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

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

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

414 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000415
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).

1645
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001646- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1647 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1648 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1649 ``printf`` function, whereas PyString_FromFormat has an independent
1650 implementation and uses "%zd" on all platforms for size_t values.
1651 This makes a difference on win64, where ``printf`` needs "%Id" to display
1652 64bit values.

1658 object; previously an int would be returned for small values. the __long__
1659 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001669 was correctly parsed but parsing of subsequent arguments failed.
1670
Vinay Sajip35e3b032008-09-01 14:33:59 +00001671- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001672 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1673 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1674 when given a tuple of classes as second argument, were looking up
1675 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1676 type object.

1747 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1748 for catch_warnings() also led to an improvement in the raising of a
1749 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001815What's New in Python 2.6 beta 3?
1816================================
1817
Barry Warsaw07a4a382008-08-21 01:15:08 +00001818*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001819
1820Core and Builtins
1821-----------------
1822
Guido van Rossumf8402962008-08-20 15:01:50 +00001823- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1824 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1825 extensions do not automatically benefit from the class attribute
1826 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1827 to their tp_flags field if they care. This is a backwards
1828 compatibility feature; in 3.0, all types will use the cache by
1829 default.
1830
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001831- Keyword arguments can now follow starred arguments. (``f(a, *args,
1832 keyword=23)`` is now valid syntax.)
1833
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001834- ctypes function pointers that are COM methods have a boolean True
1835 value again.
1836
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001837- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1838 by denying s# to parse objects that have a releasebuffer procedure,
1839 and introducing s*.
1840
Georg Brandl1e13ea92008-08-11 09:07:59 +00001841- Issue #3537: Fix an assertion failure when an empty but presized dict
1842 object was stored in the freelist.
1843
Mark Dickinsonb6467572008-08-04 21:30:09 +00001844- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1845 ValueError consistently across platforms.
1846
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001847- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1848 (64bit Unix, for example), unichr() would truncate its argument and return
1849 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1850
Neal Norwitze7d8be82008-07-31 17:17:14 +00001851- Apply security patches from Apple.
1852
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001853- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1854 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1855
Antoine Pitrou92f82162008-07-25 22:22:08 +00001856- Issue #1819: function calls with several named parameters are now on
1857 average 35% faster (as measured by pybench).
1858
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001859- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1860 the python debugger steps into a class statement: the free variables (local
1861 variables defined in an outer scope) would be deleted from the outer scope.
1862
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001863- Issue #2620: Overflow checking when allocating or reallocating memory
1864 was not always being done properly in some python types and extension
1865 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1866 all been updated to perform better checks and places in the code that
1867 would previously leak memory on the error path when such an allocation
1868 failed have been fixed.

1872
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001873- Issue #3612: Added some missing basic types in ctypes.wintypes.
1874
Benjamin Petersone977ad42008-08-20 01:42:01 +00001875- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1876 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1877
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001878- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1879 version reported by these tools does not necessarily follow the python
1880 version numbering scheme, so the module is less strict when parsing it.
1881
Nick Coghlanf70385a2008-08-18 12:42:46 +00001882- Issue #2235: Added Py3k warnings for types which will become unhashable
1883 under the stricter __hash__ inheritance rules in 3.0. Several types
1884 which did not meet the rules for hash invariants and were already
1885 unhashable in 3.0 have now been explicitly flagged as unhashable in
1886 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1887 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1888
Brett Cannon88f801d2008-08-18 00:46:22 +00001889- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1890 imported into the module but exposed as part of the module's API.
1891
Brett Cannon7b96f072008-08-18 00:41:11 +00001892- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1893
Brett Cannon46225e72008-08-18 00:36:52 +00001894- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001896- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1897
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001898- Issue #3575: Incremental decoder's decode function now takes bytearray
1899 by using 's*' instead of 't#'.
1900
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001901- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001902 fails unicode conversion on 2nd parameter. (windows only)
1903
Facundo Batista94f243a2008-08-17 03:38:39 +00001904- Issue 2464. urllib2 now supports a malformation in the URL received
1905 in a redirect.
1906
Brett Cannonabe423e2008-08-16 21:47:07 +00001907- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001908 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001909
Facundo Batistaeb90b782008-08-16 14:44:07 +00001910- Issue #2776: fixed small issue when handling an URL with double slash
1911 after a 302 response in the case of not going through a proxy.
1912
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001913- Issue #2676: in the email package, content-type parsing was hanging on
1914 pathological input because of quadratic or exponential behaviour of a
1915 regular expression.
1916
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001917- Issue #3476: binary buffered reading through the new "io" library is now
1918 thread-safe.
1919
Brett Cannonbf3157b2008-08-14 05:00:03 +00001920- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1921 since mimetools itself is deprecated. Because modules are cached, all
1922 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1923
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001924- Issue #3134: shutil referenced undefined WindowsError symbol.
1925
Robert Schuppenies14646332008-08-10 11:01:53 +00001926- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1927 menu entries were not deleted.
1928
Brett Cannon83e81842008-08-09 23:30:55 +00001929- Copied the implementation of reduce() to _functools.reduce() to have a
1930 version that did not raise a DeprecationWarning under -3.
1931
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001932- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1933 a MemoryError rather than silently stop the iteration.
1934
Guido van Rossum59ce9012008-08-09 14:55:34 +00001935- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1936 to _sre.compile() will now be rejected. This should not affect anybody
1937 since the re.compile() function never generates invalid re-bytecode.
1938
Skip Montanaroa032bf42008-08-08 22:52:51 +00001939- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00001958 asking for a specific length. This problem only affected files opened
1959 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001960

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002014Core and Builtins
2015-----------------
2016
Georg Brandl3e483f62008-07-16 22:57:41 +00002017- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2018 its methods now allow for items objects that can be converted to
2019 an integer using operator.index().
2020
Mark Dickinson64b7e502008-07-16 09:40:03 +00002021- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2022 produced a ValueError instead of giving the correct float.
2023
Eric Smitha5fa5a22008-07-16 00:11:49 +00002024- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2025 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2026
Mark Dickinson7103aa42008-07-15 19:08:33 +00002027- Issue #3008: the float type has a new instance method 'float.hex'
2028 and a new class method 'float.fromhex' to convert floating-point
2029 numbers to and from hexadecimal strings, respectively.
2030
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002031- Issue #2235: __hash__ is once again inherited by default. To allow
2032 collections.Hashable to remain meaningful in the presence of the
2033 default hash implementation (object.__hash__), it is now possible
2034 to explicit block inheritance of hash by setting __hash__=None at
2035 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2036 level.
2037
Nick Coghlanb028f502008-07-13 14:52:36 +00002038- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2039 the parent module cannot be found while performing an absolute import.
2040 This means that an incorrectly defined __package__ attribute will
2041 now only prevent relative imports in that module rather than causing
2042 all imports from that module to fail.
2043
Nick Coghlan14ff9942008-07-08 14:21:42 +00002044- Issue #2517: Allow unicode messages in Exceptions again by correctly
2045 bypassing the instance dictionary when looking up __unicode__ on
2046 new-style classes.

2049 set to a custom object whose write() method happens to install
2050 another file in sys.stdout.
2051
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002052- Issue #3088: Corrected a race condition in classes derived from
2053 threading.local: the first member set by a thread could be saved in
2054 another thread's dictionary.
2055
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002056- Issue #3004: Minor change to slice.indices(): the start and stop
2057 arguments are now treated identically, making the behaviour easier
2058 to describe and understand. For example, slice(None, -10,
2059 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2060 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2061 10, -1).
2062
Georg Brandl278fc502008-07-19 12:46:12 +00002063- Issue #3219: Calling a function with repeated keyword arguments,
2064 f(a=2, a=23), would not cause a syntax error. This was a regression
2065 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002066
Georg Brandl278fc502008-07-19 12:46:12 +00002067- Issue #2862: Make int and float freelist management consistent with
2068 other freelists. Changes their CompactFreeList apis into
2069 ClearFreeList apis and calls them via gc.collect().

2073
Thomas Heller57adf222008-08-14 19:10:48 +00002074- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2075 api functions without holding the GIL, which could lead to a fatal
2076 error when they failed.
2077
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002078- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2087 ForkingPickler.register() to resolve conflict with ctypes.
2088
Vinay Sajip51e65192008-07-18 09:01:10 +00002089- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002090

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002102
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002103- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2104 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002105 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002106 content-length. The problem had been corrected in the 2.4 branch, but never
2107 merged into trunk.
2108
Georg Brandle78fbcc2008-07-05 10:13:36 +00002109- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002122- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2123 handling is now the same as that of other special attributes like __name__).
2124
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002125- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

2581 and ``formatwarning()`` gain an optional 'line' argument which is
2582 not called by default for backwards-compatibility reasons. Setting
2583 ``warnings.showwarning()`` to an implementation that lacks support
2584 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002647- Issue #2550: The approach used by client/server code for obtaining
2648 ports to listen on in network-oriented tests has been refined in an
2649 effort to facilitate running multiple instances of the entire
2650 regression test suite in parallel without issue.
2651 test_support.bind_port() has been fixed such that it will always
2652 return a unique port -- which wasn't always the case with the
2653 previous implementation, especially if socket options had been set
2654 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2655 new implementation of bind_port() will actually raise an exception
2656 if it is passed an AF_INET/SOCK_STREAM socket with either the
2657 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2658 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2659 the socket it's been passed. This currently only applies to
2660 Windows. This option prevents any other sockets from binding to the
2661 host/port we've bound to, thus removing the possibility of the
2662 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2663 when a second SOCK_STREAM socket binds and accepts to a host/port
2664 that's already been bound by another socket. The optional preferred
2665 port parameter to bind_port() has been removed. Under no
2666 circumstances should tests be hard coding ports!
2667
2668 test_support.find_unused_port() has also been introduced, which will
2669 pass a temporary socket object to bind_port() in order to obtain an
2670 unused port. The temporary socket object is then closed and
2671 deleted, and the port is returned. This method should only be used
2672 for obtaining an unused port in order to pass to an external program
2673 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2674 a parameter to a server-oriented class that doesn't give you direct
2675 access to the underlying socket used.
2676
2677 Finally, test_support.HOST has been introduced, which should be used
2678 for the host argument of any relevant socket calls (i.e. bind and
2679 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002680
2681 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002682 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002683 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2684 test_asynchat and test_socket_ssl.
2685
Georg Brandl3ee81df2008-05-17 18:14:43 +00002686 It is now possible for multiple instances of the regression test
2687 suite to run in parallel without issue.

2954-----------------
2955
Fred Drakea8ee94b2008-03-01 02:45:07 +00002956- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002957 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002962
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002963- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002964 issue 215555 for a discussion.
2965
Eric Smitha73fbe72008-02-23 03:09:44 +00002966- Added the future_builtins module, which contains hex() and oct().
2967 These are the PEP 3127 version of these functions, designed to be
2968 compatible with the hex() and oct() builtins from Python 3.0. They
2969 differ slightly in their output formats from the existing, unchanged
2970 Python 2.6 builtins. The expected usage of the future_builtins
2971 module is:
2972 from future_builtins import hex, oct
2973
Eric Smith7ef40bf2008-02-20 23:34:22 +00002974- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2975 exponents for exponents with absolute value < 100. Follows C99
2976 standard. This is a change on Windows, which would use 3 digits.
2977 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2978 so that any alterations it does to the resulting string will be
2979 available in stringlib/formatter.h (for float.__format__).
2980
Eric Smith5a3c1352008-02-19 13:21:56 +00002981- Implemented PEP 3101, Advanced String Formatting. This adds a new
2982 builtin format(); a format() method for str and unicode; a
2983 __format__() method to object, str, unicode, int, long, float, and
2984 datetime; the class string.Formatter; and the C API
2985 PyObject_Format().
2986
Georg Brandl3ee81df2008-05-17 18:14:43 +00002987- Fixed several potential crashes, all caused by specially crafted
2988 __del__ methods exploiting objects in temporarily inconsistent
2989 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002990
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002991- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002992 prevent a possible crash: an Abstract Base Class would try to access
2993 a slot on a registered virtual subclass.

2999 in order to allow pymalloc to free more arenas. Python may give back
3000 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003001
Georg Brandl3ee81df2008-05-17 18:14:43 +00003002- Issue #2045: Fix an infinite recursion triggered when printing a

Christian Heimesf75dbef2008-02-08 00:11:31 +00003006- Fixed a minor memory leak in dictobject.c. The content of the free
3007 list was not freed on interpreter shutdown.
3008
Georg Brandl3ee81df2008-05-17 18:14:43 +00003009- Limit free list of method and builtin function objects to 256

Georg Brandl3ee81df2008-05-17 18:14:43 +00003012- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3013 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003014 to compact the internal free lists of pre-allocted ints and floats.
3015
Georg Brandl3ee81df2008-05-17 18:14:43 +00003016- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3017 calls. Python expected the return type int but the fork familie
3018 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003019

Georg Brandl3ee81df2008-05-17 18:14:43 +00003032- Patch #1473257: generator objects gain a gi_code attribute. This is
3033 the same object as the func_code attribute of the function that
3034 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003035
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036- Issue #1920: "while 0" statements were completely removed by the
3037 compiler, even in the presence of an "else" clause, which is
3038 supposed to be run when the condition is false. Now the compiler
3039 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003040

Georg Brandl3ee81df2008-05-17 18:14:43 +00003067- Objects/structseq.c: Implemented new structseq representation. The
3068 patch makes structseqs (e.g. the return value of os.stat) more
3069 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003070
Georg Brandl3ee81df2008-05-17 18:14:43 +00003071- Patch #1700288: added a type attribute cache that caches method
3072 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003073
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003074- Bug #1776: __import__() no longer accepts filenames on any platform.
3075 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00003077- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3078
Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3080 envvar and sys.dont_write_bytecode attribute. All these can be set
3081 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003082
Georg Brandl3ee81df2008-05-17 18:14:43 +00003083- Improve some exception messages when Windows fails to load an
3084 extension module. Now we get for example '%1 is not a valid Win32
3085 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003086

Christian Heimes0a8143f2007-12-18 23:22:54 +00003092- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093 and INF. float("nan"), float("inf") and float("-inf") now work on
3094 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003096- Compiler now generates simpler and faster code for dictionary
3097 literals. The oparg for BUILD_MAP now indicates an estimated
3098 dictionary size. There is a new opcode, STORE_MAP, for adding
3099 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003128- Patch #1739468: Directories and zipfiles containing a __main__.py
3129 file can now be directly executed by passing their name to the
3130 interpreter. The directory/zipfile is automatically inserted as the
3131 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003133- Issue #1265: Fix a problem with sys.settrace, if the tracing
3134 function uses a generator expression when at the same time the
3135 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003136
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003137- sets and frozensets now have an isdisjoint() method.

3140
Neal Norwitz44f326e2007-10-05 05:29:17 +00003141- Fix warnings found by the new version of the Coverity checker.
3142
Georg Brandl3ee81df2008-05-17 18:14:43 +00003143- The enumerate() builtin function is no longer bounded to sequences
3144 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3145 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003146
Georg Brandl3ee81df2008-05-17 18:14:43 +00003147- Issue #1686386: Tuple's tp_repr did not take into account the
3148 possibility of having a self-referential tuple, which is possible
3149 from C code. Nor did object's tp_str consider that a type's tp_str
3150 could do something that could lead to an inifinite recursion.
3151 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3152 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003153
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- Issue #1164: It was possible to trigger deadlock when using the
3155 'print' statement to write to a file since the GIL was not released
3156 as needed. Now PyObject_Print() does the right thing along with
3157 various tp_print implementations of the built-in types and those in
3158 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003159
Georg Brandl3ee81df2008-05-17 18:14:43 +00003160- Issue #1147: Exceptions were directly allowing string exceptions in

3162 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00003166
Brett Cannon1e534b52007-09-07 04:18:30 +00003167- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003168 PyObject_Call() never calling back out to Python code to trigger
3169 recursion depth updates/checks. Required the creation of a static
3170 RuntimeError instance in case normalizing an exception put the
3171 recursion check value past its limit. Fixes crashers
3172 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003187- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003188 __*__ attributes. (Some already existed, e.g., __doc__ and
3189 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003190
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003191- Add -3 option to the interpreter to warn about features that are
3192 deprecated and will be changed/removed in Python 3.0.
3193
Georg Brandl2134e752007-05-21 20:34:16 +00003194- Patch #1686487: you can now pass any mapping after '**' in function
3195 calls.
3196
Collin Winter62903052007-05-18 23:11:24 +00003197- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003198 "except E as target:". This is to provide forwards compatibility
3199 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003200
Brett Cannon229cee22007-05-05 01:34:02 +00003201- Deprecate BaseException.message as per PEP 352.

3205
Vinay Sajip8549ce32007-05-06 17:53:37 +00003206- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003207 setting a plain string, ie don't expand to single letter identifiers.
3208
Raymond Hettinger13936692007-04-11 18:40:58 +00003209- Request #1191699: Slices can now be pickled.
3210
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003211- Request #1193128: str.translate() now allows a None argument for
3212 translations that only remove characters without re-mapping the
3213 remaining characters.
3214
Georg Brandl5cb76c12007-03-21 09:00:39 +00003215- Patch #1682205: a TypeError while unpacking an iterable is no longer
3216 masked by a generic one with the message "unpack non-sequence".
3217
Neal Norwitzaa754b72007-03-21 06:39:48 +00003218- Remove unused file Python/fmod.c.
3219
Guido van Rossum143b5642007-03-23 04:58:42 +00003220- Bug #1683368: The object.__init__() and object.__new__() methods are
3221 now stricter in rejecting excess arguments. The only time when
3222 either allows excess arguments is when it is not overridden and the
3223 other one is. For backwards compatibility, when both are
3224 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003225 warning later). Also, type.__init__() insists on the same signature
3226 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003227
Georg Brandl3ee81df2008-05-17 18:14:43 +00003228- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3229 object to complex using its __complex__() method before falling back
3230 to the __float__() method. Therefore, the functions in the cmath
3231 module now can operate on objects that define a __complex__()
3232 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003233
Georg Brandl3ee81df2008-05-17 18:14:43 +00003234- Patch #1623563: allow __class__ assignment for classes with
3235 __slots__. The old and the new class are still required to have the
3236 same slot names.

3249
Georg Brandl7b9c5552007-03-12 14:30:05 +00003250- Bug #1678647: write a newline after printing an exception in any
3251 case, even when converting the value to a string failed.
3252
Georg Brandl871f1bc2007-03-12 13:17:36 +00003253- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254 its argument, if it exists. If not, it will work like before. This
3255 allows customizing the output of dir() in the presence of a
3256 __getattr__().

3265 parthensized forms. This means complex(repr(x)) now works instead of
3266 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003267
Georg Brandlaa2321b2007-03-07 00:40:28 +00003268- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003269 makes the filenames the warning module prints much more sensible
3270 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003271

Georg Brandl0fca97a2007-03-05 22:28:08 +00003283- Patch #1674228: when assigning a slice (old-style), check for the
3284 sq_ass_slice instead of the sq_slice slot.
3285
Georg Brandl3ee81df2008-05-17 18:14:43 +00003286- When printing an unraisable error, don't print exceptions. before
3287 the name. This duplicates the behavior whening normally printing
3288 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003821 AttributeError instead of an IOError when the server's response
3822 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003823

Georg Brandl3ee81df2008-05-17 18:14:43 +00003828- Patch #1429539: pdb now correctly initializes the __main__ module
3829 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003830 correctly now.
3831

3838
Georg Brandl3ee81df2008-05-17 18:14:43 +00003839- Patch #1530482: add pydoc.render_doc() which returns the

3854
Georg Brandl92a6bae2007-03-13 17:43:32 +00003855- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003856 are set for invalid interpolation sequences that would lead to
3857 errors on reading back those values.

3900 returned string up to the first NUL character.

3911
Georg Brandl3ee81df2008-05-17 18:14:43 +00003912- unittest now verifies more of its assumptions. In particular,
3913 TestCase and TestSuite subclasses (not instances) are no longer
3914 accepted in TestSuite.addTest(). This should cause no
3915 incompatibility since it never made sense with ordinary subclasses
3916 -- the failure just occurred later, with a more cumbersome
3917 exception.

3927
Georg Brandl3ee81df2008-05-17 18:14:43 +00003928- Patch #1673619: setup.py identifies extension modules it doesn't

4277 contents before adding elements from the iterable. This fix brings
4278 the behavior into line with that for list.__init__().

4288 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4289 silently miscode subclasses of those types. Now, it raises a
4290 ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004305- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004306 time so that opening a database previously created with the DB_DUP
4307 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4308 opens. Specifically: dictionary assignment to a DB object will
4309 replace all values for a given key when the database allows
4310 duplicate values. DB users should use DB.put(k, v) when they want
4311 to store duplicates; not DB[k] = v.

4318 characters with ASCII value less than 32. Also, it correctly quotes
4319 dots only if they occur on a single line, as opposed to the previous
4320 behavior of quoting dots if they are the second character of any
4321 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004699- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4700 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
