_support.HOST has been introduced, which should be used
2739 for the host argument of any relevant socket calls (i.e. bind and
2740 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002741
2742 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002743 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002744 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2745 test_asynchat and test_socket_ssl.
2746
Georg Brandl3ee81df2008-05-17 18:14:43 +00002747 It is now possible for multiple instances of the regression test
2748 suite to run in parallel without issue.

3015-----------------
3016
Fred Drakea8ee94b2008-03-01 02:45:07 +00003017- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003018 644. The mode is now inherited from the py file.

3021
3022- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003023
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003024- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003025 issue 215555 for a discussion.
3026
Eric Smitha73fbe72008-02-23 03:09:44 +00003027- Added the future_builtins module, which contains hex() and oct().
3028 These are the PEP 3127 version of these functions, designed to be
3029 compatible with the hex() and oct() builtins from Python 3.0. They
3030 differ slightly in their output formats from the existing, unchanged
3031 Python 2.6 builtins. The expected usage of the future_builtins
3032 module is:
3033 from future_builtins import hex, oct
3034
Eric Smith7ef40bf2008-02-20 23:34:22 +00003035- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3036 exponents for exponents with absolute value < 100. Follows C99
3037 standard. This is a change on Windows, which would use 3 digits.
3038 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3039 so that any alterations it does to the resulting string will be
3040 available in stringlib/formatter.h (for float.__format__).
3041
Eric Smith5a3c1352008-02-19 13:21:56 +00003042- Implemented PEP 3101, Advanced String Formatting. This adds a new
3043 builtin format(); a format() method for str and unicode; a
3044 __format__() method to object, str, unicode, int, long, float, and
3045 datetime; the class string.Formatter; and the C API
3046 PyObject_Format().
3047
Georg Brandl3ee81df2008-05-17 18:14:43 +00003048- Fixed several potential crashes, all caused by specially crafted
3049 __del__ methods exploiting objects in temporarily inconsistent
3050 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003051
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003052- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003053 prevent a possible crash: an Abstract Base Class would try to access
3054 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Clear all free lists during a gc.collect() of the highest generation
3060 in order to allow pymalloc to free more arenas. Python may give back
3061 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003062
Georg Brandl3ee81df2008-05-17 18:14:43 +00003063- Issue #2045: Fix an infinite recursion triggered when printing a
3064 subclass of collections.defaultdict, if its default_factory is set
3065 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003066
Christian Heimesf75dbef2008-02-08 00:11:31 +00003067- Fixed a minor memory leak in dictobject.c. The content of the free
3068 list was not freed on interpreter shutdown.
3069
Georg Brandl3ee81df2008-05-17 18:14:43 +00003070- Limit free list of method and builtin function objects to 256
3071 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003072
Georg Brandl3ee81df2008-05-17 18:14:43 +00003073- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3074 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003075 to compact the internal free lists of pre-allocted ints and floats.
3076
Georg Brandl3ee81df2008-05-17 18:14:43 +00003077- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3078 calls. Python expected the return type int but the fork familie
3079 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003080
Georg Brandl3ee81df2008-05-17 18:14:43 +00003081- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3082 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003083
Georg Brandl3ee81df2008-05-17 18:14:43 +00003084- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3085 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3088 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003089
Georg Brandl3ee81df2008-05-17 18:14:43 +00003090- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3091 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003092
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093- Patch #1473257: generator objects gain a gi_code attribute. This is
3094 the same object as the func_code attribute of the function that
3095 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003096
Georg Brandl3ee81df2008-05-17 18:14:43 +00003097- Issue #1920: "while 0" statements were completely removed by the
3098 compiler, even in the presence of an "else" clause, which is
3099 supposed to be run when the condition is false. Now the compiler
3100 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003101
Guido van Rossumeead05f2008-01-24 18:21:02 +00003102- A few crashers fixed: weakref_in_del.py (issue #1377858);
3103 loosing_dict_ref.py (issue #1303614, test67.py);
3104 borrowed_ref_[34].py (not in tracker).
3105
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003106- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003107 suppressed while an extension is loaded by calling SetErrorMode in
3108 dynload_win.c. The error is still reported properly.
3109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003111 several extension methods and modules do not work without unicode
3112 support.
3113
Georg Brandl26543b12008-01-21 18:36:51 +00003114- Issue #1882: when compiling code from a string, encoding cookies in the
3115 second line of code were not always recognized correctly.
3116
Georg Brandl14404b62008-01-19 19:27:05 +00003117- Issue #1679: "0x" was taken as a valid integer literal.
3118
Georg Brandl6caad7d2008-01-26 14:19:22 +00003119- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003120 added.
3121
Christian Heimesc94e2b52008-01-14 04:13:37 +00003122- sys.float_info / PyFloat_GetInfo: The floating point information
3123 object was converted from a dict to a specialized structseq object.
3124
Georg Brandl3ee81df2008-05-17 18:14:43 +00003125- Patch #1816: Added sys.flags structseq. It exposes the status of
3126 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003127
Georg Brandl3ee81df2008-05-17 18:14:43 +00003128- Objects/structseq.c: Implemented new structseq representation. The
3129 patch makes structseqs (e.g. the return value of os.stat) more
3130 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003131
Georg Brandl3ee81df2008-05-17 18:14:43 +00003132- Patch #1700288: added a type attribute cache that caches method
3133 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003134
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003135- Bug #1776: __import__() no longer accepts filenames on any platform.
3136 The first parameter to __import__() must be a valid module name.

3141 envvar and sys.dont_write_bytecode attribute. All these can be set
3142 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003143
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144- Improve some exception messages when Windows fails to load an
3145 extension module. Now we get for example '%1 is not a valid Win32
3146 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003147

Christian Heimes0a8143f2007-12-18 23:22:54 +00003153- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154 and INF. float("nan"), float("inf") and float("-inf") now work on
3155 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003156
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157- Compiler now generates simpler and faster code for dictionary
3158 literals. The oparg for BUILD_MAP now indicates an estimated
3159 dictionary size. There is a new opcode, STORE_MAP, for adding
3160 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003189- Patch #1739468: Directories and zipfiles containing a __main__.py
3190 file can now be directly executed by passing their name to the
3191 interpreter. The directory/zipfile is automatically inserted as the
3192 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003193
Georg Brandl3ee81df2008-05-17 18:14:43 +00003194- Issue #1265: Fix a problem with sys.settrace, if the tracing
3195 function uses a generator expression when at the same time the
3196 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003197
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003198- sets and frozensets now have an isdisjoint() method.
3199

3201
Neal Norwitz44f326e2007-10-05 05:29:17 +00003202- Fix warnings found by the new version of the Coverity checker.
3203
Georg Brandl3ee81df2008-05-17 18:14:43 +00003204- The enumerate() builtin function is no longer bounded to sequences
3205 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3206 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003207
Georg Brandl3ee81df2008-05-17 18:14:43 +00003208- Issue #1686386: Tuple's tp_repr did not take into account the
3209 possibility of having a self-referential tuple, which is possible
3210 from C code. Nor did object's tp_str consider that a type's tp_str
3211 could do something that could lead to an inifinite recursion.
3212 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3213 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003214
Georg Brandl3ee81df2008-05-17 18:14:43 +00003215- Issue #1164: It was possible to trigger deadlock when using the
3216 'print' statement to write to a file since the GIL was not released
3217 as needed. Now PyObject_Print() does the right thing along with
3218 various tp_print implementations of the built-in types and those in
3219 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003220
Georg Brandl3ee81df2008-05-17 18:14:43 +00003221- Issue #1147: Exceptions were directly allowing string exceptions in
3222 their throw() method even though string exceptions no longer
3223 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003224
Georg Brandl3ee81df2008-05-17 18:14:43 +00003225- Issue #1096: Prevent a segfault from getting the repr of a very
3226 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003227
Brett Cannon1e534b52007-09-07 04:18:30 +00003228- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003229 PyObject_Call() never calling back out to Python code to trigger
3230 recursion depth updates/checks. Required the creation of a static
3231 RuntimeError instance in case normalizing an exception put the
3232 recursion check value past its limit. Fixes crashers
3233 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003234
Georg Brandl3ee81df2008-05-17 18:14:43 +00003235- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003248- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003249 __*__ attributes. (Some already existed, e.g., __doc__ and
3250 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003251
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003252- Add -3 option to the interpreter to warn about features that are
3253 deprecated and will be changed/removed in Python 3.0.
3254
Georg Brandl2134e752007-05-21 20:34:16 +00003255- Patch #1686487: you can now pass any mapping after '**' in function
3256 calls.
3257
Collin Winter62903052007-05-18 23:11:24 +00003258- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003259 "except E as target:". This is to provide forwards compatibility
3260 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003261
Brett Cannon229cee22007-05-05 01:34:02 +00003262- Deprecate BaseException.message as per PEP 352.
3263
Georg Brandl3ee81df2008-05-17 18:14:43 +00003264- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003265 inherited from a builtin base.
3266
Vinay Sajip8549ce32007-05-06 17:53:37 +00003267- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003268 setting a plain string, ie don't expand to single letter identifiers.
3269
Raymond Hettinger13936692007-04-11 18:40:58 +00003270- Request #1191699: Slices can now be pickled.
3271
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003272- Request #1193128: str.translate() now allows a None argument for
3273 translations that only remove characters without re-mapping the
3274 remaining characters.
3275
Georg Brandl5cb76c12007-03-21 09:00:39 +00003276- Patch #1682205: a TypeError while unpacking an iterable is no longer
3277 masked by a generic one with the message "unpack non-sequence".
3278
Neal Norwitzaa754b72007-03-21 06:39:48 +00003279- Remove unused file Python/fmod.c.
3280
Guido van Rossum143b5642007-03-23 04:58:42 +00003281- Bug #1683368: The object.__init__() and object.__new__() methods are
3282 now stricter in rejecting excess arguments. The only time when
3283 either allows excess arguments is when it is not overridden and the
3284 other one is. For backwards compatibility, when both are
3285 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003286 warning later). Also, type.__init__() insists on the same signature
3287 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003288
Georg Brandl3ee81df2008-05-17 18:14:43 +00003289- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3290 object to complex using its __complex__() method before falling back
3291 to the __float__() method. Therefore, the functions in the cmath
3292 module now can operate on objects that define a __complex__()
3293 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003294
Georg Brandl3ee81df2008-05-17 18:14:43 +00003295- Patch #1623563: allow __class__ assignment for classes with
3296 __slots__. The old and the new class are still required to have the
3297 same slot names.

3303 ``object.__reduce_ex__()`` is called with an object that is faking
3304 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003305
Georg Brandl3ee81df2008-05-17 18:14:43 +00003306- Patch #1680015: Don't modify __slots__ tuple if it contains an

3310
Georg Brandl7b9c5552007-03-12 14:30:05 +00003311- Bug #1678647: write a newline after printing an exception in any
3312 case, even when converting the value to a string failed.
3313
Georg Brandl871f1bc2007-03-12 13:17:36 +00003314- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003315 its argument, if it exists. If not, it will work like before. This
3316 allows customizing the output of dir() in the presence of a
3317 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003319- Patch #922167: Python no longer segfaults when faced with infinitely
3320 self-recursive reload() calls (as reported by bug #742342).
3321

Georg Brandl4e933132006-09-06 20:05:58 +00003432- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Guido van Rossum8bc09652008-02-21 18:18:37 +00003491- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00003841 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004367 time so that opening a database previously created with the DB_DUP
4368 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4369 opens. Specifically: dictionary assignment to a DB object will
4370 replace all values for a given key when the database allows
4371 duplicate values. DB users should use DB.put(k, v) when they want
4372 to store duplicates; not DB[k] = v.

4379 characters with ASCII value less than 32. Also, it correctly quotes
4380 dots only if they occur on a single line, as opposed to the previous
4381 behavior of quoting dots if they are the second character of any
4382 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004383
