Benjamin Petersonddd392c2009-12-13 19:19:07 +000026- Issue #7349: Make methods of file objects in the io module accept None as an
27 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
28 the same as passing no argument.
29
Benjamin Petersonc4771d22009-12-13 17:31:31 +000030- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
31 like other file objects.

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000053- Issue #7419: setlocale() could crash the interpreter on Windows when called
54 with invalid values.
55
Eric Smithc4ab8332009-11-29 17:40:57 +000056- Issue #3382: 'F' formatting for float and complex now convert the
57 result to upper case. This only affects 'inf' and 'nan', since 'f'
58 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000059
Mark Dickinson9dd5e162009-11-23 20:54:09 +000060- Remove switch from "%f" formatting to "%g" formatting for floats
61 larger than 1e50 in absolute value.
62
Mark Dickinson18cfada2009-11-23 18:46:41 +000063- Remove restrictions on precision when formatting floats. E.g.,
64 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
65 requested 120 significant digits instead.
66
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000067- Add Py3k warnings for parameter names in parenthesis.
68
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000069- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000070
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000071- Issue #7085: Fix crash when importing some extensions in a thread
72 on MacOSX 10.6.
73
Mark Dickinsonb678de82009-11-19 18:41:49 +000074- Issue #7117: repr(x) for a float x returns a result based on the
75 shortest decimal string that's guaranteed to round back to x under
76 correct rounding (with round-half-to-even rounding mode).
77 Previously it gave a string based on rounding x to 17 decimal digits.
78 repr(x) for a complex number behaves similarly. On platforms where
79 the correctly-rounded strtod and dtoa code is not supported (see below),
80 repr is unchanged.
81
82- Issue #7117: On almost all platforms: float-to-string and
83 string-to-float conversions within Python are now correctly rounded.
84 Places these conversions occur include: str for floats and complex
85 numbers; the float and complex constructors; old-style and new-style
86 numeric formatting; serialization and deserialization of floats and
87 complex numbers using marshal, pickle and json; parsing of float and
88 imaginary literals in Python code; Decimal-to-float conversion.
89
90 The conversions use a Python-adapted version of David Gay's
91 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
92 functions. This code is supported on Windows, and on Unix-like
93 platforms using gcc, icc or suncc as the C compiler. There may be a
94 small number of platforms on which correct operation of this code
95 cannot be guaranteed, so the code is not used: notably, this applies
96 to platforms where the C double format is not IEEE 754 binary64, and
97 to platforms on x86 hardware where the x87 FPU is set to 64-bit
98 precision and Python's configure script is unable to determine how
99 to change the FPU precision. On these platforms conversions use the
100 platform strtod and dtoa, as before.
101
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000102- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000103 now uses the correctly-rounded string <-> float conversions
104 described above (when available), and so produces correctly rounded
105 results that will display nicely under the float repr. There are
106 two related small changes: (1) round now accepts any class with an
107 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000108 floats for the second argument), and (2) an excessively large second
109 integer argument (e.g., round(1.234, 10**100)) no longer raises an
110 exception.
111
Philip Jenveyfab8be22009-11-17 02:42:26 +0000112- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
113
Benjamin Petersone36199b2009-11-12 23:39:44 +0000114- Fix several issues with compile(). The input can now contain Windows and Mac
115 newlines and is no longer required to end in a newline.
116
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000117- Remove length limitation when constructing a complex number from a
118 unicode string.
119
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000120- Issue #7244: itertools.izip_longest() no longer ignores exceptions
121 raised during the formation of an output tuple.
122

124
Antoine Pitrouefb60c02009-10-20 21:29:37 +0000125- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
126 fixes the problem of some exceptions being thrown at shutdown when the
127 interpreter is killed. Patch by Adam Olsen.
128
Eric Smithc12781a2009-10-19 14:38:14 +0000129- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

140 Patch by Christopher Tur Lesniewski-Laas.
141
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000142- Issue #7084: Fix a (very unlikely) crash when printing a list from one

159
Philip Jenveydbf3b252009-09-29 04:32:44 +0000160- Issue #6990: Fix threading.local subclasses leaving old state around

Eric Smitha985a3a2009-05-05 18:26:08 +0000258- Issue #5920: For float.__format__, change the behavior with the
259 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
260 to be like 'g' but with at least one decimal point and with a
261 default precision of 12. Previously, the behavior the same but with
262 a default precision of 6. This more closely matches str(), and
263 reduces surprises when adding alignment flags to the empty
264 presentation type. This also affects the new complex.__format__ in
265 the same way.

295 floats, ints, and longs.
296
297- Issue #5515: 'n' formatting for ints, longs, and floats handles
298 leading zero formatting poorly.
299

328
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000329- Issue #4688: Add a heuristic so that tuples and dicts containing only
330 untrackable objects are not tracked by the garbage collector. This can
331 reduce the size of collections and therefore the garbage collection overhead
332 on long-running programs, depending on their particular use of datatypes.
333
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000334- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

337
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000338- Issue #4258: Make it possible to use base 2**30 instead of base
339 2**15 for the internal representation of integers, for performance
340 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
341 --enable-big-digits option to configure, which overrides the
342 default. Add sys.long_info structseq to provide information about
343 the internal format.
344
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000345- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

360 float arguments.
361
Raymond Hettinger08259e82009-02-18 23:10:19 +0000362- Running Python with the -3 option now also warns about classic division
363 for ints and longs.
364
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000365- Issue #5260: Long integers now consume less memory: average
366 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
367 on a 64-bit system.
368
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000369- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

376
Georg Brandl29c6a282009-04-05 20:23:13 +0000377- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000378 were suppressing all exceptions. These include list(), filter(), map(),
379 zip(), and bytearray().
380
Benjamin Peterson596d3062009-01-19 15:42:23 +0000381- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

383
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000384- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

Antoine Pitrouc2f02212009-01-13 23:13:52 +0000389- Issue #4935: The overflow checking code in the expandtabs() method common
390 to str, bytes and bytearray could be optimized away by the compiler, letting
391 the interpreter segfault instead of raising an error.
392
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000393- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000400- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
401 collecting the oldest generation) so that allocating lots of objects without
402 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000403 Martin von Löwis at

407
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000408- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
409 an existing .py counterpart, override the co_filename attributes of all
410 code objects if the original filename is obsolete (which can happen if the
411 file has been renamed, moved, or if it is accessed through different paths).
412 Patch by Ziga Seilnacht and Jean-Paul Calderone.
413
Martin v. Löwis5344c992009-01-02 20:32:55 +0000414- Issue #4075: Use OutputDebugStringW in Py_FatalError.

421
Nick Coghlan180e4002008-12-30 01:18:48 +0000422- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
423 where the tp_hash and tp_dict slots are both NULL.
424
Benjamin Peterson7af65562008-12-29 17:56:58 +0000425- Issue #4764: With io.open, IOError.filename is set when trying to open a

432 bytearray.translate(). It was always allowed for bytes.translate().
433
Skip Montanarof205c132008-12-23 03:30:15 +0000434- Added test case to ensure attempts to read from a file opened for writing
435 fail.
436
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000437- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

450 exceptions.
451
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000452- Issue #4445: Replace "sizeof(PyStringObject)" with
453 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
454 str instances. On a typical machine this saves 3 bytes of memory
455 (on average) per string allocation.
456
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000457- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
458 interpreter to abort ("Fatal Python error: Could not reset the stack!")
459 instead of throwing a MemoryError.
460
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000461- Issue #3689: The list reversed iterator now supports __length_hint__

463
Benjamin Petersonc078f922008-11-21 22:27:24 +0000464- Issue #4367: Python would segfault during compiling when the unicodedata

466
Vinay Sajip213faca2008-12-03 23:22:58 +0000467- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000468 method on file objects with closefd=False. The file descriptor is still
469 kept open but the file object behaves like a closed file. The ``FileIO``
470 object also got a new readonly attribute ``closefd``.
471
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000472- Issue #4348: Some bytearray methods returned that didn't cause any change to
473 the bytearray, returned the same bytearray instead of a copy.
474
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000475- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

480
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000481- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

483
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000484- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
485 method does not return iterators for the 4th and 5th items.
486
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000487- Issue #4209: Enabling unicode_literals and the print_function in the same
488 __future__ import didn't work.
489
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000490- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000491 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000492
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000493- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
494 returned a path longer than MAX_PATH. (But It's doubtful this code path is
495 really executed because I cannot move to such directory on win2k)
496
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000497- Issue #4069: When set.remove(element) is used with a set element, the element
498 is temporarily replaced with an equivalent frozenset. But the eventual
499 KeyError would always report the empty frozenset([]) as the missing key. Now
500 it correctly refers to the initial element.
501
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000502- Issue #4509: Various issues surrounding resize of bytearray objects to

518 returned them on 64bit platforms.
519
Walter Dörwalded960ac2009-05-03 22:36:33 +0000520- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
521 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
522 step. This avoids problems with counting UTF-8 bytes that ignores the effect
523 of using the replace error handler in PyUnicode_DecodeUTF8().
524
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000525- Issue #3739: The unicode-internal encoder now reports the number of characters
526 consumed like any other encoder (instead of the number of bytes).
527
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000528- Issue #2422: When compiled with the ``--with-valgrind`` option, the
529 pymalloc allocator will be automatically disabled when running under
530 Valgrind. This gives improved memory leak detection when running
531 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +0000600- Issue #6816: runpy now provides a run_path function that allows Python code
601 to execute file paths that refer to source or compiled Python files as well
602 as zipfiles, directories and other valid sys.path entries that contain a
603 __main__.py file. This allows applications that run other Python scripts to
604 support the same flexibility as the CPython command line itself.

Mark Dickinson5fd3af22009-07-07 15:08:28 +00001699- Issue #1523: Remove deprecated overflow wrapping for struct.pack
1700 with an integer format code ('bBhHiIlLqQ'). Packing an out-of-range
1701 integer now consistently raises struct.error.

1705 represents any of '=', '<', '>'.
1706
1707 - Packing a float now always gives a Deprecation Warning.
1708 Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
1709
1710 - If x is not an int, long or float, then packing x will always
1711 result in struct.error. Previously an x with an __int__ method
1712 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1713 ,'*i', '*l', and an x with a __long__ method could be packed by
1714 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
1715 TypeError used to be raised (with a confusing error message) for
1716 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001910- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1911 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1912 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1913 ``printf`` function, whereas PyString_FromFormat has an independent
1914 implementation and uses "%zd" on all platforms for size_t values.
1915 This makes a difference on win64, where ``printf`` needs "%Id" to display
1916 64bit values.

1939 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1940 type object.

2011 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2012 for catch_warnings() also led to an improvement in the raising of a
2013 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002079What's New in Python 2.6 beta 3?
2080================================
2081
Barry Warsaw07a4a382008-08-21 01:15:08 +00002082*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002083
2084Core and Builtins
2085-----------------
2086
Guido van Rossumf8402962008-08-20 15:01:50 +00002087- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2088 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2089 extensions do not automatically benefit from the class attribute
2090 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2091 to their tp_flags field if they care. This is a backwards
2092 compatibility feature; in 3.0, all types will use the cache by
2093 default.
2094
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002095- Keyword arguments can now follow starred arguments. (``f(a, *args,
2096 keyword=23)`` is now valid syntax.)
2097
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002098- ctypes function pointers that are COM methods have a boolean True
2099 value again.
2100
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002101- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2102 by denying s# to parse objects that have a releasebuffer procedure,
2103 and introducing s*.
2104
Georg Brandl1e13ea92008-08-11 09:07:59 +00002105- Issue #3537: Fix an assertion failure when an empty but presized dict
2106 object was stored in the freelist.
2107
Mark Dickinsonb6467572008-08-04 21:30:09 +00002108- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2109 ValueError consistently across platforms.
2110
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002111- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2112 (64bit Unix, for example), unichr() would truncate its argument and return
2113 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2114
Neal Norwitze7d8be82008-07-31 17:17:14 +00002115- Apply security patches from Apple.
2116
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002117- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2118 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2119
Antoine Pitrou92f82162008-07-25 22:22:08 +00002120- Issue #1819: function calls with several named parameters are now on
2121 average 35% faster (as measured by pybench).
2122
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002123- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2124 the python debugger steps into a class statement: the free variables (local
2125 variables defined in an outer scope) would be deleted from the outer scope.
2126
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002127- Issue #2620: Overflow checking when allocating or reallocating memory
2128 was not always being done properly in some python types and extension
2129 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2130 all been updated to perform better checks and places in the code that
2131 would previously leak memory on the error path when such an allocation
2132 failed have been fixed.
2133
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002134Library
2135-------
2136

2138
Benjamin Petersone977ad42008-08-20 01:42:01 +00002139- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2140 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2141
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002142- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2143 version reported by these tools does not necessarily follow the python
2144 version numbering scheme, so the module is less strict when parsing it.
2145
Nick Coghlanf70385a2008-08-18 12:42:46 +00002146- Issue #2235: Added Py3k warnings for types which will become unhashable
2147 under the stricter __hash__ inheritance rules in 3.0. Several types
2148 which did not meet the rules for hash invariants and were already
2149 unhashable in 3.0 have now been explicitly flagged as unhashable in
2150 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2151 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2152
Brett Cannon88f801d2008-08-18 00:46:22 +00002153- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2161
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002162- Issue #3575: Incremental decoder's decode function now takes bytearray
2163 by using 's*' instead of 't#'.
2164
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002165- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002166 fails unicode conversion on 2nd parameter. (windows only)
2167
Facundo Batista94f243a2008-08-17 03:38:39 +00002168- Issue 2464. urllib2 now supports a malformation in the URL received
2169 in a redirect.
2170
Brett Cannonabe423e2008-08-16 21:47:07 +00002171- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002172 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002173
Facundo Batistaeb90b782008-08-16 14:44:07 +00002174- Issue #2776: fixed small issue when handling an URL with double slash
2175 after a 302 response in the case of not going through a proxy.
2176
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002177- Issue #2676: in the email package, content-type parsing was hanging on
2178 pathological input because of quadratic or exponential behaviour of a
2179 regular expression.
2180
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002181- Issue #3476: binary buffered reading through the new "io" library is now
2182 thread-safe.
2183
Brett Cannonbf3157b2008-08-14 05:00:03 +00002184- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2185 since mimetools itself is deprecated. Because modules are cached, all
2186 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2187
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002188- Issue #3134: shutil referenced undefined WindowsError symbol.
2189
Robert Schuppenies14646332008-08-10 11:01:53 +00002190- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2191 menu entries were not deleted.
2192
Brett Cannon83e81842008-08-09 23:30:55 +00002193- Copied the implementation of reduce() to _functools.reduce() to have a
2194 version that did not raise a DeprecationWarning under -3.
2195
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002196- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2197 a MemoryError rather than silently stop the iteration.
2198
Guido van Rossum59ce9012008-08-09 14:55:34 +00002199- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2200 to _sre.compile() will now be rejected. This should not affect anybody
2201 since the re.compile() function never generates invalid re-bytecode.
2202
Skip Montanaroa032bf42008-08-08 22:52:51 +00002203- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00002222 asking for a specific length. This problem only affected files opened
2223 using the new "io" module, not the built-in open() function.

Mark Dickinson64b7e502008-07-16 09:40:03 +00002285- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2286 produced a ValueError instead of giving the correct float.
2287
Eric Smitha5fa5a22008-07-16 00:11:49 +00002288- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2289 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2290
Mark Dickinson7103aa42008-07-15 19:08:33 +00002291- Issue #3008: the float type has a new instance method 'float.hex'
2292 and a new class method 'float.fromhex' to convert floating-point
2293 numbers to and from hexadecimal strings, respectively.
2294
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002295- Issue #2235: __hash__ is once again inherited by default. To allow
2296 collections.Hashable to remain meaningful in the presence of the
2297 default hash implementation (object.__hash__), it is now possible
2298 to explicit block inheritance of hash by setting __hash__=None at
2299 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2300 level.
2301
Nick Coghlanb028f502008-07-13 14:52:36 +00002302- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2303 the parent module cannot be found while performing an absolute import.
2304 This means that an incorrectly defined __package__ attribute will
2305 now only prevent relative imports in that module rather than causing
2306 all imports from that module to fail.
2307
Nick Coghlan14ff9942008-07-08 14:21:42 +00002308- Issue #2517: Allow unicode messages in Exceptions again by correctly

2319
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002320- Issue #3004: Minor change to slice.indices(): the start and stop
2321 arguments are now treated identically, making the behaviour easier
2322 to describe and understand. For example, slice(None, -10,
2323 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2324 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2325 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00002327- Issue #3219: Calling a function with repeated keyword arguments,
2328 f(a=2, a=23), would not cause a syntax error. This was a regression
2329 from 2.4 caused by the switch to the new compiler.

2368 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002369 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00002841- Issue #1631171: Re-implement the 'warnings' module in C (the
2842 original Python code has been kept as backup). This will allow for
2843 using the 'warning's machinery in such places as the parser where
2844 use of pure Python code is not possible. Both the ``showarning()``
2845 and ``formatwarning()`` gain an optional 'line' argument which is
2846 not called by default for backwards-compatibility reasons. Setting
2847 ``warnings.showwarning()`` to an implementation that lacks support
2848 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002911- Issue #2550: The approach used by client/server code for obtaining
2912 ports to listen on in network-oriented tests has been refined in an
2913 effort to facilitate running multiple instances of the entire
2914 regression test suite in parallel without issue.
2915 test_support.bind_port() has been fixed such that it will always
2916 return a unique port -- which wasn't always the case with the
2917 previous implementation, especially if socket options had been set
2918 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2919 new implementation of bind_port() will actually raise an exception
2920 if it is passed an AF_INET/SOCK_STREAM socket with either the
2921 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2922 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2923 the socket it's been passed. This currently only applies to
2924 Windows. This option prevents any other sockets from binding to the
2925 host/port we've bound to, thus removing the possibility of the
2926 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2927 when a second SOCK_STREAM socket binds and accepts to a host/port
2928 that's already been bound by another socket. The optional preferred
2929 port parameter to bind_port() has been removed. Under no
2930 circumstances should tests be hard coding ports!
2931
2932 test_support.find_unused_port() has also been introduced, which will
2933 pass a temporary socket object to bind_port() in order to obtain an
2934 unused port. The temporary socket object is then closed and
2935 deleted, and the port is returned. This method should only be used
2936 for obtaining an unused port in order to pass to an external program
2937 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2938 a parameter to a server-oriented class that doesn't give you direct
2939 access to the underlying socket used.
2940
2941 Finally, test_support.HOST has been introduced, which should be used
2942 for the host argument of any relevant socket calls (i.e. bind and
2943 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002944
2945 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002946 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002947 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2948 test_asynchat and test_socket_ssl.
2949
Georg Brandl3ee81df2008-05-17 18:14:43 +00002950 It is now possible for multiple instances of the regression test
2951 suite to run in parallel without issue.

3218-----------------
3219
Fred Drakea8ee94b2008-03-01 02:45:07 +00003220- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003221 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003222
Georg Brandlad61bc82008-02-23 15:11:18 +00003223- Issue #2067: file.__exit__() now calls subclasses' close() method.
3224
3225- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003226
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003227- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003228 issue 215555 for a discussion.
3229
Eric Smitha73fbe72008-02-23 03:09:44 +00003230- Added the future_builtins module, which contains hex() and oct().
3231 These are the PEP 3127 version of these functions, designed to be
3232 compatible with the hex() and oct() builtins from Python 3.0. They
3233 differ slightly in their output formats from the existing, unchanged
3234 Python 2.6 builtins. The expected usage of the future_builtins
3235 module is:
3236 from future_builtins import hex, oct
3237
Eric Smith7ef40bf2008-02-20 23:34:22 +00003238- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3239 exponents for exponents with absolute value < 100. Follows C99
3240 standard. This is a change on Windows, which would use 3 digits.
3241 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3242 so that any alterations it does to the resulting string will be
3243 available in stringlib/formatter.h (for float.__format__).
3244
Eric Smith5a3c1352008-02-19 13:21:56 +00003245- Implemented PEP 3101, Advanced String Formatting. This adds a new
3246 builtin format(); a format() method for str and unicode; a
3247 __format__() method to object, str, unicode, int, long, float, and
3248 datetime; the class string.Formatter; and the C API
3249 PyObject_Format().
3250
Georg Brandl3ee81df2008-05-17 18:14:43 +00003251- Fixed several potential crashes, all caused by specially crafted
3252 __del__ methods exploiting objects in temporarily inconsistent
3253 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003254
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003255- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003256 prevent a possible crash: an Abstract Base Class would try to access
3257 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003258
Georg Brandl3ee81df2008-05-17 18:14:43 +00003259- Fixed repr() and str() of complex numbers with infinity or nan as
3260 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003261
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262- Clear all free lists during a gc.collect() of the highest generation
3263 in order to allow pymalloc to free more arenas. Python may give back
3264 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003265
Georg Brandl3ee81df2008-05-17 18:14:43 +00003266- Issue #2045: Fix an infinite recursion triggered when printing a
3267 subclass of collections.defaultdict, if its default_factory is set
3268 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003269
Christian Heimesf75dbef2008-02-08 00:11:31 +00003270- Fixed a minor memory leak in dictobject.c. The content of the free
3271 list was not freed on interpreter shutdown.
3272
Georg Brandl3ee81df2008-05-17 18:14:43 +00003273- Limit free list of method and builtin function objects to 256
3274 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003275
Georg Brandl3ee81df2008-05-17 18:14:43 +00003276- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3277 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003278 to compact the internal free lists of pre-allocted ints and floats.
3279
Georg Brandl3ee81df2008-05-17 18:14:43 +00003280- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3281 calls. Python expected the return type int but the fork familie
3282 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3285 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003286
Georg Brandl3ee81df2008-05-17 18:14:43 +00003287- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3288 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003289

3294 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003295
Georg Brandl3ee81df2008-05-17 18:14:43 +00003296- Patch #1473257: generator objects gain a gi_code attribute. This is
3297 the same object as the func_code attribute of the function that
3298 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003299
Georg Brandl3ee81df2008-05-17 18:14:43 +00003300- Issue #1920: "while 0" statements were completely removed by the
3301 compiler, even in the presence of an "else" clause, which is
3302 supposed to be run when the condition is false. Now the compiler
3303 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003304
Guido van Rossumeead05f2008-01-24 18:21:02 +00003305- A few crashers fixed: weakref_in_del.py (issue #1377858);
3306 loosing_dict_ref.py (issue #1303614, test67.py);
3307 borrowed_ref_[34].py (not in tracker).
3308
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003309- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003310 suppressed while an extension is loaded by calling SetErrorMode in
3311 dynload_win.c. The error is still reported properly.
3312
Georg Brandl3ee81df2008-05-17 18:14:43 +00003313- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003314 several extension methods and modules do not work without unicode
3315 support.
3316
Georg Brandl26543b12008-01-21 18:36:51 +00003317- Issue #1882: when compiling code from a string, encoding cookies in the
3318 second line of code were not always recognized correctly.
3319
Georg Brandl14404b62008-01-19 19:27:05 +00003320- Issue #1679: "0x" was taken as a valid integer literal.
3321
Georg Brandl6caad7d2008-01-26 14:19:22 +00003322- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003323 added.
3324
Christian Heimesc94e2b52008-01-14 04:13:37 +00003325- sys.float_info / PyFloat_GetInfo: The floating point information
3326 object was converted from a dict to a specialized structseq object.
3327
Georg Brandl3ee81df2008-05-17 18:14:43 +00003328- Patch #1816: Added sys.flags structseq. It exposes the status of
3329 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003330
Georg Brandl3ee81df2008-05-17 18:14:43 +00003331- Objects/structseq.c: Implemented new structseq representation. The
3332 patch makes structseqs (e.g. the return value of os.stat) more
3333 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003334
Georg Brandl3ee81df2008-05-17 18:14:43 +00003335- Patch #1700288: added a type attribute cache that caches method
3336 accesses, resulting in speedups in heavily object-oriented code.

3345 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003346
Georg Brandl3ee81df2008-05-17 18:14:43 +00003347- Improve some exception messages when Windows fails to load an
3348 extension module. Now we get for example '%1 is not a valid Win32
3349 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003350

Georg Brandl3ee81df2008-05-17 18:14:43 +00003360- Compiler now generates simpler and faster code for dictionary
3361 literals. The oparg for BUILD_MAP now indicates an estimated
3362 dictionary size. There is a new opcode, STORE_MAP, for adding
3363 entries to the dictionary.

3406
Georg Brandl3ee81df2008-05-17 18:14:43 +00003407- The enumerate() builtin function is no longer bounded to sequences
3408 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3409 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003410
Georg Brandl3ee81df2008-05-17 18:14:43 +00003411- Issue #1686386: Tuple's tp_repr did not take into account the
3412 possibility of having a self-referential tuple, which is possible
3413 from C code. Nor did object's tp_str consider that a type's tp_str
3414 could do something that could lead to an inifinite recursion.
3415 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3416 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003417
Georg Brandl3ee81df2008-05-17 18:14:43 +00003418- Issue #1164: It was possible to trigger deadlock when using the
3419 'print' statement to write to a file since the GIL was not released
3420 as needed. Now PyObject_Print() does the right thing along with
3421 various tp_print implementations of the built-in types and those in
3422 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00003431- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003432 PyObject_Call() never calling back out to Python code to trigger
3433 recursion depth updates/checks. Required the creation of a static
3434 RuntimeError instance in case normalizing an exception put the
3435 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00003451- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003452 __*__ attributes. (Some already existed, e.g., __doc__ and
3453 __name__.)

3460
Collin Winter62903052007-05-18 23:11:24 +00003461- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003462 "except E as target:". This is to provide forwards compatibility
3463 with Python 3.0.

3469
Vinay Sajip8549ce32007-05-06 17:53:37 +00003470- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003471 setting a plain string, ie don't expand to single letter identifiers.
3472
Raymond Hettinger13936692007-04-11 18:40:58 +00003473- Request #1191699: Slices can now be pickled.

3477 remaining characters.
3478
Georg Brandl5cb76c12007-03-21 09:00:39 +00003479- Patch #1682205: a TypeError while unpacking an iterable is no longer

3483
Guido van Rossum143b5642007-03-23 04:58:42 +00003484- Bug #1683368: The object.__init__() and object.__new__() methods are
3485 now stricter in rejecting excess arguments. The only time when
3486 either allows excess arguments is when it is not overridden and the
3487 other one is. For backwards compatibility, when both are
3488 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003489 warning later). Also, type.__init__() insists on the same signature
3490 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003491
Georg Brandl3ee81df2008-05-17 18:14:43 +00003492- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3493 object to complex using its __complex__() method before falling back
3494 to the __float__() method. Therefore, the functions in the cmath
3495 module now can operate on objects that define a __complex__()
3496 method.

3513
Georg Brandl7b9c5552007-03-12 14:30:05 +00003514- Bug #1678647: write a newline after printing an exception in any
3515 case, even when converting the value to a string failed.
3516
Georg Brandl871f1bc2007-03-12 13:17:36 +00003517- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003518 its argument, if it exists. If not, it will work like before. This
3519 allows customizing the output of dir() in the presence of a
3520 __getattr__().

3524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Patch #1675981: remove unreachable code from ``type.__new__()``

3529 parthensized forms. This means complex(repr(x)) now works instead of
3530 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003531
Georg Brandlaa2321b2007-03-07 00:40:28 +00003532- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003533 makes the filenames the warning module prints much more sensible
3534 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003547- Patch #1674228: when assigning a slice (old-style), check for the
3548 sq_ass_slice instead of the sq_slice slot.
3549
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550- When printing an unraisable error, don't print exceptions. before

Georg Brandl4e933132006-09-06 20:05:58 +00003635- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003653 generator expressions (x for x, in ... ) works again. Fixing this
3654 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00003694- Removed uses of dict.has_key() from distutils, and uses of
3695 callable() from copy_reg.py, so the interpreter now starts up

Georg Brandl3ee81df2008-05-17 18:14:43 +00004103- Patch #1530482: add pydoc.render_doc() which returns the

4118
Georg Brandl92a6bae2007-03-13 17:43:32 +00004119- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004120 are set for invalid interpolation sequences that would lead to
4121 errors on reading back those values.

4177 TestCase and TestSuite subclasses (not instances) are no longer
4178 accepted in TestSuite.addTest(). This should cause no
4179 incompatibility since it never made sense with ordinary subclasses
4180 -- the failure just occurred later, with a more cumbersome
4181 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004468 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004569- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004570 time so that opening a database previously created with the DB_DUP
4571 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4572 opens. Specifically: dictionary assignment to a DB object will
4573 replace all values for a given key when the database allows
4574 duplicate values. DB users should use DB.put(k, v) when they want
4575 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004576

4583 dots only if they occur on a single line, as opposed to the previous
4584 behavior of quoting dots if they are the second character of any
4585 line.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004854- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004855 periodic threadstate and signal checking in tight loops. By
4856 default, this option is turned-off. It should only be enabled in
4857 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00004914
Georg Brandl3ee81df2008-05-17 18:14:43 +00004915- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4916 to ``PyTuple_SetItem``, it can be used to populate a brand new

4929
Georg Brandl3ee81df2008-05-17 18:14:43 +00004930- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4931 of w# format code incorrectly truncated the length to an int, even
4932 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4933 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004963- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4964 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004965

Georg Brandl3ee81df2008-05-17 18:14:43 +00004991- Removed the macfs module. It had been deprecated since Python 2.5.
4992 This lead to the deprecation of macostools.touched() as it relied
4993 solely on macfs and was a no-op under OS X.
