Benjamin Petersonddd392c2009-12-13 19:19:07 +000023- Issue #7349: Make methods of file objects in the io module accept None as an
24 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
25 the same as passing no argument.
26
Benjamin Petersonc4771d22009-12-13 17:31:31 +000027- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
28 like other file objects.

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000050- Issue #7419: setlocale() could crash the interpreter on Windows when called
51 with invalid values.
52
Eric Smithc4ab8332009-11-29 17:40:57 +000053- Issue #3382: 'F' formatting for float and complex now convert the
54 result to upper case. This only affects 'inf' and 'nan', since 'f'
55 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000056
Mark Dickinson9dd5e162009-11-23 20:54:09 +000057- Remove switch from "%f" formatting to "%g" formatting for floats
58 larger than 1e50 in absolute value.
59
Mark Dickinson18cfada2009-11-23 18:46:41 +000060- Remove restrictions on precision when formatting floats. E.g.,
61 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
62 requested 120 significant digits instead.
63
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000064- Add Py3k warnings for parameter names in parenthesis.

Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000066- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000067
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000068- Issue #7085: Fix crash when importing some extensions in a thread
69 on MacOSX 10.6.
70
Mark Dickinsonb678de82009-11-19 18:41:49 +000071- Issue #7117: repr(x) for a float x returns a result based on the
72 shortest decimal string that's guaranteed to round back to x under
73 correct rounding (with round-half-to-even rounding mode).
74 Previously it gave a string based on rounding x to 17 decimal digits.
75 repr(x) for a complex number behaves similarly. On platforms where
76 the correctly-rounded strtod and dtoa code is not supported (see below),
77 repr is unchanged.
78
79- Issue #7117: On almost all platforms: float-to-string and
80 string-to-float conversions within Python are now correctly rounded.
81 Places these conversions occur include: str for floats and complex
82 numbers; the float and complex constructors; old-style and new-style
83 numeric formatting; serialization and deserialization of floats and
84 complex numbers using marshal, pickle and json; parsing of float and
85 imaginary literals in Python code; Decimal-to-float conversion.
86
87 The conversions use a Python-adapted version of David Gay's
88 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
89 functions. This code is supported on Windows, and on Unix-like
90 platforms using gcc, icc or suncc as the C compiler. There may be a
91 small number of platforms on which correct operation of this code
92 cannot be guaranteed, so the code is not used: notably, this applies
93 to platforms where the C double format is not IEEE 754 binary64, and
94 to platforms on x86 hardware where the x87 FPU is set to 64-bit
95 precision and Python's configure script is unable to determine how
96 to change the FPU precision. On these platforms conversions use the
97 platform strtod and dtoa, as before.
98
Mark Dickinsonbd15a062009-11-18 19:33:35 +000099- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000100 now uses the correctly-rounded string <-> float conversions
101 described above (when available), and so produces correctly rounded
102 results that will display nicely under the float repr. There are
103 two related small changes: (1) round now accepts any class with an
104 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000105 floats for the second argument), and (2) an excessively large second
106 integer argument (e.g., round(1.234, 10**100)) no longer raises an
107 exception.
108
Philip Jenveyfab8be22009-11-17 02:42:26 +0000109- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
110
Benjamin Petersone36199b2009-11-12 23:39:44 +0000111- Fix several issues with compile(). The input can now contain Windows and Mac
112 newlines and is no longer required to end in a newline.
113

115 unicode string.
116
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000117- Issue #7244: itertools.izip_longest() no longer ignores exceptions
118 raised during the formation of an output tuple.
119

124 interpreter is killed. Patch by Adam Olsen.
125
Eric Smithc12781a2009-10-19 14:38:14 +0000126- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

252 was locale aware; and (3) the interpretation of fromhex('-nan')
253 didn't match that of float('-nan').
254
Eric Smitha985a3a2009-05-05 18:26:08 +0000255- Issue #5920: For float.__format__, change the behavior with the
256 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
257 to be like 'g' but with at least one decimal point and with a
258 default precision of 12. Previously, the behavior the same but with
259 a default precision of 6. This more closely matches str(), and
260 reduces surprises when adding alignment flags to the empty
261 presentation type. This also affects the new complex.__format__ in
262 the same way.
263
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000264- Issue #5890: in subclasses of 'property' the __doc__ attribute was

292 floats, ints, and longs.
293
294- Issue #5515: 'n' formatting for ints, longs, and floats handles
295 leading zero formatting poorly.
296
297- Issue #5772: For float.__format__, don't add a trailing ".0" if
298 we're using no type code and we have an exponent.

328 reduce the size of collections and therefore the garbage collection overhead
329 on long-running programs, depending on their particular use of datatypes.

334
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000335- Issue #4258: Make it possible to use base 2**30 instead of base
336 2**15 for the internal representation of integers, for performance
337 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
338 --enable-big-digits option to configure, which overrides the
339 default. Add sys.long_info structseq to provide information about
340 the internal format.

373
Georg Brandl29c6a282009-04-05 20:23:13 +0000374- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000375 were suppressing all exceptions. These include list(), filter(), map(),
376 zip(), and bytearray().
377
Benjamin Peterson596d3062009-01-19 15:42:23 +0000378- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000397- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
398 collecting the oldest generation) so that allocating lots of objects without
399 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000400 Martin von Löwis at

404
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000405- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
406 an existing .py counterpart, override the co_filename attributes of all
407 code objects if the original filename is obsolete (which can happen if the
408 file has been renamed, moved, or if it is accessed through different paths).
409 Patch by Ziga Seilnacht and Jean-Paul Calderone.

421
Benjamin Peterson7af65562008-12-29 17:56:58 +0000422- Issue #4764: With io.open, IOError.filename is set when trying to open a

430
Skip Montanarof205c132008-12-23 03:30:15 +0000431- Added test case to ensure attempts to read from a file opened for writing
432 fail.
433
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000434- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

447 exceptions.
448
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000449- Issue #4445: Replace "sizeof(PyStringObject)" with
450 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
451 str instances. On a typical machine this saves 3 bytes of memory
452 (on average) per string allocation.
453
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000454- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
455 interpreter to abort ("Fatal Python error: Could not reset the stack!")
456 instead of throwing a MemoryError.
457
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000458- Issue #3689: The list reversed iterator now supports __length_hint__

460
Benjamin Petersonc078f922008-11-21 22:27:24 +0000461- Issue #4367: Python would segfault during compiling when the unicodedata

463
Vinay Sajip213faca2008-12-03 23:22:58 +0000464- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000465 method on file objects with closefd=False. The file descriptor is still
466 kept open but the file object behaves like a closed file. The ``FileIO``
467 object also got a new readonly attribute ``closefd``.
468
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000469- Issue #4348: Some bytearray methods returned that didn't cause any change to
470 the bytearray, returned the same bytearray instead of a copy.
471

480
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000481- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
482 method does not return iterators for the 4th and 5th items.
483
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000484- Issue #4209: Enabling unicode_literals and the print_function in the same
485 __future__ import didn't work.
486
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000487- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000488 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000490- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
491 returned a path longer than MAX_PATH. (But It's doubtful this code path is
492 really executed because I cannot move to such directory on win2k)
493
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000494- Issue #4069: When set.remove(element) is used with a set element, the element
495 is temporarily replaced with an equivalent frozenset. But the eventual
496 KeyError would always report the empty frozenset([]) as the missing key. Now
497 it correctly refers to the initial element.
498
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000499- Issue #4509: Various issues surrounding resize of bytearray objects to

515 returned them on 64bit platforms.
516
Walter Dörwalded960ac2009-05-03 22:36:33 +0000517- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
518 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
519 step. This avoids problems with counting UTF-8 bytes that ignores the effect
520 of using the replace error handler in PyUnicode_DecodeUTF8().
521
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000522- Issue #3739: The unicode-internal encoder now reports the number of characters
523 consumed like any other encoder (instead of the number of bytes).
524
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000525- Issue #2422: When compiled with the ``--with-valgrind`` option, the
526 pymalloc allocator will be automatically disabled when running under
527 Valgrind. This gives improved memory leak detection when running
528 under Valgrind, while taking advantage of pymalloc at other times.

598 to execute file paths that refer to source or compiled Python files as well
599 as zipfiles, directories and other valid sys.path entries that contain a
600 __main__.py file. This allows applications that run other Python scripts to
601 support the same flexibility as the CPython command line itself.

1698 integer now consistently raises struct.error.
1699
Mark Dickinson463dc4b2009-07-05 10:01:24 +00001700- Issues #1530559, #1741130: Fix various struct.pack inconsistencies
1701 for the integer formats ('bBhHiIlLqQ'). In the following, '*'
1702 represents any of '=', '<', '>'.
1703
1704 - Packing a float now always gives a Deprecation Warning.
1705 Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
1706
1707 - If x is not an int, long or float, then packing x will always
1708 result in struct.error. Previously an x with an __int__ method
1709 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1710 ,'*i', '*l', and an x with a __long__ method could be packed by
1711 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
1712 TypeError used to be raised (with a confusing error message) for
1713 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001907- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

1909 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1910 ``printf`` function, whereas PyString_FromFormat has an independent
1911 implementation and uses "%zd" on all platforms for size_t values.
1912 This makes a difference on win64, where ``printf`` needs "%Id" to display
1913 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001933 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

1936 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1937 type object.

2008 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2009 for catch_warnings() also led to an improvement in the raising of a
2010 DeprecationWarning related to warnings.warn_explicit().

2034
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002035- Issue #2975: When compiling several extension modules with Visual Studio 2008
2036 from the same python interpreter, some environment variables would grow
2037 without limit.
2038
Benjamin Peterson37346b22008-08-23 20:27:43 +00002039- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002076What's New in Python 2.6 beta 3?
2077================================
2078
Barry Warsaw07a4a382008-08-21 01:15:08 +00002079*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002080
2081Core and Builtins
2082-----------------
2083
Guido van Rossumf8402962008-08-20 15:01:50 +00002084- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2085 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2086 extensions do not automatically benefit from the class attribute
2087 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2088 to their tp_flags field if they care. This is a backwards
2089 compatibility feature; in 3.0, all types will use the cache by
2090 default.
2091
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002092- Keyword arguments can now follow starred arguments. (``f(a, *args,
2093 keyword=23)`` is now valid syntax.)
2094
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002095- ctypes function pointers that are COM methods have a boolean True
2096 value again.
2097
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002098- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2099 by denying s# to parse objects that have a releasebuffer procedure,
2100 and introducing s*.
2101
Georg Brandl1e13ea92008-08-11 09:07:59 +00002102- Issue #3537: Fix an assertion failure when an empty but presized dict
2103 object was stored in the freelist.
2104
Mark Dickinsonb6467572008-08-04 21:30:09 +00002105- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2106 ValueError consistently across platforms.
2107
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002108- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2109 (64bit Unix, for example), unichr() would truncate its argument and return
2110 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2111
Neal Norwitze7d8be82008-07-31 17:17:14 +00002112- Apply security patches from Apple.
2113
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002114- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2115 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2116
Antoine Pitrou92f82162008-07-25 22:22:08 +00002117- Issue #1819: function calls with several named parameters are now on
2118 average 35% faster (as measured by pybench).
2119
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002120- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2121 the python debugger steps into a class statement: the free variables (local
2122 variables defined in an outer scope) would be deleted from the outer scope.
2123
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002124- Issue #2620: Overflow checking when allocating or reallocating memory
2125 was not always being done properly in some python types and extension
2126 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2127 all been updated to perform better checks and places in the code that
2128 would previously leak memory on the error path when such an allocation
2129 failed have been fixed.
2130
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002131Library
2132-------
2133

2135
Benjamin Petersone977ad42008-08-20 01:42:01 +00002136- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2137 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2138
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002139- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2140 version reported by these tools does not necessarily follow the python
2141 version numbering scheme, so the module is less strict when parsing it.
2142
Nick Coghlanf70385a2008-08-18 12:42:46 +00002143- Issue #2235: Added Py3k warnings for types which will become unhashable
2144 under the stricter __hash__ inheritance rules in 3.0. Several types
2145 which did not meet the rules for hash invariants and were already
2146 unhashable in 3.0 have now been explicitly flagged as unhashable in
2147 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2148 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2149
Brett Cannon88f801d2008-08-18 00:46:22 +00002150- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2158
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002159- Issue #3575: Incremental decoder's decode function now takes bytearray
2160 by using 's*' instead of 't#'.
2161
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002162- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002163 fails unicode conversion on 2nd parameter. (windows only)
2164
Facundo Batista94f243a2008-08-17 03:38:39 +00002165- Issue 2464. urllib2 now supports a malformation in the URL received
2166 in a redirect.
2167
Brett Cannonabe423e2008-08-16 21:47:07 +00002168- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002169 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002170
Facundo Batistaeb90b782008-08-16 14:44:07 +00002171- Issue #2776: fixed small issue when handling an URL with double slash
2172 after a 302 response in the case of not going through a proxy.
2173
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002174- Issue #2676: in the email package, content-type parsing was hanging on
2175 pathological input because of quadratic or exponential behaviour of a
2176 regular expression.
2177
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002178- Issue #3476: binary buffered reading through the new "io" library is now
2179 thread-safe.
2180
Brett Cannonbf3157b2008-08-14 05:00:03 +00002181- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2182 since mimetools itself is deprecated. Because modules are cached, all
2183 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2184
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002185- Issue #3134: shutil referenced undefined WindowsError symbol.
2186
Robert Schuppenies14646332008-08-10 11:01:53 +00002187- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2188 menu entries were not deleted.
2189
Brett Cannon83e81842008-08-09 23:30:55 +00002190- Copied the implementation of reduce() to _functools.reduce() to have a
2191 version that did not raise a DeprecationWarning under -3.
2192
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002193- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2194 a MemoryError rather than silently stop the iteration.
2195
Guido van Rossum59ce9012008-08-09 14:55:34 +00002196- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2197 to _sre.compile() will now be rejected. This should not affect anybody
2198 since the re.compile() function never generates invalid re-bytecode.
2199
Skip Montanaroa032bf42008-08-08 22:52:51 +00002200- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00002219 asking for a specific length. This problem only affected files opened
2220 using the new "io" module, not the built-in open() function.

Eric Smitha5fa5a22008-07-16 00:11:49 +00002285- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2286 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2287
Mark Dickinson7103aa42008-07-15 19:08:33 +00002288- Issue #3008: the float type has a new instance method 'float.hex'
2289 and a new class method 'float.fromhex' to convert floating-point
2290 numbers to and from hexadecimal strings, respectively.
2291
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002292- Issue #2235: __hash__ is once again inherited by default. To allow
2293 collections.Hashable to remain meaningful in the presence of the
2294 default hash implementation (object.__hash__), it is now possible
2295 to explicit block inheritance of hash by setting __hash__=None at
2296 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2297 level.
2298
Nick Coghlanb028f502008-07-13 14:52:36 +00002299- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2300 the parent module cannot be found while performing an absolute import.
2301 This means that an incorrectly defined __package__ attribute will
2302 now only prevent relative imports in that module rather than causing
2303 all imports from that module to fail.
2304
Nick Coghlan14ff9942008-07-08 14:21:42 +00002305- Issue #2517: Allow unicode messages in Exceptions again by correctly

2316
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002317- Issue #3004: Minor change to slice.indices(): the start and stop
2318 arguments are now treated identically, making the behaviour easier
2319 to describe and understand. For example, slice(None, -10,
2320 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2321 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2322 10, -1).

2326 from 2.4 caused by the switch to the new compiler.

2365 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002366 wrong because the actual transmitted size could differ from the

2841 use of pure Python code is not possible. Both the ``showarning()``
2842 and ``formatwarning()`` gain an optional 'line' argument which is
2843 not called by default for backwards-compatibility reasons. Setting
2844 ``warnings.showwarning()`` to an implementation that lacks support
2845 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002908- Issue #2550: The approach used by client/server code for obtaining
2909 ports to listen on in network-oriented tests has been refined in an
2910 effort to facilitate running multiple instances of the entire
2911 regression test suite in parallel without issue.
2912 test_support.bind_port() has been fixed such that it will always
2913 return a unique port -- which wasn't always the case with the
2914 previous implementation, especially if socket options had been set
2915 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2916 new implementation of bind_port() will actually raise an exception
2917 if it is passed an AF_INET/SOCK_STREAM socket with either the
2918 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2919 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2920 the socket it's been passed. This currently only applies to
2921 Windows. This option prevents any other sockets from binding to the
2922 host/port we've bound to, thus removing the possibility of the
2923 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2924 when a second SOCK_STREAM socket binds and accepts to a host/port
2925 that's already been bound by another socket. The optional preferred
2926 port parameter to bind_port() has been removed. Under no
2927 circumstances should tests be hard coding ports!
2928
2929 test_support.find_unused_port() has also been introduced, which will
2930 pass a temporary socket object to bind_port() in order to obtain an
2931 unused port. The temporary socket object is then closed and
2932 deleted, and the port is returned. This method should only be used
2933 for obtaining an unused port in order to pass to an external program
2934 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2935 a parameter to a server-oriented class that doesn't give you direct
2936 access to the underlying socket used.
2937
2938 Finally, test_support.HOST has been introduced, which should be used
2939 for the host argument of any relevant socket calls (i.e. bind and
2940 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002941
2942 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002943 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002944 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2945 test_asynchat and test_socket_ssl.
2946
Georg Brandl3ee81df2008-05-17 18:14:43 +00002947 It is now possible for multiple instances of the regression test
2948 suite to run in parallel without issue.

3215-----------------
3216
Fred Drakea8ee94b2008-03-01 02:45:07 +00003217- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003218 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003220- Issue #2067: file.__exit__() now calls subclasses' close() method.
3221
3222- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003223
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003224- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003225 issue 215555 for a discussion.
3226
Eric Smitha73fbe72008-02-23 03:09:44 +00003227- Added the future_builtins module, which contains hex() and oct().
3228 These are the PEP 3127 version of these functions, designed to be
3229 compatible with the hex() and oct() builtins from Python 3.0. They
3230 differ slightly in their output formats from the existing, unchanged
3231 Python 2.6 builtins. The expected usage of the future_builtins
3232 module is:
3233 from future_builtins import hex, oct
3234
Eric Smith7ef40bf2008-02-20 23:34:22 +00003235- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3236 exponents for exponents with absolute value < 100. Follows C99
3237 standard. This is a change on Windows, which would use 3 digits.
3238 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3239 so that any alterations it does to the resulting string will be
3240 available in stringlib/formatter.h (for float.__format__).
3241
Eric Smith5a3c1352008-02-19 13:21:56 +00003242- Implemented PEP 3101, Advanced String Formatting. This adds a new
3243 builtin format(); a format() method for str and unicode; a
3244 __format__() method to object, str, unicode, int, long, float, and
3245 datetime; the class string.Formatter; and the C API
3246 PyObject_Format().
3247
Georg Brandl3ee81df2008-05-17 18:14:43 +00003248- Fixed several potential crashes, all caused by specially crafted
3249 __del__ methods exploiting objects in temporarily inconsistent
3250 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003251
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003252- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003253 prevent a possible crash: an Abstract Base Class would try to access
3254 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003255
Georg Brandl3ee81df2008-05-17 18:14:43 +00003256- Fixed repr() and str() of complex numbers with infinity or nan as
3257 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003258
Georg Brandl3ee81df2008-05-17 18:14:43 +00003259- Clear all free lists during a gc.collect() of the highest generation
3260 in order to allow pymalloc to free more arenas. Python may give back
3261 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003262
Georg Brandl3ee81df2008-05-17 18:14:43 +00003263- Issue #2045: Fix an infinite recursion triggered when printing a
3264 subclass of collections.defaultdict, if its default_factory is set
3265 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003266
Christian Heimesf75dbef2008-02-08 00:11:31 +00003267- Fixed a minor memory leak in dictobject.c. The content of the free
3268 list was not freed on interpreter shutdown.
3269
Georg Brandl3ee81df2008-05-17 18:14:43 +00003270- Limit free list of method and builtin function objects to 256
3271 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003272
Georg Brandl3ee81df2008-05-17 18:14:43 +00003273- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3274 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003275 to compact the internal free lists of pre-allocted ints and floats.
3276
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3278 calls. Python expected the return type int but the fork familie
3279 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003280
Georg Brandl3ee81df2008-05-17 18:14:43 +00003281- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3282 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3285 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003286

3288 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003289
Georg Brandl3ee81df2008-05-17 18:14:43 +00003290- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3291 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003292
Georg Brandl3ee81df2008-05-17 18:14:43 +00003293- Patch #1473257: generator objects gain a gi_code attribute. This is
3294 the same object as the func_code attribute of the function that
3295 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003296
Georg Brandl3ee81df2008-05-17 18:14:43 +00003297- Issue #1920: "while 0" statements were completely removed by the
3298 compiler, even in the presence of an "else" clause, which is
3299 supposed to be run when the condition is false. Now the compiler
3300 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003301
Guido van Rossumeead05f2008-01-24 18:21:02 +00003302- A few crashers fixed: weakref_in_del.py (issue #1377858);
3303 loosing_dict_ref.py (issue #1303614, test67.py);
3304 borrowed_ref_[34].py (not in tracker).
3305
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003306- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003307 suppressed while an extension is loaded by calling SetErrorMode in
3308 dynload_win.c. The error is still reported properly.
3309
Georg Brandl3ee81df2008-05-17 18:14:43 +00003310- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003311 several extension methods and modules do not work without unicode
3312 support.
3313
Georg Brandl26543b12008-01-21 18:36:51 +00003314- Issue #1882: when compiling code from a string, encoding cookies in the
3315 second line of code were not always recognized correctly.
3316
Georg Brandl14404b62008-01-19 19:27:05 +00003317- Issue #1679: "0x" was taken as a valid integer literal.
3318
Georg Brandl6caad7d2008-01-26 14:19:22 +00003319- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003320 added.
3321
Christian Heimesc94e2b52008-01-14 04:13:37 +00003322- sys.float_info / PyFloat_GetInfo: The floating point information
3323 object was converted from a dict to a specialized structseq object.
3324
Georg Brandl3ee81df2008-05-17 18:14:43 +00003325- Patch #1816: Added sys.flags structseq. It exposes the status of
3326 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003327
Georg Brandl3ee81df2008-05-17 18:14:43 +00003328- Objects/structseq.c: Implemented new structseq representation. The
3329 patch makes structseqs (e.g. the return value of os.stat) more
3330 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003331
Georg Brandl3ee81df2008-05-17 18:14:43 +00003332- Patch #1700288: added a type attribute cache that caches method
3333 accesses, resulting in speedups in heavily object-oriented code.

3342 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003343
Georg Brandl3ee81df2008-05-17 18:14:43 +00003344- Improve some exception messages when Windows fails to load an
3345 extension module. Now we get for example '%1 is not a valid Win32
3346 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003347

Georg Brandl3ee81df2008-05-17 18:14:43 +00003357- Compiler now generates simpler and faster code for dictionary
3358 literals. The oparg for BUILD_MAP now indicates an estimated
3359 dictionary size. There is a new opcode, STORE_MAP, for adding
3360 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003389- Patch #1739468: Directories and zipfiles containing a __main__.py
3390 file can now be directly executed by passing their name to the
3391 interpreter. The directory/zipfile is automatically inserted as the
3392 first entry in sys.path.

3403
Georg Brandl3ee81df2008-05-17 18:14:43 +00003404- The enumerate() builtin function is no longer bounded to sequences
3405 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3406 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003407
Georg Brandl3ee81df2008-05-17 18:14:43 +00003408- Issue #1686386: Tuple's tp_repr did not take into account the
3409 possibility of having a self-referential tuple, which is possible
3410 from C code. Nor did object's tp_str consider that a type's tp_str
3411 could do something that could lead to an inifinite recursion.
3412 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3413 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003414
Georg Brandl3ee81df2008-05-17 18:14:43 +00003415- Issue #1164: It was possible to trigger deadlock when using the
3416 'print' statement to write to a file since the GIL was not released
3417 as needed. Now PyObject_Print() does the right thing along with
3418 various tp_print implementations of the built-in types and those in
3419 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00003428- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429 PyObject_Call() never calling back out to Python code to trigger
3430 recursion depth updates/checks. Required the creation of a static
3431 RuntimeError instance in case normalizing an exception put the
3432 recursion check value past its limit. Fixes crashers
3433 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003448- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003449 __*__ attributes. (Some already existed, e.g., __doc__ and
3450 __name__.)

3456 calls.
3457
Collin Winter62903052007-05-18 23:11:24 +00003458- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003459 "except E as target:". This is to provide forwards compatibility
3460 with Python 3.0.

3466
Vinay Sajip8549ce32007-05-06 17:53:37 +00003467- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003468 setting a plain string, ie don't expand to single letter identifiers.
3469
Raymond Hettinger13936692007-04-11 18:40:58 +00003470- Request #1191699: Slices can now be pickled.
3471
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003472- Request #1193128: str.translate() now allows a None argument for

3474 remaining characters.
3475
Georg Brandl5cb76c12007-03-21 09:00:39 +00003476- Patch #1682205: a TypeError while unpacking an iterable is no longer

3480
Guido van Rossum143b5642007-03-23 04:58:42 +00003481- Bug #1683368: The object.__init__() and object.__new__() methods are
3482 now stricter in rejecting excess arguments. The only time when
3483 either allows excess arguments is when it is not overridden and the
3484 other one is. For backwards compatibility, when both are
3485 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003486 warning later). Also, type.__init__() insists on the same signature
3487 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003488
Georg Brandl3ee81df2008-05-17 18:14:43 +00003489- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3490 object to complex using its __complex__() method before falling back
3491 to the __float__() method. Therefore, the functions in the cmath
3492 module now can operate on objects that define a __complex__()
3493 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003495- Patch #1623563: allow __class__ assignment for classes with
3496 __slots__. The old and the new class are still required to have the
3497 same slot names.

3504 its type.

3510
Georg Brandl7b9c5552007-03-12 14:30:05 +00003511- Bug #1678647: write a newline after printing an exception in any
3512 case, even when converting the value to a string failed.
3513
Georg Brandl871f1bc2007-03-12 13:17:36 +00003514- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003515 its argument, if it exists. If not, it will work like before. This
3516 allows customizing the output of dir() in the presence of a
3517 __getattr__().

3521
Georg Brandl3ee81df2008-05-17 18:14:43 +00003522- Patch #1675981: remove unreachable code from ``type.__new__()``

3526 parthensized forms. This means complex(repr(x)) now works instead of
3527 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003528
Georg Brandlaa2321b2007-03-07 00:40:28 +00003529- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003530 makes the filenames the warning module prints much more sensible
3531 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003544- Patch #1674228: when assigning a slice (old-style), check for the
3545 sq_ass_slice instead of the sq_slice slot.
3546
Georg Brandl3ee81df2008-05-17 18:14:43 +00003547- When printing an unraisable error, don't print exceptions. before

4115
Georg Brandl92a6bae2007-03-13 17:43:32 +00004116- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004117 are set for invalid interpolation sequences that would lead to
4118 errors on reading back those values.

4174 TestCase and TestSuite subclasses (not instances) are no longer
4175 accepted in TestSuite.addTest(). This should cause no
4176 incompatibility since it never made sense with ordinary subclasses
4177 -- the failure just occurred later, with a more cumbersome
4178 exception.

4461 obtained from the TLS negotiation itself. Patch contributed by Bill
4462 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004463
Georg Brandl3ee81df2008-05-17 18:14:43 +00004464- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004465 that the SMTP.starttls() caller no longer needs to call ehlo()
4466 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004467 does not claim to support starttls. Adds the
4468 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00004552

Georg Brandl3ee81df2008-05-17 18:14:43 +00004567 time so that opening a database previously created with the DB_DUP
4568 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4569 opens. Specifically: dictionary assignment to a DB object will
4570 replace all values for a given key when the database allows
4571 duplicate values. DB users should use DB.put(k, v) when they want

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004851- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004852 periodic threadstate and signal checking in tight loops. By
4853 default, this option is turned-off. It should only be enabled in
4854 debugged, performance critical applications.

4906
Georg Brandl3ee81df2008-05-17 18:14:43 +00004907- Unified naming convention for free lists and their limits. All free
4908 lists in Object/ are named ``free_list``, the counter ``numfree``
4909 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4910 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004911
Georg Brandl3ee81df2008-05-17 18:14:43 +00004912- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4913 to ``PyTuple_SetItem``, it can be used to populate a brand new
4914 frozenset; but it does not steal a reference to the added item.

4926
Georg Brandl3ee81df2008-05-17 18:14:43 +00004927- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4928 of w# format code incorrectly truncated the length to an int, even
4929 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4930 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004931

4952
4953- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4954 outside of pystate.c and should not be necessary.
4955
Georg Brandl3ee81df2008-05-17 18:14:43 +00004956- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4957 absolute imports. In earlier versions they might have used relative
4958 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004959
Georg Brandl3ee81df2008-05-17 18:14:43 +00004960- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4961 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004962
Georg Brandl3ee81df2008-05-17 18:14:43 +00004963- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004988- Removed the macfs module. It had been deprecated since Python 2.5.
4989 This lead to the deprecation of macostools.touched() as it relied
