Benjamin Petersonddd392c2009-12-13 19:19:07 +000027- Issue #7349: Make methods of file objects in the io module accept None as an
28 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
29 the same as passing no argument.
30
Benjamin Petersonc4771d22009-12-13 17:31:31 +000031- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000064- Issue #7419: setlocale() could crash the interpreter on Windows when called
65 with invalid values.
66
Eric Smithc4ab8332009-11-29 17:40:57 +000067- Issue #3382: 'F' formatting for float and complex now convert the
68 result to upper case. This only affects 'inf' and 'nan', since 'f'
69 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000070
Mark Dickinson9dd5e162009-11-23 20:54:09 +000071- Remove switch from "%f" formatting to "%g" formatting for floats
72 larger than 1e50 in absolute value.
73
Mark Dickinson18cfada2009-11-23 18:46:41 +000074- Remove restrictions on precision when formatting floats. E.g.,
75 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
76 requested 120 significant digits instead.
77
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000078- Add Py3k warnings for parameter names in parenthesis.
79
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000080- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000081
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000082- Issue #7085: Fix crash when importing some extensions in a thread
83 on MacOSX 10.6.
84
Mark Dickinsonb678de82009-11-19 18:41:49 +000085- Issue #7117: repr(x) for a float x returns a result based on the
86 shortest decimal string that's guaranteed to round back to x under
87 correct rounding (with round-half-to-even rounding mode).
88 Previously it gave a string based on rounding x to 17 decimal digits.
89 repr(x) for a complex number behaves similarly. On platforms where
90 the correctly-rounded strtod and dtoa code is not supported (see below),
91 repr is unchanged.
92
93- Issue #7117: On almost all platforms: float-to-string and
94 string-to-float conversions within Python are now correctly rounded.
95 Places these conversions occur include: str for floats and complex
96 numbers; the float and complex constructors; old-style and new-style
97 numeric formatting; serialization and deserialization of floats and
98 complex numbers using marshal, pickle and json; parsing of float and
99 imaginary literals in Python code; Decimal-to-float conversion.
100
101 The conversions use a Python-adapted version of David Gay's
102 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
103 functions. This code is supported on Windows, and on Unix-like
104 platforms using gcc, icc or suncc as the C compiler. There may be a
105 small number of platforms on which correct operation of this code
106 cannot be guaranteed, so the code is not used: notably, this applies
107 to platforms where the C double format is not IEEE 754 binary64, and
108 to platforms on x86 hardware where the x87 FPU is set to 64-bit
109 precision and Python's configure script is unable to determine how
110 to change the FPU precision. On these platforms conversions use the
111 platform strtod and dtoa, as before.
112
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000113- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000114 now uses the correctly-rounded string <-> float conversions
115 described above (when available), and so produces correctly rounded
116 results that will display nicely under the float repr. There are
117 two related small changes: (1) round now accepts any class with an
118 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000119 floats for the second argument), and (2) an excessively large second
120 integer argument (e.g., round(1.234, 10**100)) no longer raises an
121 exception.
122
Philip Jenveyfab8be22009-11-17 02:42:26 +0000123- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
124
Benjamin Petersone36199b2009-11-12 23:39:44 +0000125- Fix several issues with compile(). The input can now contain Windows and Mac
126 newlines and is no longer required to end in a newline.
127
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000128- Remove length limitation when constructing a complex number from a
129 unicode string.
130
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000131- Issue #7244: itertools.izip_longest() no longer ignores exceptions
132 raised during the formation of an output tuple.
133

135
Antoine Pitrouefb60c02009-10-20 21:29:37 +0000136- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
137 fixes the problem of some exceptions being thrown at shutdown when the
138 interpreter is killed. Patch by Adam Olsen.
139
Eric Smithc12781a2009-10-19 14:38:14 +0000140- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

144 crash in GAE.
145
Benjamin Peterson196b0922009-10-15 15:44:46 +0000146- Issue #7140: The __dict__ of a module should not be cleared unless the module
147 is the only object holding a reference to it.
148
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000149- Issue #1754094: Improve the stack depth calculation in the compiler.
150 There should be no other effect than a small decrease in memory use.
151 Patch by Christopher Tur Lesniewski-Laas.
152
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000153- Issue #7084: Fix a (very unlikely) crash when printing a list from one
154 thread, and mutating it from another one. Patch by Scott Dial.
155
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000156- Issue #1571184: The Unicode database contains properties for more characters.

169 of producing internally inconsistent Python longs.
170
Philip Jenveydbf3b252009-09-29 04:32:44 +0000171- Issue #6990: Fix threading.local subclasses leaving old state around

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000263- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
264 (1) inf and nan strings with trailing whitespace were incorrectly
265 rejected; (2) parsing of strings representing infinities and nans
266 was locale aware; and (3) the interpretation of fromhex('-nan')
267 didn't match that of float('-nan').
268
Eric Smitha985a3a2009-05-05 18:26:08 +0000269- Issue #5920: For float.__format__, change the behavior with the
270 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
271 to be like 'g' but with at least one decimal point and with a
272 default precision of 12. Previously, the behavior the same but with
273 a default precision of 6. This more closely matches str(), and
274 reduces surprises when adding alignment flags to the empty
275 presentation type. This also affects the new complex.__format__ in
276 the same way.
277
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000278- Issue #5890: in subclasses of 'property' the __doc__ attribute was

303 z involves nans, infs or negative zeros.
304
Eric Smithaca19e62009-04-22 13:29:05 +0000305- Implement PEP 378, Format Specifier for Thousands Separator, for
306 floats, ints, and longs.
307
308- Issue #5515: 'n' formatting for ints, longs, and floats handles
309 leading zero formatting poorly.

339
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000340- Issue #4688: Add a heuristic so that tuples and dicts containing only
341 untrackable objects are not tracked by the garbage collector. This can
342 reduce the size of collections and therefore the garbage collection overhead
343 on long-running programs, depending on their particular use of datatypes.

348
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000349- Issue #4258: Make it possible to use base 2**30 instead of base
350 2**15 for the internal representation of integers, for performance
351 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
352 --enable-big-digits option to configure, which overrides the
353 default. Add sys.long_info structseq to provide information about
354 the internal format.
355
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000356- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

378 on a 64-bit system.
379
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000380- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

387
Georg Brandl29c6a282009-04-05 20:23:13 +0000388- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000389 were suppressing all exceptions. These include list(), filter(), map(),
390 zip(), and bytearray().
391
Benjamin Peterson596d3062009-01-19 15:42:23 +0000392- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

401 to str, bytes and bytearray could be optimized away by the compiler, letting
402 the interpreter segfault instead of raising an error.
403

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000411- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
412 collecting the oldest generation) so that allocating lots of objects without
413 destroying them does not show quadratic performance. Based on a proposal by

Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000419- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
420 an existing .py counterpart, override the co_filename attributes of all
421 code objects if the original filename is obsolete (which can happen if the
422 file has been renamed, moved, or if it is accessed through different paths).
423 Patch by Ziga Seilnacht and Jean-Paul Calderone.

435
Benjamin Peterson7af65562008-12-29 17:56:58 +0000436- Issue #4764: With io.open, IOError.filename is set when trying to open a

444
Skip Montanarof205c132008-12-23 03:30:15 +0000445- Added test case to ensure attempts to read from a file opened for writing
446 fail.
447
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000448- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

461 exceptions.
462
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000463- Issue #4445: Replace "sizeof(PyStringObject)" with
464 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
465 str instances. On a typical machine this saves 3 bytes of memory
466 (on average) per string allocation.
467
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000468- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
469 interpreter to abort ("Fatal Python error: Could not reset the stack!")
470 instead of throwing a MemoryError.
471
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000472- Issue #3689: The list reversed iterator now supports __length_hint__

474
Benjamin Petersonc078f922008-11-21 22:27:24 +0000475- Issue #4367: Python would segfault during compiling when the unicodedata

477
Vinay Sajip213faca2008-12-03 23:22:58 +0000478- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000479 method on file objects with closefd=False. The file descriptor is still
480 kept open but the file object behaves like a closed file. The ``FileIO``
481 object also got a new readonly attribute ``closefd``.
482
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000483- Issue #4348: Some bytearray methods returned that didn't cause any change to

497
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000498- Issue #4209: Enabling unicode_literals and the print_function in the same
499 __future__ import didn't work.
500
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000501- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000502 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000504- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
505 returned a path longer than MAX_PATH. (But It's doubtful this code path is
506 really executed because I cannot move to such directory on win2k)
507
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000508- Issue #4069: When set.remove(element) is used with a set element, the element
509 is temporarily replaced with an equivalent frozenset. But the eventual
510 KeyError would always report the empty frozenset([]) as the missing key. Now
511 it correctly refers to the initial element.

530
Walter Dörwalded960ac2009-05-03 22:36:33 +0000531- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
532 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
533 step. This avoids problems with counting UTF-8 bytes that ignores the effect
534 of using the replace error handler in PyUnicode_DecodeUTF8().
535
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000536- Issue #3739: The unicode-internal encoder now reports the number of characters
537 consumed like any other encoder (instead of the number of bytes).
538
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000539- Issue #2422: When compiled with the ``--with-valgrind`` option, the
540 pymalloc allocator will be automatically disabled when running under
541 Valgrind. This gives improved memory leak detection when running
542 under Valgrind, while taking advantage of pymalloc at other times.

1718 - Packing a float now always gives a Deprecation Warning.
1719 Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
1720
1721 - If x is not an int, long or float, then packing x will always
1722 result in struct.error. Previously an x with an __int__ method
1723 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1724 ,'*i', '*l', and an x with a __long__ method could be packed by
1725 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
1726 TypeError used to be raised (with a confusing error message) for
1727 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001921- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1922 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1923 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1924 ``printf`` function, whereas PyString_FromFormat has an independent
1925 implementation and uses "%zd" on all platforms for size_t values.
1926 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitrou0668c622008-08-26 22:42:08 +00001947 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1948 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1949 when given a tuple of classes as second argument, were looking up
1950 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1951 type object.

2022 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2023 for catch_warnings() also led to an improvement in the raising of a
2024 DeprecationWarning related to warnings.warn_explicit().

2048
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002049- Issue #2975: When compiling several extension modules with Visual Studio 2008

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002090What's New in Python 2.6 beta 3?
2091================================
2092
Barry Warsaw07a4a382008-08-21 01:15:08 +00002093*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002094
2095Core and Builtins
2096-----------------
2097
Guido van Rossumf8402962008-08-20 15:01:50 +00002098- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2099 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2100 extensions do not automatically benefit from the class attribute
2101 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2102 to their tp_flags field if they care. This is a backwards
2103 compatibility feature; in 3.0, all types will use the cache by
2104 default.
2105
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002106- Keyword arguments can now follow starred arguments. (``f(a, *args,
2107 keyword=23)`` is now valid syntax.)
2108
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002109- ctypes function pointers that are COM methods have a boolean True
2110 value again.
2111
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002112- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2113 by denying s# to parse objects that have a releasebuffer procedure,
2114 and introducing s*.
2115
Georg Brandl1e13ea92008-08-11 09:07:59 +00002116- Issue #3537: Fix an assertion failure when an empty but presized dict
2117 object was stored in the freelist.
2118
Mark Dickinsonb6467572008-08-04 21:30:09 +00002119- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2120 ValueError consistently across platforms.
2121
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002122- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2123 (64bit Unix, for example), unichr() would truncate its argument and return
2124 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2125
Neal Norwitze7d8be82008-07-31 17:17:14 +00002126- Apply security patches from Apple.
2127
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002128- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2129 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2130
Antoine Pitrou92f82162008-07-25 22:22:08 +00002131- Issue #1819: function calls with several named parameters are now on
2132 average 35% faster (as measured by pybench).
2133
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002134- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2135 the python debugger steps into a class statement: the free variables (local
2136 variables defined in an outer scope) would be deleted from the outer scope.
2137
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002138- Issue #2620: Overflow checking when allocating or reallocating memory
2139 was not always being done properly in some python types and extension
2140 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2141 all been updated to perform better checks and places in the code that
2142 would previously leak memory on the error path when such an allocation
2143 failed have been fixed.
2144
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002145Library
2146-------
2147

2149
Benjamin Petersone977ad42008-08-20 01:42:01 +00002150- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2151 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2152
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002153- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2154 version reported by these tools does not necessarily follow the python
2155 version numbering scheme, so the module is less strict when parsing it.
2156
Nick Coghlanf70385a2008-08-18 12:42:46 +00002157- Issue #2235: Added Py3k warnings for types which will become unhashable
2158 under the stricter __hash__ inheritance rules in 3.0. Several types
2159 which did not meet the rules for hash invariants and were already
2160 unhashable in 3.0 have now been explicitly flagged as unhashable in
2161 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2162 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2163
Brett Cannon88f801d2008-08-18 00:46:22 +00002164- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2172
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002173- Issue #3575: Incremental decoder's decode function now takes bytearray
2174 by using 's*' instead of 't#'.
2175
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002176- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002177 fails unicode conversion on 2nd parameter. (windows only)
2178
Facundo Batista94f243a2008-08-17 03:38:39 +00002179- Issue 2464. urllib2 now supports a malformation in the URL received
2180 in a redirect.
2181
Brett Cannonabe423e2008-08-16 21:47:07 +00002182- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002183 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002184
Facundo Batistaeb90b782008-08-16 14:44:07 +00002185- Issue #2776: fixed small issue when handling an URL with double slash
2186 after a 302 response in the case of not going through a proxy.
2187
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002188- Issue #2676: in the email package, content-type parsing was hanging on
2189 pathological input because of quadratic or exponential behaviour of a
2190 regular expression.
2191
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002192- Issue #3476: binary buffered reading through the new "io" library is now
2193 thread-safe.
2194
Brett Cannonbf3157b2008-08-14 05:00:03 +00002195- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2196 since mimetools itself is deprecated. Because modules are cached, all
2197 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2198
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002199- Issue #3134: shutil referenced undefined WindowsError symbol.
2200
Robert Schuppenies14646332008-08-10 11:01:53 +00002201- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2202 menu entries were not deleted.
2203
Brett Cannon83e81842008-08-09 23:30:55 +00002204- Copied the implementation of reduce() to _functools.reduce() to have a
2205 version that did not raise a DeprecationWarning under -3.
2206
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002207- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2208 a MemoryError rather than silently stop the iteration.
2209
Guido van Rossum59ce9012008-08-09 14:55:34 +00002210- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2211 to _sre.compile() will now be rejected. This should not affect anybody
2212 since the re.compile() function never generates invalid re-bytecode.
2213
Skip Montanaroa032bf42008-08-08 22:52:51 +00002214- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00002233 asking for a specific length. This problem only affected files opened
2234 using the new "io" module, not the built-in open() function.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002289Core and Builtins
2290-----------------
2291
Georg Brandl3e483f62008-07-16 22:57:41 +00002292- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2293 its methods now allow for items objects that can be converted to
2294 an integer using operator.index().
2295
Mark Dickinson64b7e502008-07-16 09:40:03 +00002296- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2297 produced a ValueError instead of giving the correct float.
2298
Eric Smitha5fa5a22008-07-16 00:11:49 +00002299- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2300 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2301
Mark Dickinson7103aa42008-07-15 19:08:33 +00002302- Issue #3008: the float type has a new instance method 'float.hex'
2303 and a new class method 'float.fromhex' to convert floating-point
2304 numbers to and from hexadecimal strings, respectively.
2305
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002306- Issue #2235: __hash__ is once again inherited by default. To allow
2307 collections.Hashable to remain meaningful in the presence of the
2308 default hash implementation (object.__hash__), it is now possible
2309 to explicit block inheritance of hash by setting __hash__=None at
2310 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2311 level.
2312
Nick Coghlanb028f502008-07-13 14:52:36 +00002313- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2314 the parent module cannot be found while performing an absolute import.
2315 This means that an incorrectly defined __package__ attribute will
2316 now only prevent relative imports in that module rather than causing
2317 all imports from that module to fail.
2318
Nick Coghlan14ff9942008-07-08 14:21:42 +00002319- Issue #2517: Allow unicode messages in Exceptions again by correctly
2320 bypassing the instance dictionary when looking up __unicode__ on
2321 new-style classes.
2322
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002323- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2324 set to a custom object whose write() method happens to install
2325 another file in sys.stdout.
2326
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002327- Issue #3088: Corrected a race condition in classes derived from
2328 threading.local: the first member set by a thread could be saved in
2329 another thread's dictionary.
2330
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002331- Issue #3004: Minor change to slice.indices(): the start and stop
2332 arguments are now treated identically, making the behaviour easier
2333 to describe and understand. For example, slice(None, -10,
2334 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2335 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2336 10, -1).
2337
Georg Brandl278fc502008-07-19 12:46:12 +00002338- Issue #3219: Calling a function with repeated keyword arguments,
2339 f(a=2, a=23), would not cause a syntax error. This was a regression
2340 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002341
Georg Brandl278fc502008-07-19 12:46:12 +00002342- Issue #2862: Make int and float freelist management consistent with
2343 other freelists. Changes their CompactFreeList apis into
2344 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002345
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002346Library
2347-------
2348
Thomas Heller57adf222008-08-14 19:10:48 +00002349- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2350 api functions without holding the GIL, which could lead to a fatal
2351 error when they failed.
2352
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002353- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
2354
Jesse Noller7fb96402008-07-17 21:01:05 +00002355- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

2360
Jesse Noller13e9d582008-07-16 14:32:36 +00002361- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2362 ForkingPickler.register() to resolve conflict with ctypes.
2363
Vinay Sajip51e65192008-07-18 09:01:10 +00002364- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002365
Thomas Heller880f5292008-07-15 19:39:38 +00002366- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2367 a valid dlerror() message.
2368
Thomas Heller2bad6572008-07-15 17:19:50 +00002369- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2370 incomplete structure was created.
2371
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002372- Issue #3339: dummy_thread.acquire() should not return None.
2373
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002374- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2375
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002376- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002377
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002378- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2379 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002380 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002381 content-length. The problem had been corrected in the 2.4 branch, but never
2382 merged into trunk.
2383
Georg Brandle78fbcc2008-07-05 10:13:36 +00002384- Issue #2663: add filtering capability to shutil.copytree().

2387
2388- Issue #1526: Allow more than 64k files to be added to Zip64 file.
2389
2390- Issue #1746: Correct handling of zipfile archive comments (previously
2391 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002392 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002393
Vinay Sajip51e65192008-07-18 09:01:10 +00002394- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002395 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002396
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002397- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2398 handling is now the same as that of other special attributes like __name__).
2399
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002400- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2401 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002852- Issue #1631171: Re-implement the 'warnings' module in C (the
2853 original Python code has been kept as backup). This will allow for
2854 using the 'warning's machinery in such places as the parser where
2855 use of pure Python code is not possible. Both the ``showarning()``
2856 and ``formatwarning()`` gain an optional 'line' argument which is
2857 not called by default for backwards-compatibility reasons. Setting
2858 ``warnings.showwarning()`` to an implementation that lacks support
2859 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002922- Issue #2550: The approach used by client/server code for obtaining
2923 ports to listen on in network-oriented tests has been refined in an
2924 effort to facilitate running multiple instances of the entire
2925 regression test suite in parallel without issue.
2926 test_support.bind_port() has been fixed such that it will always
2927 return a unique port -- which wasn't always the case with the
2928 previous implementation, especially if socket options had been set
2929 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2930 new implementation of bind_port() will actually raise an exception
2931 if it is passed an AF_INET/SOCK_STREAM socket with either the
2932 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2933 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2934 the socket it's been passed. This currently only applies to
2935 Windows. This option prevents any other sockets from binding to the
2936 host/port we've bound to, thus removing the possibility of the
2937 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2938 when a second SOCK_STREAM socket binds and accepts to a host/port
2939 that's already been bound by another socket. The optional preferred
2940 port parameter to bind_port() has been removed. Under no
2941 circumstances should tests be hard coding ports!
2942
2943 test_support.find_unused_port() has also been introduced, which will
2944 pass a temporary socket object to bind_port() in order to obtain an
2945 unused port. The temporary socket object is then closed and
2946 deleted, and the port is returned. This method should only be used
2947 for obtaining an unused port in order to pass to an external program
2948 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2949 a parameter to a server-oriented class that doesn't give you direct
2950 access to the underlying socket used.
2951
2952 Finally, test_support.HOST has been introduced, which should be used
2953 for the host argument of any relevant socket calls (i.e. bind and
2954 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002955
2956 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002957 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002958 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2959 test_asynchat and test_socket_ssl.
2960
Georg Brandl3ee81df2008-05-17 18:14:43 +00002961 It is now possible for multiple instances of the regression test
2962 suite to run in parallel without issue.

3229-----------------
3230
Fred Drakea8ee94b2008-03-01 02:45:07 +00003231- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003232 644. The mode is now inherited from the py file.

3235
3236- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003237
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003238- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003239 issue 215555 for a discussion.
3240
Eric Smitha73fbe72008-02-23 03:09:44 +00003241- Added the future_builtins module, which contains hex() and oct().
3242 These are the PEP 3127 version of these functions, designed to be
3243 compatible with the hex() and oct() builtins from Python 3.0. They
3244 differ slightly in their output formats from the existing, unchanged
3245 Python 2.6 builtins. The expected usage of the future_builtins
3246 module is:
3247 from future_builtins import hex, oct
3248
Eric Smith7ef40bf2008-02-20 23:34:22 +00003249- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3250 exponents for exponents with absolute value < 100. Follows C99
3251 standard. This is a change on Windows, which would use 3 digits.
3252 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3253 so that any alterations it does to the resulting string will be
3254 available in stringlib/formatter.h (for float.__format__).
3255
Eric Smith5a3c1352008-02-19 13:21:56 +00003256- Implemented PEP 3101, Advanced String Formatting. This adds a new
3257 builtin format(); a format() method for str and unicode; a
3258 __format__() method to object, str, unicode, int, long, float, and
3259 datetime; the class string.Formatter; and the C API
3260 PyObject_Format().
3261
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262- Fixed several potential crashes, all caused by specially crafted
3263 __del__ methods exploiting objects in temporarily inconsistent
3264 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003265
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003266- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003267 prevent a possible crash: an Abstract Base Class would try to access
3268 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003269

Georg Brandl3ee81df2008-05-17 18:14:43 +00003273- Clear all free lists during a gc.collect() of the highest generation
3274 in order to allow pymalloc to free more arenas. Python may give back
3275 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003276
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277- Issue #2045: Fix an infinite recursion triggered when printing a
3278 subclass of collections.defaultdict, if its default_factory is set
3279 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003280
Christian Heimesf75dbef2008-02-08 00:11:31 +00003281- Fixed a minor memory leak in dictobject.c. The content of the free
3282 list was not freed on interpreter shutdown.
3283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Limit free list of method and builtin function objects to 256
3285 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003286
Georg Brandl3ee81df2008-05-17 18:14:43 +00003287- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3288 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003289 to compact the internal free lists of pre-allocted ints and floats.
3290
Georg Brandl3ee81df2008-05-17 18:14:43 +00003291- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3292 calls. Python expected the return type int but the fork familie
3293 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003294
Georg Brandl3ee81df2008-05-17 18:14:43 +00003295- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3302 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003303
Georg Brandl3ee81df2008-05-17 18:14:43 +00003304- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3305 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003306
Georg Brandl3ee81df2008-05-17 18:14:43 +00003307- Patch #1473257: generator objects gain a gi_code attribute. This is
3308 the same object as the func_code attribute of the function that
3309 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003310
Georg Brandl3ee81df2008-05-17 18:14:43 +00003311- Issue #1920: "while 0" statements were completely removed by the
3312 compiler, even in the presence of an "else" clause, which is
3313 supposed to be run when the condition is false. Now the compiler
3314 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003315
Guido van Rossumeead05f2008-01-24 18:21:02 +00003316- A few crashers fixed: weakref_in_del.py (issue #1377858);
3317 loosing_dict_ref.py (issue #1303614, test67.py);
3318 borrowed_ref_[34].py (not in tracker).
3319
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003320- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003321 suppressed while an extension is loaded by calling SetErrorMode in
3322 dynload_win.c. The error is still reported properly.
3323
Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003325 several extension methods and modules do not work without unicode
3326 support.
3327
Georg Brandl26543b12008-01-21 18:36:51 +00003328- Issue #1882: when compiling code from a string, encoding cookies in the
3329 second line of code were not always recognized correctly.
3330
Georg Brandl14404b62008-01-19 19:27:05 +00003331- Issue #1679: "0x" was taken as a valid integer literal.
3332
Georg Brandl6caad7d2008-01-26 14:19:22 +00003333- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003334 added.
3335
Christian Heimesc94e2b52008-01-14 04:13:37 +00003336- sys.float_info / PyFloat_GetInfo: The floating point information
3337 object was converted from a dict to a specialized structseq object.
3338
Georg Brandl3ee81df2008-05-17 18:14:43 +00003339- Patch #1816: Added sys.flags structseq. It exposes the status of
3340 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003341
Georg Brandl3ee81df2008-05-17 18:14:43 +00003342- Objects/structseq.c: Implemented new structseq representation. The
3343 patch makes structseqs (e.g. the return value of os.stat) more
3344 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003345
Georg Brandl3ee81df2008-05-17 18:14:43 +00003346- Patch #1700288: added a type attribute cache that caches method
3347 accesses, resulting in speedups in heavily object-oriented code.

3355 envvar and sys.dont_write_bytecode attribute. All these can be set
3356 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003357
Georg Brandl3ee81df2008-05-17 18:14:43 +00003358- Improve some exception messages when Windows fails to load an

3373 dictionary size. There is a new opcode, STORE_MAP, for adding
3374 entries to the dictionary.

3417
Georg Brandl3ee81df2008-05-17 18:14:43 +00003418- The enumerate() builtin function is no longer bounded to sequences
3419 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3420 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003421
Georg Brandl3ee81df2008-05-17 18:14:43 +00003422- Issue #1686386: Tuple's tp_repr did not take into account the
3423 possibility of having a self-referential tuple, which is possible
3424 from C code. Nor did object's tp_str consider that a type's tp_str
3425 could do something that could lead to an inifinite recursion.
3426 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3427 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Issue #1164: It was possible to trigger deadlock when using the
3430 'print' statement to write to a file since the GIL was not released
3431 as needed. Now PyObject_Print() does the right thing along with
3432 various tp_print implementations of the built-in types and those in
3433 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003443 PyObject_Call() never calling back out to Python code to trigger
3444 recursion depth updates/checks. Required the creation of a static

3471
Collin Winter62903052007-05-18 23:11:24 +00003472- except clauses may now be spelled either "except E, target:" or

3474 with Python 3.0.

3494
Guido van Rossum143b5642007-03-23 04:58:42 +00003495- Bug #1683368: The object.__init__() and object.__new__() methods are
3496 now stricter in rejecting excess arguments. The only time when
3497 either allows excess arguments is when it is not overridden and the
3498 other one is. For backwards compatibility, when both are
3499 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003500 warning later). Also, type.__init__() insists on the same signature
3501 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003503- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3504 object to complex using its __complex__() method before falling back
3505 to the __float__() method. Therefore, the functions in the cmath
3506 module now can operate on objects that define a __complex__()
3507 method.

3524
Georg Brandl7b9c5552007-03-12 14:30:05 +00003525- Bug #1678647: write a newline after printing an exception in any
3526 case, even when converting the value to a string failed.
3527
Georg Brandl871f1bc2007-03-12 13:17:36 +00003528- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003529 its argument, if it exists. If not, it will work like before. This
3530 allows customizing the output of dir() in the presence of a
3531 __getattr__().

3541 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00003543- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003544 makes the filenames the warning module prints much more sensible
3545 when a PYTHONSTARTUP file is used.

3560
Georg Brandl3ee81df2008-05-17 18:14:43 +00003561- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004114- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl92a6bae2007-03-13 17:43:32 +00004130- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004131 are set for invalid interpolation sequences that would lead to
4132 errors on reading back those values.

4188 TestCase and TestSuite subclasses (not instances) are no longer
4189 accepted in TestSuite.addTest(). This should cause no
4190 incompatibility since it never made sense with ordinary subclasses
4191 -- the failure just occurred later, with a more cumbersome
4192 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004479 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004580- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004581 time so that opening a database previously created with the DB_DUP
4582 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4583 opens. Specifically: dictionary assignment to a DB object will
4584 replace all values for a given key when the database allows
4585 duplicate values. DB users should use DB.put(k, v) when they want
4586 to store duplicates; not DB[k] = v.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004865- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004866 periodic threadstate and signal checking in tight loops. By
4867 default, this option is turned-off. It should only be enabled in
4868 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00004925
Georg Brandl3ee81df2008-05-17 18:14:43 +00004926- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4927 to ``PyTuple_SetItem``, it can be used to populate a brand new

4940
Georg Brandl3ee81df2008-05-17 18:14:43 +00004941- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4942 of w# format code incorrectly truncated the length to an int, even
4943 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4944 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004974- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4975 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
