138 statement and correctly lookup the __enter__ and __exit__ special methods.
139
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000140- Issue #5829: complex("1e500") no longer raises OverflowError. This
141 makes it consistent with float("1e500") and interpretation of real

152 (1) inf and nan strings with trailing whitespace were incorrectly
153 rejected; (2) parsing of strings representing infinities and nans
154 was locale aware; and (3) the interpretation of fromhex('-nan')
155 didn't match that of float('-nan').
156
Eric Smitha985a3a2009-05-05 18:26:08 +0000157- Issue #5920: For float.__format__, change the behavior with the
158 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
159 to be like 'g' but with at least one decimal point and with a
160 default precision of 12. Previously, the behavior the same but with
161 a default precision of 6. This more closely matches str(), and
162 reduces surprises when adding alignment flags to the empty
163 presentation type. This also affects the new complex.__format__ in
164 the same way.
165
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000166- Issue #5890: in subclasses of 'property' the __doc__ attribute was

175
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000176- Issue #5864: Fix empty format code formatting for floats so that it
177 never gives more than the requested number of significant digits.
178
Eric Smithcac7af62009-04-27 19:04:37 +0000179- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
180 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
181
Martin v. Löwis99f27792009-04-26 00:53:18 +0000182- Issue #4971: Fix titlecase for characters that are their own
183 titlecase, but not their own uppercase.
184
Eric Smith068f0652009-04-25 21:40:15 +0000185- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
186 _PyOS_double_to_string or PyOS_double_to_string.
187

189
Mark Dickinson95bc9802009-04-24 12:46:53 +0000190- Issue #5816: complex(repr(z)) now recovers z exactly, even when
191 z involves nans, infs or negative zeros.
192
Eric Smithaca19e62009-04-22 13:29:05 +0000193- Implement PEP 378, Format Specifier for Thousands Separator, for
194 floats, ints, and longs.
195
196- Issue #5515: 'n' formatting for ints, longs, and floats handles
197 leading zero formatting poorly.
198
199- Issue #5772: For float.__format__, don't add a trailing ".0" if
200 we're using no type code and we have an exponent.

206 some builtin types.
207
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000208- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000209 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000210
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000211- Issue #5759: float() didn't call __float__ on str subclasses.
212

229 untrackable objects are not tracked by the garbage collector. This can
230 reduce the size of collections and therefore the garbage collection overhead
231 on long-running programs, depending on their particular use of datatypes.
232
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000233- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
234 improve its performance. Long divisions and remainder operations
235 are now between 50% and 150% faster.
236
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000237- Issue #4258: Make it possible to use base 2**30 instead of base
238 2**15 for the internal representation of integers, for performance
239 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
240 --enable-big-digits option to configure, which overrides the
241 default. Add sys.long_info structseq to provide information about
242 the internal format.
243
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000244- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
245 result traceback.__members__ no longer exists.)
246
Mark Dickinson6b265f12009-03-18 16:07:26 +0000247- Issue #4474: PyUnicode_FromWideChar now converts characters outside
248 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

250
Eric Smith6f42edb2009-03-14 11:57:26 +0000251- Issue #5237: Allow auto-numbered fields in str.format(). For

253
Brett Cannon6c4cff02009-03-11 04:51:06 +0000254- Issue #3652: Make the 'line' argument for warnings.showwarning() a
255 requirement. Means the DeprecationWarning from Python 2.6 can go away.
256

265 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
266 on a 64-bit system.
267
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000268- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

273
Benjamin Petersone18ef192009-01-20 14:21:16 +0000274- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
275
Georg Brandl29c6a282009-04-05 20:23:13 +0000276- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000277 were suppressing all exceptions. These include list(), filter(), map(),
278 zip(), and bytearray().
279

306
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000307- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
308 an existing .py counterpart, override the co_filename attributes of all
309 code objects if the original filename is obsolete (which can happen if the
310 file has been renamed, moved, or if it is accessed through different paths).
311 Patch by Ziga Seilnacht and Jean-Paul Calderone.
312
Martin v. Löwis5344c992009-01-02 20:32:55 +0000313- Issue #4075: Use OutputDebugStringW in Py_FatalError.
314
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000315- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
316 file with `str' filename on Windows.
317
Antoine Pitrouaa687902009-01-01 14:11:22 +0000318- Issue #3680: Reference cycles created through a dict, set or deque iterator
319 did not get collected.
320
Nick Coghlan180e4002008-12-30 01:18:48 +0000321- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
322 where the tp_hash and tp_dict slots are both NULL.
323
Benjamin Peterson7af65562008-12-29 17:56:58 +0000324- Issue #4764: With io.open, IOError.filename is set when trying to open a
325 directory on POSIX systems.
326
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000327- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
328 systems.
329
Georg Brandl6425a2f2008-12-28 11:54:53 +0000330- Issue #4759: None is now allowed as the first argument of
331 bytearray.translate(). It was always allowed for bytes.translate().
332
Skip Montanarof205c132008-12-23 03:30:15 +0000333- Added test case to ensure attempts to read from a file opened for writing
334 fail.
335
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000336- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
337 print elapsed times, not only when some objects are uncollectable /
338 unreachable. Original patch by Neil Schemenauer.
339

346 context manager returns a value that cannot be converted to a bool.
347
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000348- Issue #4597: Fixed several opcodes that weren't always propagating
349 exceptions.
350
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000351- Issue #4445: Replace "sizeof(PyStringObject)" with
352 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
353 str instances. On a typical machine this saves 3 bytes of memory
354 (on average) per string allocation.
355
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000356- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
357 interpreter to abort ("Fatal Python error: Could not reset the stack!")
358 instead of throwing a MemoryError.
359
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000360- Issue #3689: The list reversed iterator now supports __length_hint__

364 module couldn't be imported and \N escapes were present.
365
Vinay Sajip213faca2008-12-03 23:22:58 +0000366- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000367 method on file objects with closefd=False. The file descriptor is still
368 kept open but the file object behaves like a closed file. The ``FileIO``
369 object also got a new readonly attribute ``closefd``.
370
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000371- Issue #4348: Some bytearray methods returned that didn't cause any change to
372 the bytearray, returned the same bytearray instead of a copy.
373
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000374- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

381 exec statement.
382
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000383- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
384 method does not return iterators for the 4th and 5th items.
385
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000386- Issue #4209: Enabling unicode_literals and the print_function in the same
387 __future__ import didn't work.
388
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000389- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000390 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000391
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000392- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
393 returned a path longer than MAX_PATH. (But It's doubtful this code path is
394 really executed because I cannot move to such directory on win2k)
395
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000396- Issue #4069: When set.remove(element) is used with a set element, the element
397 is temporarily replaced with an equivalent frozenset. But the eventual
398 KeyError would always report the empty frozenset([]) as the missing key. Now
399 it correctly refers to the initial element.
400
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000401- Issue #4509: Various issues surrounding resize of bytearray objects to
402 which there are buffer exports.
403

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000416- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
417 returned them on 64bit platforms.
418
Walter Dörwalded960ac2009-05-03 22:36:33 +0000419- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
420 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
421 step. This avoids problems with counting UTF-8 bytes that ignores the effect
422 of using the replace error handler in PyUnicode_DecodeUTF8().
423
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000424- Issue #3739: The unicode-internal encoder now reports the number of characters
425 consumed like any other encoder (instead of the number of bytes).

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001649- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1650 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1651 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1652 ``printf`` function, whereas PyString_FromFormat has an independent
1653 implementation and uses "%zd" on all platforms for size_t values.
1654 This makes a difference on win64, where ``printf`` needs "%Id" to display
1655 64bit values.

1661 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001672 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001674- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001675 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1676 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1677 when given a tuple of classes as second argument, were looking up
1678 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1679 type object.

1750 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1751 for catch_warnings() also led to an improvement in the raising of a
1752 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001818What's New in Python 2.6 beta 3?
1819================================
1820
Barry Warsaw07a4a382008-08-21 01:15:08 +00001821*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001822
1823Core and Builtins
1824-----------------
1825
Guido van Rossumf8402962008-08-20 15:01:50 +00001826- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1827 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1828 extensions do not automatically benefit from the class attribute
1829 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1830 to their tp_flags field if they care. This is a backwards
1831 compatibility feature; in 3.0, all types will use the cache by
1832 default.
1833
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001834- Keyword arguments can now follow starred arguments. (``f(a, *args,
1835 keyword=23)`` is now valid syntax.)
1836
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001837- ctypes function pointers that are COM methods have a boolean True
1838 value again.
1839
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001840- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1841 by denying s# to parse objects that have a releasebuffer procedure,
1842 and introducing s*.
1843
Georg Brandl1e13ea92008-08-11 09:07:59 +00001844- Issue #3537: Fix an assertion failure when an empty but presized dict
1845 object was stored in the freelist.
1846
Mark Dickinsonb6467572008-08-04 21:30:09 +00001847- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1848 ValueError consistently across platforms.
1849
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001850- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1851 (64bit Unix, for example), unichr() would truncate its argument and return
1852 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1853
Neal Norwitze7d8be82008-07-31 17:17:14 +00001854- Apply security patches from Apple.
1855
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001856- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1857 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1858
Antoine Pitrou92f82162008-07-25 22:22:08 +00001859- Issue #1819: function calls with several named parameters are now on
1860 average 35% faster (as measured by pybench).
1861
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001862- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1863 the python debugger steps into a class statement: the free variables (local
1864 variables defined in an outer scope) would be deleted from the outer scope.
1865
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001866- Issue #2620: Overflow checking when allocating or reallocating memory
1867 was not always being done properly in some python types and extension
1868 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1869 all been updated to perform better checks and places in the code that
1870 would previously leak memory on the error path when such an allocation
1871 failed have been fixed.

1875
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001876- Issue #3612: Added some missing basic types in ctypes.wintypes.
1877
Benjamin Petersone977ad42008-08-20 01:42:01 +00001878- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1879 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1880
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001881- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1882 version reported by these tools does not necessarily follow the python
1883 version numbering scheme, so the module is less strict when parsing it.
1884
Nick Coghlanf70385a2008-08-18 12:42:46 +00001885- Issue #2235: Added Py3k warnings for types which will become unhashable
1886 under the stricter __hash__ inheritance rules in 3.0. Several types
1887 which did not meet the rules for hash invariants and were already
1888 unhashable in 3.0 have now been explicitly flagged as unhashable in
1889 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1890 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1891
Brett Cannon88f801d2008-08-18 00:46:22 +00001892- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1893 imported into the module but exposed as part of the module's API.
1894
Brett Cannon7b96f072008-08-18 00:41:11 +00001895- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1896
Brett Cannon46225e72008-08-18 00:36:52 +00001897- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1900
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001901- Issue #3575: Incremental decoder's decode function now takes bytearray
1902 by using 's*' instead of 't#'.
1903
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001904- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001905 fails unicode conversion on 2nd parameter. (windows only)
1906
Facundo Batista94f243a2008-08-17 03:38:39 +00001907- Issue 2464. urllib2 now supports a malformation in the URL received
1908 in a redirect.
1909
Brett Cannonabe423e2008-08-16 21:47:07 +00001910- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001911 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001912
Facundo Batistaeb90b782008-08-16 14:44:07 +00001913- Issue #2776: fixed small issue when handling an URL with double slash
1914 after a 302 response in the case of not going through a proxy.
1915
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001916- Issue #2676: in the email package, content-type parsing was hanging on
1917 pathological input because of quadratic or exponential behaviour of a
1918 regular expression.
1919
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001920- Issue #3476: binary buffered reading through the new "io" library is now
1921 thread-safe.
1922
Brett Cannonbf3157b2008-08-14 05:00:03 +00001923- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1924 since mimetools itself is deprecated. Because modules are cached, all
1925 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1926
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001927- Issue #3134: shutil referenced undefined WindowsError symbol.
1928
Robert Schuppenies14646332008-08-10 11:01:53 +00001929- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1930 menu entries were not deleted.
1931
Brett Cannon83e81842008-08-09 23:30:55 +00001932- Copied the implementation of reduce() to _functools.reduce() to have a
1933 version that did not raise a DeprecationWarning under -3.
1934
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001935- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1936 a MemoryError rather than silently stop the iteration.
1937
Guido van Rossum59ce9012008-08-09 14:55:34 +00001938- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1939 to _sre.compile() will now be rejected. This should not affect anybody
1940 since the re.compile() function never generates invalid re-bytecode.
1941
Skip Montanaroa032bf42008-08-08 22:52:51 +00001942- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1943 upon first access it can be automatically initialized from the csv file if
1944 it wasn't initialized during instantiation.

Antoine Pitroude781a42008-08-09 12:43:23 +00001961 asking for a specific length. This problem only affected files opened
1962 using the new "io" module, not the built-in open() function.

2018-----------------
2019
Georg Brandl3e483f62008-07-16 22:57:41 +00002020- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2021 its methods now allow for items objects that can be converted to
2022 an integer using operator.index().
2023
Mark Dickinson64b7e502008-07-16 09:40:03 +00002024- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2025 produced a ValueError instead of giving the correct float.
2026
Eric Smitha5fa5a22008-07-16 00:11:49 +00002027- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2028 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2029
Mark Dickinson7103aa42008-07-15 19:08:33 +00002030- Issue #3008: the float type has a new instance method 'float.hex'
2031 and a new class method 'float.fromhex' to convert floating-point
2032 numbers to and from hexadecimal strings, respectively.
2033
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002034- Issue #2235: __hash__ is once again inherited by default. To allow
2035 collections.Hashable to remain meaningful in the presence of the
2036 default hash implementation (object.__hash__), it is now possible
2037 to explicit block inheritance of hash by setting __hash__=None at
2038 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2039 level.
2040
Nick Coghlanb028f502008-07-13 14:52:36 +00002041- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2042 the parent module cannot be found while performing an absolute import.
2043 This means that an incorrectly defined __package__ attribute will
2044 now only prevent relative imports in that module rather than causing
2045 all imports from that module to fail.
2046
Nick Coghlan14ff9942008-07-08 14:21:42 +00002047- Issue #2517: Allow unicode messages in Exceptions again by correctly

2052 set to a custom object whose write() method happens to install
2053 another file in sys.stdout.
2054
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002055- Issue #3088: Corrected a race condition in classes derived from
2056 threading.local: the first member set by a thread could be saved in
2057 another thread's dictionary.
2058
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002059- Issue #3004: Minor change to slice.indices(): the start and stop
2060 arguments are now treated identically, making the behaviour easier
2061 to describe and understand. For example, slice(None, -10,
2062 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2063 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2064 10, -1).
2065
Georg Brandl278fc502008-07-19 12:46:12 +00002066- Issue #3219: Calling a function with repeated keyword arguments,
2067 f(a=2, a=23), would not cause a syntax error. This was a regression
2068 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002069
Georg Brandl278fc502008-07-19 12:46:12 +00002070- Issue #2862: Make int and float freelist management consistent with
2071 other freelists. Changes their CompactFreeList apis into
2072 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002077- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2078 api functions without holding the GIL, which could lead to a fatal
2079 error when they failed.
2080
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002081- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2091
Vinay Sajip51e65192008-07-18 09:01:10 +00002092- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002106- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2107 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002108 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002109 content-length. The problem had been corrected in the 2.4 branch, but never
2110 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002125- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2126 handling is now the same as that of other special attributes like __name__).

2584 and ``formatwarning()`` gain an optional 'line' argument which is
2585 not called by default for backwards-compatibility reasons. Setting
2586 ``warnings.showwarning()`` to an implementation that lacks support
2587 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002650- Issue #2550: The approach used by client/server code for obtaining
2651 ports to listen on in network-oriented tests has been refined in an
2652 effort to facilitate running multiple instances of the entire
2653 regression test suite in parallel without issue.
2654 test_support.bind_port() has been fixed such that it will always
2655 return a unique port -- which wasn't always the case with the
2656 previous implementation, especially if socket options had been set
2657 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2658 new implementation of bind_port() will actually raise an exception
2659 if it is passed an AF_INET/SOCK_STREAM socket with either the
2660 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2661 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2662 the socket it's been passed. This currently only applies to
2663 Windows. This option prevents any other sockets from binding to the
2664 host/port we've bound to, thus removing the possibility of the
2665 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2666 when a second SOCK_STREAM socket binds and accepts to a host/port
2667 that's already been bound by another socket. The optional preferred
2668 port parameter to bind_port() has been removed. Under no
2669 circumstances should tests be hard coding ports!
2670
2671 test_support.find_unused_port() has also been introduced, which will
2672 pass a temporary socket object to bind_port() in order to obtain an
2673 unused port. The temporary socket object is then closed and
2674 deleted, and the port is returned. This method should only be used
2675 for obtaining an unused port in order to pass to an external program
2676 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2677 a parameter to a server-oriented class that doesn't give you direct
2678 access to the underlying socket used.
2679
2680 Finally, test_support.HOST has been introduced, which should be used
2681 for the host argument of any relevant socket calls (i.e. bind and
2682 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002683
2684 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002685 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

2687 test_asynchat and test_socket_ssl.
2688
Georg Brandl3ee81df2008-05-17 18:14:43 +00002689 It is now possible for multiple instances of the regression test
2690 suite to run in parallel without issue.

2957-----------------
2958
Fred Drakea8ee94b2008-03-01 02:45:07 +00002959- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002960 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002965
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002966- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002967 issue 215555 for a discussion.
2968
Eric Smitha73fbe72008-02-23 03:09:44 +00002969- Added the future_builtins module, which contains hex() and oct().
2970 These are the PEP 3127 version of these functions, designed to be
2971 compatible with the hex() and oct() builtins from Python 3.0. They
2972 differ slightly in their output formats from the existing, unchanged
2973 Python 2.6 builtins. The expected usage of the future_builtins
2974 module is:
2975 from future_builtins import hex, oct
2976
Eric Smith7ef40bf2008-02-20 23:34:22 +00002977- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2978 exponents for exponents with absolute value < 100. Follows C99
2979 standard. This is a change on Windows, which would use 3 digits.
2980 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2981 so that any alterations it does to the resulting string will be
2982 available in stringlib/formatter.h (for float.__format__).
2983
Eric Smith5a3c1352008-02-19 13:21:56 +00002984- Implemented PEP 3101, Advanced String Formatting. This adds a new
2985 builtin format(); a format() method for str and unicode; a
2986 __format__() method to object, str, unicode, int, long, float, and
2987 datetime; the class string.Formatter; and the C API
2988 PyObject_Format().
2989
Georg Brandl3ee81df2008-05-17 18:14:43 +00002990- Fixed several potential crashes, all caused by specially crafted
2991 __del__ methods exploiting objects in temporarily inconsistent
2992 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002993
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002994- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002995 prevent a possible crash: an Abstract Base Class would try to access
2996 a slot on a registered virtual subclass.

3003 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003004
Georg Brandl3ee81df2008-05-17 18:14:43 +00003005- Issue #2045: Fix an infinite recursion triggered when printing a
3006 subclass of collections.defaultdict, if its default_factory is set
3007 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003008
Christian Heimesf75dbef2008-02-08 00:11:31 +00003009- Fixed a minor memory leak in dictobject.c. The content of the free
3010 list was not freed on interpreter shutdown.
3011
Georg Brandl3ee81df2008-05-17 18:14:43 +00003012- Limit free list of method and builtin function objects to 256

Georg Brandl3ee81df2008-05-17 18:14:43 +00003015- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3016 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003017 to compact the internal free lists of pre-allocted ints and floats.
3018
Georg Brandl3ee81df2008-05-17 18:14:43 +00003019- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3020 calls. Python expected the return type int but the fork familie
3021 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003022

Georg Brandl3ee81df2008-05-17 18:14:43 +00003035- Patch #1473257: generator objects gain a gi_code attribute. This is
3036 the same object as the func_code attribute of the function that
3037 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003038
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039- Issue #1920: "while 0" statements were completely removed by the
3040 compiler, even in the presence of an "else" clause, which is
3041 supposed to be run when the condition is false. Now the compiler
3042 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003043

Georg Brandl3ee81df2008-05-17 18:14:43 +00003070- Objects/structseq.c: Implemented new structseq representation. The
3071 patch makes structseqs (e.g. the return value of os.stat) more
3072 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003073
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- Patch #1700288: added a type attribute cache that caches method
3075 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003076
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003077- Bug #1776: __import__() no longer accepts filenames on any platform.

3081
Georg Brandl3ee81df2008-05-17 18:14:43 +00003082- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3083 envvar and sys.dont_write_bytecode attribute. All these can be set
3084 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003086- Improve some exception messages when Windows fails to load an
3087 extension module. Now we get for example '%1 is not a valid Win32
3088 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003089

Georg Brandl3ee81df2008-05-17 18:14:43 +00003096 and INF. float("nan"), float("inf") and float("-inf") now work on
3097 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003099- Compiler now generates simpler and faster code for dictionary
3100 literals. The oparg for BUILD_MAP now indicates an estimated
3101 dictionary size. There is a new opcode, STORE_MAP, for adding
3102 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003131- Patch #1739468: Directories and zipfiles containing a __main__.py
3132 file can now be directly executed by passing their name to the
3133 interpreter. The directory/zipfile is automatically inserted as the
3134 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Issue #1265: Fix a problem with sys.settrace, if the tracing
3137 function uses a generator expression when at the same time the
3138 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003139
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003140- sets and frozensets now have an isdisjoint() method.

3145
Georg Brandl3ee81df2008-05-17 18:14:43 +00003146- The enumerate() builtin function is no longer bounded to sequences
3147 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3148 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003149
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Issue #1686386: Tuple's tp_repr did not take into account the
3151 possibility of having a self-referential tuple, which is possible
3152 from C code. Nor did object's tp_str consider that a type's tp_str
3153 could do something that could lead to an inifinite recursion.
3154 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3155 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003156
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157- Issue #1164: It was possible to trigger deadlock when using the
3158 'print' statement to write to a file since the GIL was not released
3159 as needed. Now PyObject_Print() does the right thing along with
3160 various tp_print implementations of the built-in types and those in
3161 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003162
Georg Brandl3ee81df2008-05-17 18:14:43 +00003163- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00003169
Brett Cannon1e534b52007-09-07 04:18:30 +00003170- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171 PyObject_Call() never calling back out to Python code to trigger
3172 recursion depth updates/checks. Required the creation of a static
3173 RuntimeError instance in case normalizing an exception put the
3174 recursion check value past its limit. Fixes crashers
3175 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003190- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191 __*__ attributes. (Some already existed, e.g., __doc__ and
3192 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003193
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003194- Add -3 option to the interpreter to warn about features that are

3196
Georg Brandl2134e752007-05-21 20:34:16 +00003197- Patch #1686487: you can now pass any mapping after '**' in function
3198 calls.
3199
Collin Winter62903052007-05-18 23:11:24 +00003200- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003201 "except E as target:". This is to provide forwards compatibility
3202 with Python 3.0.

3208
Vinay Sajip8549ce32007-05-06 17:53:37 +00003209- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003210 setting a plain string, ie don't expand to single letter identifiers.
3211
Raymond Hettinger13936692007-04-11 18:40:58 +00003212- Request #1191699: Slices can now be pickled.
3213
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003214- Request #1193128: str.translate() now allows a None argument for

3216 remaining characters.
3217
Georg Brandl5cb76c12007-03-21 09:00:39 +00003218- Patch #1682205: a TypeError while unpacking an iterable is no longer

3220
Neal Norwitzaa754b72007-03-21 06:39:48 +00003221- Remove unused file Python/fmod.c.
3222
Guido van Rossum143b5642007-03-23 04:58:42 +00003223- Bug #1683368: The object.__init__() and object.__new__() methods are
3224 now stricter in rejecting excess arguments. The only time when
3225 either allows excess arguments is when it is not overridden and the
3226 other one is. For backwards compatibility, when both are
3227 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003228 warning later). Also, type.__init__() insists on the same signature
3229 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003230
Georg Brandl3ee81df2008-05-17 18:14:43 +00003231- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3232 object to complex using its __complex__() method before falling back
3233 to the __float__() method. Therefore, the functions in the cmath
3234 module now can operate on objects that define a __complex__()
3235 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003236
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237- Patch #1623563: allow __class__ assignment for classes with
3238 __slots__. The old and the new class are still required to have the
3239 same slot names.

3252
Georg Brandl7b9c5552007-03-12 14:30:05 +00003253- Bug #1678647: write a newline after printing an exception in any
3254 case, even when converting the value to a string failed.
3255
Georg Brandl871f1bc2007-03-12 13:17:36 +00003256- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003257 its argument, if it exists. If not, it will work like before. This
3258 allows customizing the output of dir() in the presence of a
3259 __getattr__().

3268 parthensized forms. This means complex(repr(x)) now works instead of
3269 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003270
Georg Brandlaa2321b2007-03-07 00:40:28 +00003271- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003272 makes the filenames the warning module prints much more sensible
3273 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003274

Georg Brandl0fca97a2007-03-05 22:28:08 +00003286- Patch #1674228: when assigning a slice (old-style), check for the
3287 sq_ass_slice instead of the sq_slice slot.
3288
Georg Brandl3ee81df2008-05-17 18:14:43 +00003289- When printing an unraisable error, don't print exceptions. before
3290 the name. This duplicates the behavior whening normally printing
3291 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003824 AttributeError instead of an IOError when the server's response
3825 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003826

Georg Brandl3ee81df2008-05-17 18:14:43 +00003831- Patch #1429539: pdb now correctly initializes the __main__ module
3832 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003833 correctly now.
3834

3841
Georg Brandl3ee81df2008-05-17 18:14:43 +00003842- Patch #1530482: add pydoc.render_doc() which returns the

3857
Georg Brandl92a6bae2007-03-13 17:43:32 +00003858- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003859 are set for invalid interpolation sequences that would lead to
3860 errors on reading back those values.

Collin Winter22c42ba2007-03-10 02:51:26 +00003895

3901

3903 returned string up to the first NUL character.
3904

3914
Georg Brandl3ee81df2008-05-17 18:14:43 +00003915- unittest now verifies more of its assumptions. In particular,
3916 TestCase and TestSuite subclasses (not instances) are no longer
3917 accepted in TestSuite.addTest(). This should cause no
3918 incompatibility since it never made sense with ordinary subclasses
3919 -- the failure just occurred later, with a more cumbersome
3920 exception.

4280 contents before adding elements from the iterable. This fix brings
4281 the behavior into line with that for list.__init__().

4291 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4292 silently miscode subclasses of those types. Now, it raises a
4293 ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004308- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004309 time so that opening a database previously created with the DB_DUP
4310 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4311 opens. Specifically: dictionary assignment to a DB object will
4312 replace all values for a given key when the database allows
4313 duplicate values. DB users should use DB.put(k, v) when they want
4314 to store duplicates; not DB[k] = v.

4321 characters with ASCII value less than 32. Also, it correctly quotes
4322 dots only if they occur on a single line, as opposed to the previous
4323 behavior of quoting dots if they are the second character of any
4324 line.

4670 of w# format code incorrectly truncated the length to an int, even
4671 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4672 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004702- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4703 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
