12Core and Builtins
13-----------------
14
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000015- Issue #7085: Fix crash when importing some extensions in a thread

17
Mark Dickinsonbd15a062009-11-18 19:33:35 +000018- Issue #7117: Backport round implementation from Python 3.x. round
19 now uses David Gay's correctly-rounded string <-> double conversions
20 (when available), and so produces correctly rounded results. There
21 are two related small changes: (1) round now accepts any class with
22 an __index__ method for its second argument (but no longer accepts
23 floats for the second argument), and (2) an excessively large second
24 integer argument (e.g., round(1.234, 10**100)) no longer raises an
25 exception.
26

154 statement and correctly lookup the __enter__ and __exit__ special methods.
155
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000156- Issue #5829: complex("1e500") no longer raises OverflowError. This
157 makes it consistent with float("1e500") and interpretation of real

169 rejected; (2) parsing of strings representing infinities and nans
170 was locale aware; and (3) the interpretation of fromhex('-nan')
171 didn't match that of float('-nan').
172
Eric Smitha985a3a2009-05-05 18:26:08 +0000173- Issue #5920: For float.__format__, change the behavior with the
174 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
175 to be like 'g' but with at least one decimal point and with a
176 default precision of 12. Previously, the behavior the same but with
177 a default precision of 6. This more closely matches str(), and
178 reduces surprises when adding alignment flags to the empty
179 presentation type. This also affects the new complex.__format__ in
180 the same way.
181
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000182- Issue #5890: in subclasses of 'property' the __doc__ attribute was

191
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000192- Issue #5864: Fix empty format code formatting for floats so that it

207 z involves nans, infs or negative zeros.
208
Eric Smithaca19e62009-04-22 13:29:05 +0000209- Implement PEP 378, Format Specifier for Thousands Separator, for
210 floats, ints, and longs.
211
212- Issue #5515: 'n' formatting for ints, longs, and floats handles
213 leading zero formatting poorly.
214
215- Issue #5772: For float.__format__, don't add a trailing ".0" if
216 we're using no type code and we have an exponent.

222 some builtin types.
223
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000224- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000225 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000226
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000227- Issue #5759: float() didn't call __float__ on str subclasses.

246 reduce the size of collections and therefore the garbage collection overhead
247 on long-running programs, depending on their particular use of datatypes.
248
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000249- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

254 2**15 for the internal representation of integers, for performance
255 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
256 --enable-big-digits option to configure, which overrides the
257 default. Add sys.long_info structseq to provide information about
258 the internal format.
259

269
Brett Cannon6c4cff02009-03-11 04:51:06 +0000270- Issue #3652: Make the 'line' argument for warnings.showwarning() a
271 requirement. Means the DeprecationWarning from Python 2.6 can go away.

282 on a 64-bit system.
283
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000284- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

Georg Brandl29c6a282009-04-05 20:23:13 +0000292- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000293 were suppressing all exceptions. These include list(), filter(), map(),

Antoine Pitrouc2f02212009-01-13 23:13:52 +0000304- Issue #4935: The overflow checking code in the expandtabs() method common
305 to str, bytes and bytearray could be optimized away by the compiler, letting
306 the interpreter segfault instead of raising an error.
307
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000308- Issue #3720: Fix a crash when an iterator modifies its class and removes its
309 __next__ method.

314
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000315- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
316 collecting the oldest generation) so that allocating lots of objects without
317 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000318 Martin von Löwis at

322
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000323- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
324 an existing .py counterpart, override the co_filename attributes of all
325 code objects if the original filename is obsolete (which can happen if the
326 file has been renamed, moved, or if it is accessed through different paths).
327 Patch by Ziga Seilnacht and Jean-Paul Calderone.
328
Martin v. Löwis5344c992009-01-02 20:32:55 +0000329- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000331- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
332 file with `str' filename on Windows.
333
Antoine Pitrouaa687902009-01-01 14:11:22 +0000334- Issue #3680: Reference cycles created through a dict, set or deque iterator

336
Nick Coghlan180e4002008-12-30 01:18:48 +0000337- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
338 where the tp_hash and tp_dict slots are both NULL.
339
Benjamin Peterson7af65562008-12-29 17:56:58 +0000340- Issue #4764: With io.open, IOError.filename is set when trying to open a

347 bytearray.translate(). It was always allowed for bytes.translate().
348
Skip Montanarof205c132008-12-23 03:30:15 +0000349- Added test case to ensure attempts to read from a file opened for writing
350 fail.
351

362 context manager returns a value that cannot be converted to a bool.
363
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000364- Issue #4597: Fixed several opcodes that weren't always propagating
365 exceptions.
366
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000367- Issue #4445: Replace "sizeof(PyStringObject)" with
368 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
369 str instances. On a typical machine this saves 3 bytes of memory
370 (on average) per string allocation.
371
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000372- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
373 interpreter to abort ("Fatal Python error: Could not reset the stack!")
374 instead of throwing a MemoryError.
375
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000376- Issue #3689: The list reversed iterator now supports __length_hint__
377 instead of __len__. Behavior now matches other reversed iterators.
378
Benjamin Petersonc078f922008-11-21 22:27:24 +0000379- Issue #4367: Python would segfault during compiling when the unicodedata
380 module couldn't be imported and \N escapes were present.
381
Vinay Sajip213faca2008-12-03 23:22:58 +0000382- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000383 method on file objects with closefd=False. The file descriptor is still
384 kept open but the file object behaves like a closed file. The ``FileIO``
385 object also got a new readonly attribute ``closefd``.
386
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000387- Issue #4348: Some bytearray methods returned that didn't cause any change to
388 the bytearray, returned the same bytearray instead of a copy.
389
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000390- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
391
Benjamin Peterson273c2332008-11-17 22:39:09 +0000392- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
393
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000394- Issue #4048: The parser module now correctly validates relative imports.
395
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000396- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

398
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000399- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
400 method does not return iterators for the 4th and 5th items.
401
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000402- Issue #4209: Enabling unicode_literals and the print_function in the same
403 __future__ import didn't work.
404
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000405- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000406 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000407
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000408- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
409 returned a path longer than MAX_PATH. (But It's doubtful this code path is
410 really executed because I cannot move to such directory on win2k)
411
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000412- Issue #4069: When set.remove(element) is used with a set element, the element
413 is temporarily replaced with an equivalent frozenset. But the eventual
414 KeyError would always report the empty frozenset([]) as the missing key. Now
415 it correctly refers to the initial element.
416
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000417- Issue #4509: Various issues surrounding resize of bytearray objects to
418 which there are buffer exports.
419

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000432- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
433 returned them on 64bit platforms.
434
Walter Dörwalded960ac2009-05-03 22:36:33 +0000435- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
436 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
437 step. This avoids problems with counting UTF-8 bytes that ignores the effect
438 of using the replace error handler in PyUnicode_DecodeUTF8().
439
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000440- Issue #3739: The unicode-internal encoder now reports the number of characters
441 consumed like any other encoder (instead of the number of bytes).

Nick Coghlan49868cb2009-11-15 07:30:34 +0000466- Issue #6816: runpy now provides a run_path function that allows Python code
467 to execute file paths that refer to source or compiled Python files as well
468 as zipfiles, directories and other valid sys.path entries that contain a
469 __main__.py file. This allows applications that run other Python scripts to

1625 leak-chasing test runs give sensible results. The previous method of
1626 reaping threads could return successfully while some Thread objects were

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001768- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1769
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001770- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1771 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1772 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1773 ``printf`` function, whereas PyString_FromFormat has an independent
1774 implementation and uses "%zd" on all platforms for size_t values.
1775 This makes a difference on win64, where ``printf`` needs "%Id" to display
1776 64bit values.
1777
Benjamin Peterson97179b02008-09-09 20:55:01 +00001778- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001781- Issue #3777: long() applied to a float object now always return a long
1782 object; previously an int would be returned for small values. the __long__
1783 method is allowed to return either an int or a long, but the behaviour of
1784 float objects should not change to respect backward compatibility.
1785
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001786- Issue #3751: str.rpartition would perform a left-partition when called with
1787 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001792 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001793 was correctly parsed but parsing of subsequent arguments failed.
1794
Vinay Sajip35e3b032008-09-01 14:33:59 +00001795- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001796 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1797 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1798 when given a tuple of classes as second argument, were looking up
1799 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1800 type object.
1801
Neal Norwitz18aa3882008-08-24 05:04:52 +00001802- Fix crashes on memory allocation failure found with failmalloc.

1871 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1872 for catch_warnings() also led to an improvement in the raising of a

1945-----------------
1946
Guido van Rossumf8402962008-08-20 15:01:50 +00001947- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1948 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1949 extensions do not automatically benefit from the class attribute
1950 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1951 to their tp_flags field if they care. This is a backwards
1952 compatibility feature; in 3.0, all types will use the cache by
1953 default.
1954
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001955- Keyword arguments can now follow starred arguments. (``f(a, *args,
1956 keyword=23)`` is now valid syntax.)
1957
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001958- ctypes function pointers that are COM methods have a boolean True
1959 value again.
1960
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001961- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1962 by denying s# to parse objects that have a releasebuffer procedure,
1963 and introducing s*.
1964
Georg Brandl1e13ea92008-08-11 09:07:59 +00001965- Issue #3537: Fix an assertion failure when an empty but presized dict
1966 object was stored in the freelist.
1967
Mark Dickinsonb6467572008-08-04 21:30:09 +00001968- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1969 ValueError consistently across platforms.
1970
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001971- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1972 (64bit Unix, for example), unichr() would truncate its argument and return
1973 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1974
Neal Norwitze7d8be82008-07-31 17:17:14 +00001975- Apply security patches from Apple.
1976
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001977- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1978 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1979
Antoine Pitrou92f82162008-07-25 22:22:08 +00001980- Issue #1819: function calls with several named parameters are now on
1981 average 35% faster (as measured by pybench).
1982
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001983- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1984 the python debugger steps into a class statement: the free variables (local
1985 variables defined in an outer scope) would be deleted from the outer scope.
1986
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001987- Issue #2620: Overflow checking when allocating or reallocating memory
1988 was not always being done properly in some python types and extension
1989 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1990 all been updated to perform better checks and places in the code that
1991 would previously leak memory on the error path when such an allocation

2000 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2001
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002002- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2003 version reported by these tools does not necessarily follow the python
2004 version numbering scheme, so the module is less strict when parsing it.
2005
Nick Coghlanf70385a2008-08-18 12:42:46 +00002006- Issue #2235: Added Py3k warnings for types which will become unhashable
2007 under the stricter __hash__ inheritance rules in 3.0. Several types
2008 which did not meet the rules for hash invariants and were already
2009 unhashable in 3.0 have now been explicitly flagged as unhashable in
2010 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2011 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2012
Brett Cannon88f801d2008-08-18 00:46:22 +00002013- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2014 imported into the module but exposed as part of the module's API.
2015

2021
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002022- Issue #3575: Incremental decoder's decode function now takes bytearray
2023 by using 's*' instead of 't#'.
2024
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002025- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002026 fails unicode conversion on 2nd parameter. (windows only)
2027
Facundo Batista94f243a2008-08-17 03:38:39 +00002028- Issue 2464. urllib2 now supports a malformation in the URL received
2029 in a redirect.

2035 after a 302 response in the case of not going through a proxy.
2036
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002037- Issue #2676: in the email package, content-type parsing was hanging on
2038 pathological input because of quadratic or exponential behaviour of a
2039 regular expression.
2040
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002041- Issue #3476: binary buffered reading through the new "io" library is now
2042 thread-safe.
2043
Brett Cannonbf3157b2008-08-14 05:00:03 +00002044- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2045 since mimetools itself is deprecated. Because modules are cached, all
2046 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2047
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002048- Issue #3134: shutil referenced undefined WindowsError symbol.
2049
Robert Schuppenies14646332008-08-10 11:01:53 +00002050- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2051 menu entries were not deleted.
2052
Brett Cannon83e81842008-08-09 23:30:55 +00002053- Copied the implementation of reduce() to _functools.reduce() to have a
2054 version that did not raise a DeprecationWarning under -3.
2055
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002056- Issue #3205: When iterating over a BZ2File fails allocating memory, raise

Guido van Rossum59ce9012008-08-09 14:55:34 +00002059- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2060 to _sre.compile() will now be rejected. This should not affect anybody
2061 since the re.compile() function never generates invalid re-bytecode.
2062
Skip Montanaroa032bf42008-08-08 22:52:51 +00002063- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2064 upon first access it can be automatically initialized from the csv file if
2065 it wasn't initialized during instantiation.
2066
Brett Cannon3aa2a492008-08-06 22:28:09 +00002067- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2068 the reload() built-in has been removed.
2069
Brett Cannon7e30b672008-08-04 21:52:25 +00002070- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002071 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2079 raised an AttributeError.
2080
Benjamin Peterson01a24322008-07-28 23:35:27 +00002081- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002082 asking for a specific length. This problem only affected files opened
2083 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002084
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002085- Issue #3449: Update decimal module to use most recent specification

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002108- Issue #3394: zipfile.writestr sets external attributes when passed a
2109 file name rather than a ZipInfo instance, so files are extracted with
2110 mode 0600 rather than 000 under Unix.
2111
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002112- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2113 argument in python 2.5, this broke code that subclassed Popen to include its

2125 interaction with the tp_hash slot (added in 2.6b2) are now documented
2126
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002127- Issue #643841: The language reference now provides more detailed
2128 coverage of the lookup process for special methods. The disclaimers
2129 regarding lack of coverage of new-style classes have also been
2130 removed, since the coverage is now fairly reasonable.

2134================================
2135
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002136*Release date: 17-Jul-2008*
2137
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002138Core and Builtins
2139-----------------
2140
Georg Brandl3e483f62008-07-16 22:57:41 +00002141- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2142 its methods now allow for items objects that can be converted to
2143 an integer using operator.index().
2144
Mark Dickinson64b7e502008-07-16 09:40:03 +00002145- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2146 produced a ValueError instead of giving the correct float.
2147
Eric Smitha5fa5a22008-07-16 00:11:49 +00002148- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2149 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2150
Mark Dickinson7103aa42008-07-15 19:08:33 +00002151- Issue #3008: the float type has a new instance method 'float.hex'
2152 and a new class method 'float.fromhex' to convert floating-point
2153 numbers to and from hexadecimal strings, respectively.
2154
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002155- Issue #2235: __hash__ is once again inherited by default. To allow
2156 collections.Hashable to remain meaningful in the presence of the
2157 default hash implementation (object.__hash__), it is now possible
2158 to explicit block inheritance of hash by setting __hash__=None at
2159 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2160 level.
2161
Nick Coghlanb028f502008-07-13 14:52:36 +00002162- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2163 the parent module cannot be found while performing an absolute import.
2164 This means that an incorrectly defined __package__ attribute will
2165 now only prevent relative imports in that module rather than causing
2166 all imports from that module to fail.
2167
Nick Coghlan14ff9942008-07-08 14:21:42 +00002168- Issue #2517: Allow unicode messages in Exceptions again by correctly
2169 bypassing the instance dictionary when looking up __unicode__ on
2170 new-style classes.
2171
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002172- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2173 set to a custom object whose write() method happens to install
2174 another file in sys.stdout.
2175
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002176- Issue #3088: Corrected a race condition in classes derived from
2177 threading.local: the first member set by a thread could be saved in
2178 another thread's dictionary.
2179
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002180- Issue #3004: Minor change to slice.indices(): the start and stop
2181 arguments are now treated identically, making the behaviour easier
2182 to describe and understand. For example, slice(None, -10,
2183 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2184 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2185 10, -1).
2186
Georg Brandl278fc502008-07-19 12:46:12 +00002187- Issue #3219: Calling a function with repeated keyword arguments,
2188 f(a=2, a=23), would not cause a syntax error. This was a regression
2189 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002190
Georg Brandl278fc502008-07-19 12:46:12 +00002191- Issue #2862: Make int and float freelist management consistent with
2192 other freelists. Changes their CompactFreeList apis into
2193 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002194

2196-------
2197
Thomas Heller57adf222008-08-14 19:10:48 +00002198- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2199 api functions without holding the GIL, which could lead to a fatal
2200 error when they failed.
2201
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002202- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002210- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2211 ForkingPickler.register() to resolve conflict with ctypes.
2212
Vinay Sajip51e65192008-07-18 09:01:10 +00002213- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002214
Thomas Heller880f5292008-07-15 19:39:38 +00002215- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2216 a valid dlerror() message.
2217
Thomas Heller2bad6572008-07-15 17:19:50 +00002218- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2219 incomplete structure was created.
2220

2224
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002225- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002226
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002227- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2228 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002229 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002230 content-length. The problem had been corrected in the 2.4 branch, but never
2231 merged into trunk.
2232
Georg Brandle78fbcc2008-07-05 10:13:36 +00002233- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002244 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002245
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002246- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2247 handling is now the same as that of other special attributes like __name__).
2248
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002249- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2250 removal in Python 3.0 in favor of urllib2.urlopen().

2261 default https port (443).
2262
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00002263- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl5cc774e2008-06-11 20:28:06 +00002639 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002640
2641 This is controlled by the configure argument ``--with-universal-archs``:
2642
2643 - ``--with-universal-archs=all``: install 4-way universal
2644
2645 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2646
2647 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2648
2649 This option should be used in combination with ``--enable-universalsdk=``.
2650
2651 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Issue #1631171: Re-implement the 'warnings' module in C (the
2702 original Python code has been kept as backup). This will allow for
2703 using the 'warning's machinery in such places as the parser where
2704 use of pure Python code is not possible. Both the ``showarning()``
2705 and ``formatwarning()`` gain an optional 'line' argument which is
2706 not called by default for backwards-compatibility reasons. Setting
2707 ``warnings.showwarning()`` to an implementation that lacks support
2708 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002771- Issue #2550: The approach used by client/server code for obtaining
2772 ports to listen on in network-oriented tests has been refined in an
2773 effort to facilitate running multiple instances of the entire
2774 regression test suite in parallel without issue.
2775 test_support.bind_port() has been fixed such that it will always
2776 return a unique port -- which wasn't always the case with the
2777 previous implementation, especially if socket options had been set
2778 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2779 new implementation of bind_port() will actually raise an exception
2780 if it is passed an AF_INET/SOCK_STREAM socket with either the
2781 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2782 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2783 the socket it's been passed. This currently only applies to
2784 Windows. This option prevents any other sockets from binding to the
2785 host/port we've bound to, thus removing the possibility of the
2786 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2787 when a second SOCK_STREAM socket binds and accepts to a host/port
2788 that's already been bound by another socket. The optional preferred
2789 port parameter to bind_port() has been removed. Under no
2790 circumstances should tests be hard coding ports!
2791
2792 test_support.find_unused_port() has also been introduced, which will
2793 pass a temporary socket object to bind_port() in order to obtain an
2794 unused port. The temporary socket object is then closed and
2795 deleted, and the port is returned. This method should only be used
2796 for obtaining an unused port in order to pass to an external program
2797 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2798 a parameter to a server-oriented class that doesn't give you direct
2799 access to the underlying socket used.
2800
2801 Finally, test_support.HOST has been introduced, which should be used
2802 for the host argument of any relevant socket calls (i.e. bind and
2803 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002804
2805 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002806 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002807 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2808 test_asynchat and test_socket_ssl.
2809
Georg Brandl3ee81df2008-05-17 18:14:43 +00002810 It is now possible for multiple instances of the regression test
2811 suite to run in parallel without issue.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003087- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003088 issue 215555 for a discussion.
3089
Eric Smitha73fbe72008-02-23 03:09:44 +00003090- Added the future_builtins module, which contains hex() and oct().
3091 These are the PEP 3127 version of these functions, designed to be
3092 compatible with the hex() and oct() builtins from Python 3.0. They
3093 differ slightly in their output formats from the existing, unchanged
3094 Python 2.6 builtins. The expected usage of the future_builtins
3095 module is:
3096 from future_builtins import hex, oct
3097
Eric Smith7ef40bf2008-02-20 23:34:22 +00003098- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3099 exponents for exponents with absolute value < 100. Follows C99
3100 standard. This is a change on Windows, which would use 3 digits.
3101 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3102 so that any alterations it does to the resulting string will be
3103 available in stringlib/formatter.h (for float.__format__).
3104
Eric Smith5a3c1352008-02-19 13:21:56 +00003105- Implemented PEP 3101, Advanced String Formatting. This adds a new
3106 builtin format(); a format() method for str and unicode; a
3107 __format__() method to object, str, unicode, int, long, float, and
3108 datetime; the class string.Formatter; and the C API
3109 PyObject_Format().
3110
Georg Brandl3ee81df2008-05-17 18:14:43 +00003111- Fixed several potential crashes, all caused by specially crafted
3112 __del__ methods exploiting objects in temporarily inconsistent
3113 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003114
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003115- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116 prevent a possible crash: an Abstract Base Class would try to access
3117 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003118
Georg Brandl3ee81df2008-05-17 18:14:43 +00003119- Fixed repr() and str() of complex numbers with infinity or nan as
3120 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003121
Georg Brandl3ee81df2008-05-17 18:14:43 +00003122- Clear all free lists during a gc.collect() of the highest generation
3123 in order to allow pymalloc to free more arenas. Python may give back
3124 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003125
Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Issue #2045: Fix an infinite recursion triggered when printing a
3127 subclass of collections.defaultdict, if its default_factory is set
3128 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003129
Christian Heimesf75dbef2008-02-08 00:11:31 +00003130- Fixed a minor memory leak in dictobject.c. The content of the free
3131 list was not freed on interpreter shutdown.
3132
Georg Brandl3ee81df2008-05-17 18:14:43 +00003133- Limit free list of method and builtin function objects to 256
3134 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3137 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003138 to compact the internal free lists of pre-allocted ints and floats.
3139
Georg Brandl3ee81df2008-05-17 18:14:43 +00003140- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3141 calls. Python expected the return type int but the fork familie
3142 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003143
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3145 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003146
Georg Brandl3ee81df2008-05-17 18:14:43 +00003147- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3148 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003149
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3151 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003152
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3154 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003155
Georg Brandl3ee81df2008-05-17 18:14:43 +00003156- Patch #1473257: generator objects gain a gi_code attribute. This is
3157 the same object as the func_code attribute of the function that
3158 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003159
Georg Brandl3ee81df2008-05-17 18:14:43 +00003160- Issue #1920: "while 0" statements were completely removed by the
3161 compiler, even in the presence of an "else" clause, which is
3162 supposed to be run when the condition is false. Now the compiler
3163 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003164
Guido van Rossumeead05f2008-01-24 18:21:02 +00003165- A few crashers fixed: weakref_in_del.py (issue #1377858);
3166 loosing_dict_ref.py (issue #1303614, test67.py);
3167 borrowed_ref_[34].py (not in tracker).
3168
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003169- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003170 suppressed while an extension is loaded by calling SetErrorMode in
3171 dynload_win.c. The error is still reported properly.
3172
Georg Brandl3ee81df2008-05-17 18:14:43 +00003173- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003174 several extension methods and modules do not work without unicode
3175 support.
3176
Georg Brandl26543b12008-01-21 18:36:51 +00003177- Issue #1882: when compiling code from a string, encoding cookies in the
3178 second line of code were not always recognized correctly.
3179
Georg Brandl14404b62008-01-19 19:27:05 +00003180- Issue #1679: "0x" was taken as a valid integer literal.
3181
Georg Brandl6caad7d2008-01-26 14:19:22 +00003182- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003183 added.
3184
Christian Heimesc94e2b52008-01-14 04:13:37 +00003185- sys.float_info / PyFloat_GetInfo: The floating point information
3186 object was converted from a dict to a specialized structseq object.
3187
Georg Brandl3ee81df2008-05-17 18:14:43 +00003188- Patch #1816: Added sys.flags structseq. It exposes the status of
3189 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003190
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191- Objects/structseq.c: Implemented new structseq representation. The
3192 patch makes structseqs (e.g. the return value of os.stat) more
3193 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003194
Georg Brandl3ee81df2008-05-17 18:14:43 +00003195- Patch #1700288: added a type attribute cache that caches method
3196 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003197
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003198- Bug #1776: __import__() no longer accepts filenames on any platform.
3199 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003200
Georg Brandlaed6c662008-01-07 17:25:53 +00003201- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3202
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3204 envvar and sys.dont_write_bytecode attribute. All these can be set
3205 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003206
Georg Brandl3ee81df2008-05-17 18:14:43 +00003207- Improve some exception messages when Windows fails to load an
3208 extension module. Now we get for example '%1 is not a valid Win32
3209 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003210
Georg Brandl3ee81df2008-05-17 18:14:43 +00003211- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00003212
Georg Brandl3ee81df2008-05-17 18:14:43 +00003213- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3214 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003215
Christian Heimes0a8143f2007-12-18 23:22:54 +00003216- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003217 and INF. float("nan"), float("inf") and float("-inf") now work on
3218 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003219
Georg Brandl3ee81df2008-05-17 18:14:43 +00003220- Compiler now generates simpler and faster code for dictionary
3221 literals. The oparg for BUILD_MAP now indicates an estimated
3222 dictionary size. There is a new opcode, STORE_MAP, for adding
3223 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003224
Georg Brandl3ee81df2008-05-17 18:14:43 +00003225- Issue #1638: %zd configure test fails on Linux.

3253 file can now be directly executed by passing their name to the
3254 interpreter. The directory/zipfile is automatically inserted as the
3255 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003257- Issue #1265: Fix a problem with sys.settrace, if the tracing
3258 function uses a generator expression when at the same time the
3259 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003260
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003261- sets and frozensets now have an isdisjoint() method.
3262
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003263- optimize the performance of builtin.sum().
3264

3266
Georg Brandl3ee81df2008-05-17 18:14:43 +00003267- The enumerate() builtin function is no longer bounded to sequences
3268 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3269 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003270
Georg Brandl3ee81df2008-05-17 18:14:43 +00003271- Issue #1686386: Tuple's tp_repr did not take into account the
3272 possibility of having a self-referential tuple, which is possible
3273 from C code. Nor did object's tp_str consider that a type's tp_str
3274 could do something that could lead to an inifinite recursion.
3275 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3276 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003277
Georg Brandl3ee81df2008-05-17 18:14:43 +00003278- Issue #1164: It was possible to trigger deadlock when using the
3279 'print' statement to write to a file since the GIL was not released
3280 as needed. Now PyObject_Print() does the right thing along with
3281 various tp_print implementations of the built-in types and those in
3282 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Issue #1147: Exceptions were directly allowing string exceptions in
3285 their throw() method even though string exceptions no longer
3286 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003287
Georg Brandl3ee81df2008-05-17 18:14:43 +00003288- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003291- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003292 PyObject_Call() never calling back out to Python code to trigger
3293 recursion depth updates/checks. Required the creation of a static
3294 RuntimeError instance in case normalizing an exception put the
3295 recursion check value past its limit. Fixes crashers
3296 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003297
Georg Brandl3ee81df2008-05-17 18:14:43 +00003298- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003311- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003312 __*__ attributes. (Some already existed, e.g., __doc__ and
3313 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003314
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003315- Add -3 option to the interpreter to warn about features that are
3316 deprecated and will be changed/removed in Python 3.0.
3317
Georg Brandl2134e752007-05-21 20:34:16 +00003318- Patch #1686487: you can now pass any mapping after '**' in function
3319 calls.
3320
Collin Winter62903052007-05-18 23:11:24 +00003321- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003322 "except E as target:". This is to provide forwards compatibility
3323 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003324
Brett Cannon229cee22007-05-05 01:34:02 +00003325- Deprecate BaseException.message as per PEP 352.
3326
Georg Brandl3ee81df2008-05-17 18:14:43 +00003327- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003328 inherited from a builtin base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003330- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003331 setting a plain string, ie don't expand to single letter identifiers.

Raymond Hettinger13936692007-04-11 18:40:58 +00003333- Request #1191699: Slices can now be pickled.
3334
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003335- Request #1193128: str.translate() now allows a None argument for
3336 translations that only remove characters without re-mapping the
3337 remaining characters.
3338
Georg Brandl5cb76c12007-03-21 09:00:39 +00003339- Patch #1682205: a TypeError while unpacking an iterable is no longer
3340 masked by a generic one with the message "unpack non-sequence".

3343
Guido van Rossum143b5642007-03-23 04:58:42 +00003344- Bug #1683368: The object.__init__() and object.__new__() methods are
3345 now stricter in rejecting excess arguments. The only time when
3346 either allows excess arguments is when it is not overridden and the
3347 other one is. For backwards compatibility, when both are
3348 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003349 warning later). Also, type.__init__() insists on the same signature
3350 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003352- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3353 object to complex using its __complex__() method before falling back
3354 to the __float__() method. Therefore, the functions in the cmath
3355 module now can operate on objects that define a __complex__()
3356 method.

3373
Georg Brandl7b9c5552007-03-12 14:30:05 +00003374- Bug #1678647: write a newline after printing an exception in any
3375 case, even when converting the value to a string failed.
3376
Georg Brandl871f1bc2007-03-12 13:17:36 +00003377- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003378 its argument, if it exists. If not, it will work like before. This
3379 allows customizing the output of dir() in the presence of a
3380 __getattr__().

3390 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003391
Georg Brandlaa2321b2007-03-07 00:40:28 +00003392- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003393 makes the filenames the warning module prints much more sensible
3394 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003395

3408 sq_ass_slice instead of the sq_slice slot.
3409
Georg Brandl3ee81df2008-05-17 18:14:43 +00003410- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00003462- Bug #1545497: when given an explicit base, int() did ignore NULs
3463 embedded in the string to convert.
3464
Georg Brandl846f73a2006-10-08 07:11:54 +00003465- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003513 generator expressions (x for x, in ... ) works again. Fixing this
3514 problem required changing the .pyc magic number. This means that
3515 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003945 AttributeError instead of an IOError when the server's response
3946 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003947

3978
Georg Brandl92a6bae2007-03-13 17:43:32 +00003979- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003980 are set for invalid interpolation sequences that would lead to
3981 errors on reading back those values.

4035
Georg Brandl3ee81df2008-05-17 18:14:43 +00004036- unittest now verifies more of its assumptions. In particular,
4037 TestCase and TestSuite subclasses (not instances) are no longer
4038 accepted in TestSuite.addTest(). This should cause no
4039 incompatibility since it never made sense with ordinary subclasses
4040 -- the failure just occurred later, with a more cumbersome
4041 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004318- The implementation of UnicodeError objects has been simplified
4319 (start and end attributes are now stored directly as Py_ssize_t
4320 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004321
Georg Brandl3ee81df2008-05-17 18:14:43 +00004322- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4323 with RFC 3207 and forgets any knowledge obtained from the server not
4324 obtained from the TLS negotiation itself. Patch contributed by Bill
4325 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004326
Georg Brandl3ee81df2008-05-17 18:14:43 +00004327- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004328 that the SMTP.starttls() caller no longer needs to call ehlo()
4329 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004330 does not claim to support starttls. Adds the
4331 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4332 Fenner.

4412 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4413 silently miscode subclasses of those types. Now, it raises a
4414 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004415

Georg Brandl3ee81df2008-05-17 18:14:43 +00004430 time so that opening a database previously created with the DB_DUP
4431 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4432 opens. Specifically: dictionary assignment to a DB object will
4433 replace all values for a given key when the database allows
4434 duplicate values. DB users should use DB.put(k, v) when they want
4435 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004436

4442 characters with ASCII value less than 32. Also, it correctly quotes
4443 dots only if they occur on a single line, as opposed to the previous
4444 behavior of quoting dots if they are the second character of any
4445 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004446

Georg Brandl3ee81df2008-05-17 18:14:43 +00004851- Removed the macfs module. It had been deprecated since Python 2.5.
4852 This lead to the deprecation of macostools.touched() as it relied
4853 solely on macfs and was a no-op under OS X.
