73
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000074- Issue #7419: setlocale() could crash the interpreter on Windows when called
75 with invalid values.
76
Eric Smithc4ab8332009-11-29 17:40:57 +000077- Issue #3382: 'F' formatting for float and complex now convert the
78 result to upper case. This only affects 'inf' and 'nan', since 'f'
79 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000080
Mark Dickinson9dd5e162009-11-23 20:54:09 +000081- Remove switch from "%f" formatting to "%g" formatting for floats
82 larger than 1e50 in absolute value.
83
Mark Dickinson18cfada2009-11-23 18:46:41 +000084- Remove restrictions on precision when formatting floats. E.g.,
85 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
86 requested 120 significant digits instead.
87
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000088- Add Py3k warnings for parameter names in parenthesis.
89
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000090- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000091
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000092- Issue #7085: Fix crash when importing some extensions in a thread
93 on MacOSX 10.6.
94
Mark Dickinsonb678de82009-11-19 18:41:49 +000095- Issue #7117: repr(x) for a float x returns a result based on the
96 shortest decimal string that's guaranteed to round back to x under
97 correct rounding (with round-half-to-even rounding mode).
98 Previously it gave a string based on rounding x to 17 decimal digits.
99 repr(x) for a complex number behaves similarly. On platforms where
100 the correctly-rounded strtod and dtoa code is not supported (see below),
101 repr is unchanged.
102
103- Issue #7117: On almost all platforms: float-to-string and
104 string-to-float conversions within Python are now correctly rounded.
105 Places these conversions occur include: str for floats and complex
106 numbers; the float and complex constructors; old-style and new-style
107 numeric formatting; serialization and deserialization of floats and
108 complex numbers using marshal, pickle and json; parsing of float and
109 imaginary literals in Python code; Decimal-to-float conversion.
110
111 The conversions use a Python-adapted version of David Gay's
112 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
113 functions. This code is supported on Windows, and on Unix-like
114 platforms using gcc, icc or suncc as the C compiler. There may be a
115 small number of platforms on which correct operation of this code
116 cannot be guaranteed, so the code is not used: notably, this applies
117 to platforms where the C double format is not IEEE 754 binary64, and
118 to platforms on x86 hardware where the x87 FPU is set to 64-bit
119 precision and Python's configure script is unable to determine how
120 to change the FPU precision. On these platforms conversions use the
121 platform strtod and dtoa, as before.
122
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000123- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000124 now uses the correctly-rounded string <-> float conversions
125 described above (when available), and so produces correctly rounded
126 results that will display nicely under the float repr. There are
127 two related small changes: (1) round now accepts any class with an
128 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000129 floats for the second argument), and (2) an excessively large second
130 integer argument (e.g., round(1.234, 10**100)) no longer raises an
131 exception.
132
Philip Jenveyfab8be22009-11-17 02:42:26 +0000133- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
134
Benjamin Petersone36199b2009-11-12 23:39:44 +0000135- Fix several issues with compile(). The input can now contain Windows and Mac
136 newlines and is no longer required to end in a newline.
137
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000138- Remove length limitation when constructing a complex number from a
139 unicode string.
140
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000141- Issue #7244: itertools.izip_longest() no longer ignores exceptions
142 raised during the formation of an output tuple.
143
Mark Dickinson8d87dc02009-10-25 20:39:06 +0000144- Issue #1087418: Boost performance of bitwise operations for longs.
145
Antoine Pitrouefb60c02009-10-20 21:29:37 +0000146- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which

148 interpreter is killed. Patch by Adam Olsen.
149
Eric Smithc12781a2009-10-19 14:38:14 +0000150- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

155
Benjamin Peterson196b0922009-10-15 15:44:46 +0000156- Issue #7140: The __dict__ of a module should not be cleared unless the module
157 is the only object holding a reference to it.
158
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000159- Issue #1754094: Improve the stack depth calculation in the compiler.
160 There should be no other effect than a small decrease in memory use.
161 Patch by Christopher Tur Lesniewski-Laas.
162
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000163- Issue #7084: Fix a (very unlikely) crash when printing a list from one
164 thread, and mutating it from another one. Patch by Scott Dial.
165
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000166- Issue #1571184: The Unicode database contains properties for more characters.

179 of producing internally inconsistent Python longs.
180
Philip Jenveydbf3b252009-09-29 04:32:44 +0000181- Issue #6990: Fix threading.local subclasses leaving old state around

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000273- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
274 (1) inf and nan strings with trailing whitespace were incorrectly
275 rejected; (2) parsing of strings representing infinities and nans
276 was locale aware; and (3) the interpretation of fromhex('-nan')
277 didn't match that of float('-nan').
278
Eric Smitha985a3a2009-05-05 18:26:08 +0000279- Issue #5920: For float.__format__, change the behavior with the
280 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
281 to be like 'g' but with at least one decimal point and with a
282 default precision of 12. Previously, the behavior the same but with
283 a default precision of 6. This more closely matches str(), and
284 reduces surprises when adding alignment flags to the empty
285 presentation type. This also affects the new complex.__format__ in
286 the same way.
287
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000288- Issue #5890: in subclasses of 'property' the __doc__ attribute was

349
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000350- Issue #4688: Add a heuristic so that tuples and dicts containing only
351 untrackable objects are not tracked by the garbage collector. This can
352 reduce the size of collections and therefore the garbage collection overhead
353 on long-running programs, depending on their particular use of datatypes.

358
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000359- Issue #4258: Make it possible to use base 2**30 instead of base
360 2**15 for the internal representation of integers, for performance
361 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
362 --enable-big-digits option to configure, which overrides the
363 default. Add sys.long_info structseq to provide information about
364 the internal format.
365
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000366- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

381 float arguments.
382
Raymond Hettinger08259e82009-02-18 23:10:19 +0000383- Running Python with the -3 option now also warns about classic division
384 for ints and longs.
385
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000386- Issue #5260: Long integers now consume less memory: average
387 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
388 on a 64-bit system.
389
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000390- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

397
Georg Brandl29c6a282009-04-05 20:23:13 +0000398- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000399 were suppressing all exceptions. These include list(), filter(), map(),
400 zip(), and bytearray().
401
Benjamin Peterson596d3062009-01-19 15:42:23 +0000402- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Antoine Pitrouc2f02212009-01-13 23:13:52 +0000410- Issue #4935: The overflow checking code in the expandtabs() method common
411 to str, bytes and bytearray could be optimized away by the compiler, letting
412 the interpreter segfault instead of raising an error.
413
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000414- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000421- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
422 collecting the oldest generation) so that allocating lots of objects without
423 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000424 Martin von Löwis at

428
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000429- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
430 an existing .py counterpart, override the co_filename attributes of all
431 code objects if the original filename is obsolete (which can happen if the
432 file has been renamed, moved, or if it is accessed through different paths).
433 Patch by Ziga Seilnacht and Jean-Paul Calderone.

442
Nick Coghlan180e4002008-12-30 01:18:48 +0000443- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
444 where the tp_hash and tp_dict slots are both NULL.
445
Benjamin Peterson7af65562008-12-29 17:56:58 +0000446- Issue #4764: With io.open, IOError.filename is set when trying to open a

453 bytearray.translate(). It was always allowed for bytes.translate().
454
Skip Montanarof205c132008-12-23 03:30:15 +0000455- Added test case to ensure attempts to read from a file opened for writing
456 fail.
457
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000458- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

471 exceptions.
472
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000473- Issue #4445: Replace "sizeof(PyStringObject)" with
474 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
475 str instances. On a typical machine this saves 3 bytes of memory
476 (on average) per string allocation.
477
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000478- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
479 interpreter to abort ("Fatal Python error: Could not reset the stack!")
480 instead of throwing a MemoryError.
481
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000482- Issue #3689: The list reversed iterator now supports __length_hint__

484
Benjamin Petersonc078f922008-11-21 22:27:24 +0000485- Issue #4367: Python would segfault during compiling when the unicodedata

487
Vinay Sajip213faca2008-12-03 23:22:58 +0000488- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000489 method on file objects with closefd=False. The file descriptor is still
490 kept open but the file object behaves like a closed file. The ``FileIO``
491 object also got a new readonly attribute ``closefd``.
492
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000493- Issue #4348: Some bytearray methods returned that didn't cause any change to

504
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000505- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
506 method does not return iterators for the 4th and 5th items.
507
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000508- Issue #4209: Enabling unicode_literals and the print_function in the same
509 __future__ import didn't work.
510
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000511- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000512 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000514- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
515 returned a path longer than MAX_PATH. (But It's doubtful this code path is
516 really executed because I cannot move to such directory on win2k)
517
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000518- Issue #4069: When set.remove(element) is used with a set element, the element
519 is temporarily replaced with an equivalent frozenset. But the eventual
520 KeyError would always report the empty frozenset([]) as the missing key. Now
521 it correctly refers to the initial element.

539 returned them on 64bit platforms.
540
Walter Dörwalded960ac2009-05-03 22:36:33 +0000541- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
542 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
543 step. This avoids problems with counting UTF-8 bytes that ignores the effect
544 of using the replace error handler in PyUnicode_DecodeUTF8().
545
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000546- Issue #3739: The unicode-internal encoder now reports the number of characters
547 consumed like any other encoder (instead of the number of bytes).
548
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000549- Issue #2422: When compiled with the ``--with-valgrind`` option, the
550 pymalloc allocator will be automatically disabled when running under
551 Valgrind. This gives improved memory leak detection when running
552 under Valgrind, while taking advantage of pymalloc at other times.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001932- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

1934 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1935 ``printf`` function, whereas PyString_FromFormat has an independent

1961 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1962 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002101What's New in Python 2.6 beta 3?
2102================================
2103
Barry Warsaw07a4a382008-08-21 01:15:08 +00002104*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002105
2106Core and Builtins
2107-----------------
2108
Guido van Rossumf8402962008-08-20 15:01:50 +00002109- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2110 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2111 extensions do not automatically benefit from the class attribute
2112 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2113 to their tp_flags field if they care. This is a backwards
2114 compatibility feature; in 3.0, all types will use the cache by
2115 default.
2116
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002117- Keyword arguments can now follow starred arguments. (``f(a, *args,
2118 keyword=23)`` is now valid syntax.)
2119
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002120- ctypes function pointers that are COM methods have a boolean True
2121 value again.
2122
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002123- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2124 by denying s# to parse objects that have a releasebuffer procedure,
2125 and introducing s*.
2126
Georg Brandl1e13ea92008-08-11 09:07:59 +00002127- Issue #3537: Fix an assertion failure when an empty but presized dict
2128 object was stored in the freelist.
2129
Mark Dickinsonb6467572008-08-04 21:30:09 +00002130- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2131 ValueError consistently across platforms.
2132
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002133- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2134 (64bit Unix, for example), unichr() would truncate its argument and return
2135 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2136
Neal Norwitze7d8be82008-07-31 17:17:14 +00002137- Apply security patches from Apple.
2138
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002139- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2140 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2141
Antoine Pitrou92f82162008-07-25 22:22:08 +00002142- Issue #1819: function calls with several named parameters are now on
2143 average 35% faster (as measured by pybench).
2144
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002145- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2146 the python debugger steps into a class statement: the free variables (local
2147 variables defined in an outer scope) would be deleted from the outer scope.
2148
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002149- Issue #2620: Overflow checking when allocating or reallocating memory
2150 was not always being done properly in some python types and extension
2151 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2152 all been updated to perform better checks and places in the code that
2153 would previously leak memory on the error path when such an allocation
2154 failed have been fixed.
2155

2157-------
2158
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002159- Issue #3612: Added some missing basic types in ctypes.wintypes.
2160
Benjamin Petersone977ad42008-08-20 01:42:01 +00002161- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2162 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2163
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002164- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2165 version reported by these tools does not necessarily follow the python
2166 version numbering scheme, so the module is less strict when parsing it.
2167
Nick Coghlanf70385a2008-08-18 12:42:46 +00002168- Issue #2235: Added Py3k warnings for types which will become unhashable
2169 under the stricter __hash__ inheritance rules in 3.0. Several types
2170 which did not meet the rules for hash invariants and were already
2171 unhashable in 3.0 have now been explicitly flagged as unhashable in
2172 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2173 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2174
Brett Cannon88f801d2008-08-18 00:46:22 +00002175- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2183
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002184- Issue #3575: Incremental decoder's decode function now takes bytearray
2185 by using 's*' instead of 't#'.
2186
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002187- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002188 fails unicode conversion on 2nd parameter. (windows only)
2189
Facundo Batista94f243a2008-08-17 03:38:39 +00002190- Issue 2464. urllib2 now supports a malformation in the URL received
2191 in a redirect.
2192
Brett Cannonabe423e2008-08-16 21:47:07 +00002193- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002194 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002195
Facundo Batistaeb90b782008-08-16 14:44:07 +00002196- Issue #2776: fixed small issue when handling an URL with double slash
2197 after a 302 response in the case of not going through a proxy.
2198
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002199- Issue #2676: in the email package, content-type parsing was hanging on
2200 pathological input because of quadratic or exponential behaviour of a
2201 regular expression.
2202
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002203- Issue #3476: binary buffered reading through the new "io" library is now
2204 thread-safe.
2205
Brett Cannonbf3157b2008-08-14 05:00:03 +00002206- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2207 since mimetools itself is deprecated. Because modules are cached, all
2208 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2209
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002210- Issue #3134: shutil referenced undefined WindowsError symbol.
2211
Robert Schuppenies14646332008-08-10 11:01:53 +00002212- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2213 menu entries were not deleted.
2214
Brett Cannon83e81842008-08-09 23:30:55 +00002215- Copied the implementation of reduce() to _functools.reduce() to have a
2216 version that did not raise a DeprecationWarning under -3.
2217
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002218- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2219 a MemoryError rather than silently stop the iteration.
2220
Guido van Rossum59ce9012008-08-09 14:55:34 +00002221- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2222 to _sre.compile() will now be rejected. This should not affect anybody
2223 since the re.compile() function never generates invalid re-bytecode.
2224
Skip Montanaroa032bf42008-08-08 22:52:51 +00002225- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2226 upon first access it can be automatically initialized from the csv file if
2227 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00002229- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2230 the reload() built-in has been removed.
2231
Brett Cannon7e30b672008-08-04 21:52:25 +00002232- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002233 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002244 asking for a specific length. This problem only affected files opened
2245 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002246

2271 file name rather than a ZipInfo instance, so files are extracted with
2272 mode 0600 rather than 000 under Unix.
2273
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002274- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2275 argument in python 2.5, this broke code that subclassed Popen to include its

2287 interaction with the tp_hash slot (added in 2.6b2) are now documented
2288
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002289- Issue #643841: The language reference now provides more detailed
2290 coverage of the lookup process for special methods. The disclaimers
2291 regarding lack of coverage of new-style classes have also been
2292 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002295What's New in Python 2.6 beta 2?
2296================================
2297
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002298*Release date: 17-Jul-2008*
2299
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002300Core and Builtins
2301-----------------
2302
Georg Brandl3e483f62008-07-16 22:57:41 +00002303- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2304 its methods now allow for items objects that can be converted to
2305 an integer using operator.index().
2306
Mark Dickinson64b7e502008-07-16 09:40:03 +00002307- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2308 produced a ValueError instead of giving the correct float.
2309
Eric Smitha5fa5a22008-07-16 00:11:49 +00002310- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2311 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2312
Mark Dickinson7103aa42008-07-15 19:08:33 +00002313- Issue #3008: the float type has a new instance method 'float.hex'
2314 and a new class method 'float.fromhex' to convert floating-point
2315 numbers to and from hexadecimal strings, respectively.
2316
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002317- Issue #2235: __hash__ is once again inherited by default. To allow
2318 collections.Hashable to remain meaningful in the presence of the
2319 default hash implementation (object.__hash__), it is now possible
2320 to explicit block inheritance of hash by setting __hash__=None at
2321 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2322 level.
2323
Nick Coghlanb028f502008-07-13 14:52:36 +00002324- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2325 the parent module cannot be found while performing an absolute import.
2326 This means that an incorrectly defined __package__ attribute will
2327 now only prevent relative imports in that module rather than causing
2328 all imports from that module to fail.
2329
Nick Coghlan14ff9942008-07-08 14:21:42 +00002330- Issue #2517: Allow unicode messages in Exceptions again by correctly
2331 bypassing the instance dictionary when looking up __unicode__ on
2332 new-style classes.
2333
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002334- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2335 set to a custom object whose write() method happens to install
2336 another file in sys.stdout.
2337
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002338- Issue #3088: Corrected a race condition in classes derived from
2339 threading.local: the first member set by a thread could be saved in
2340 another thread's dictionary.
2341
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002342- Issue #3004: Minor change to slice.indices(): the start and stop
2343 arguments are now treated identically, making the behaviour easier
2344 to describe and understand. For example, slice(None, -10,
2345 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2346 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2347 10, -1).
2348
Georg Brandl278fc502008-07-19 12:46:12 +00002349- Issue #3219: Calling a function with repeated keyword arguments,
2350 f(a=2, a=23), would not cause a syntax error. This was a regression
2351 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002352
Georg Brandl278fc502008-07-19 12:46:12 +00002353- Issue #2862: Make int and float freelist management consistent with
2354 other freelists. Changes their CompactFreeList apis into
2355 ClearFreeList apis and calls them via gc.collect().

2358-------
2359
Thomas Heller57adf222008-08-14 19:10:48 +00002360- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2361 api functions without holding the GIL, which could lead to a fatal
2362 error when they failed.
2363
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002364- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2373 ForkingPickler.register() to resolve conflict with ctypes.
2374
Vinay Sajip51e65192008-07-18 09:01:10 +00002375- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002376
Thomas Heller880f5292008-07-15 19:39:38 +00002377- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2378 a valid dlerror() message.
2379
Thomas Heller2bad6572008-07-15 17:19:50 +00002380- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2381 incomplete structure was created.
2382

2386
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002387- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002388
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002389- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2390 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002391 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002392 content-length. The problem had been corrected in the 2.4 branch, but never
2393 merged into trunk.
2394
Georg Brandle78fbcc2008-07-05 10:13:36 +00002395- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002406 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002407
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002408- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2409 handling is now the same as that of other special attributes like __name__).
2410
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002411- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2412 removal in Python 3.0 in favor of urllib2.urlopen().

2865 using the 'warning's machinery in such places as the parser where
2866 use of pure Python code is not possible. Both the ``showarning()``
2867 and ``formatwarning()`` gain an optional 'line' argument which is
2868 not called by default for backwards-compatibility reasons. Setting
2869 ``warnings.showwarning()`` to an implementation that lacks support
2870 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002933- Issue #2550: The approach used by client/server code for obtaining
2934 ports to listen on in network-oriented tests has been refined in an
2935 effort to facilitate running multiple instances of the entire
2936 regression test suite in parallel without issue.
2937 test_support.bind_port() has been fixed such that it will always
2938 return a unique port -- which wasn't always the case with the
2939 previous implementation, especially if socket options had been set
2940 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2941 new implementation of bind_port() will actually raise an exception
2942 if it is passed an AF_INET/SOCK_STREAM socket with either the
2943 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2944 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2945 the socket it's been passed. This currently only applies to
2946 Windows. This option prevents any other sockets from binding to the
2947 host/port we've bound to, thus removing the possibility of the
2948 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2949 when a second SOCK_STREAM socket binds and accepts to a host/port
2950 that's already been bound by another socket. The optional preferred
2951 port parameter to bind_port() has been removed. Under no
2952 circumstances should tests be hard coding ports!
2953
2954 test_support.find_unused_port() has also been introduced, which will
2955 pass a temporary socket object to bind_port() in order to obtain an
2956 unused port. The temporary socket object is then closed and
2957 deleted, and the port is returned. This method should only be used
2958 for obtaining an unused port in order to pass to an external program
2959 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2960 a parameter to a server-oriented class that doesn't give you direct
2961 access to the underlying socket used.
2962
2963 Finally, test_support.HOST has been introduced, which should be used
2964 for the host argument of any relevant socket calls (i.e. bind and
2965 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002966
2967 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002968 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002969 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2970 test_asynchat and test_socket_ssl.
2971
Georg Brandl3ee81df2008-05-17 18:14:43 +00002972 It is now possible for multiple instances of the regression test
2973 suite to run in parallel without issue.

3240-----------------
3241
Fred Drakea8ee94b2008-03-01 02:45:07 +00003242- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003243 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003245- Issue #2067: file.__exit__() now calls subclasses' close() method.
3246
3247- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003248
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003249- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003250 issue 215555 for a discussion.
3251
Eric Smitha73fbe72008-02-23 03:09:44 +00003252- Added the future_builtins module, which contains hex() and oct().
3253 These are the PEP 3127 version of these functions, designed to be
3254 compatible with the hex() and oct() builtins from Python 3.0. They
3255 differ slightly in their output formats from the existing, unchanged
3256 Python 2.6 builtins. The expected usage of the future_builtins
3257 module is:
3258 from future_builtins import hex, oct
3259
Eric Smith7ef40bf2008-02-20 23:34:22 +00003260- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3261 exponents for exponents with absolute value < 100. Follows C99
3262 standard. This is a change on Windows, which would use 3 digits.
3263 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3264 so that any alterations it does to the resulting string will be
3265 available in stringlib/formatter.h (for float.__format__).
3266
Eric Smith5a3c1352008-02-19 13:21:56 +00003267- Implemented PEP 3101, Advanced String Formatting. This adds a new
3268 builtin format(); a format() method for str and unicode; a
3269 __format__() method to object, str, unicode, int, long, float, and
3270 datetime; the class string.Formatter; and the C API
3271 PyObject_Format().
3272
Georg Brandl3ee81df2008-05-17 18:14:43 +00003273- Fixed several potential crashes, all caused by specially crafted
3274 __del__ methods exploiting objects in temporarily inconsistent
3275 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003276
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003277- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003278 prevent a possible crash: an Abstract Base Class would try to access
3279 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003280

Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Clear all free lists during a gc.collect() of the highest generation
3285 in order to allow pymalloc to free more arenas. Python may give back
3286 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003287
Georg Brandl3ee81df2008-05-17 18:14:43 +00003288- Issue #2045: Fix an infinite recursion triggered when printing a
3289 subclass of collections.defaultdict, if its default_factory is set
3290 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003291
Christian Heimesf75dbef2008-02-08 00:11:31 +00003292- Fixed a minor memory leak in dictobject.c. The content of the free
3293 list was not freed on interpreter shutdown.
3294
Georg Brandl3ee81df2008-05-17 18:14:43 +00003295- Limit free list of method and builtin function objects to 256
3296 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003297
Georg Brandl3ee81df2008-05-17 18:14:43 +00003298- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3299 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003300 to compact the internal free lists of pre-allocted ints and floats.
3301
Georg Brandl3ee81df2008-05-17 18:14:43 +00003302- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3303 calls. Python expected the return type int but the fork familie
3304 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003305
Georg Brandl3ee81df2008-05-17 18:14:43 +00003306- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3316 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003317
Georg Brandl3ee81df2008-05-17 18:14:43 +00003318- Patch #1473257: generator objects gain a gi_code attribute. This is
3319 the same object as the func_code attribute of the function that
3320 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003321
Georg Brandl3ee81df2008-05-17 18:14:43 +00003322- Issue #1920: "while 0" statements were completely removed by the
3323 compiler, even in the presence of an "else" clause, which is
3324 supposed to be run when the condition is false. Now the compiler
3325 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003326
Guido van Rossumeead05f2008-01-24 18:21:02 +00003327- A few crashers fixed: weakref_in_del.py (issue #1377858);
3328 loosing_dict_ref.py (issue #1303614, test67.py);
3329 borrowed_ref_[34].py (not in tracker).
3330
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003331- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003332 suppressed while an extension is loaded by calling SetErrorMode in

3334
Georg Brandl3ee81df2008-05-17 18:14:43 +00003335- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003336 several extension methods and modules do not work without unicode
3337 support.
3338
Georg Brandl26543b12008-01-21 18:36:51 +00003339- Issue #1882: when compiling code from a string, encoding cookies in the
3340 second line of code were not always recognized correctly.
3341
Georg Brandl14404b62008-01-19 19:27:05 +00003342- Issue #1679: "0x" was taken as a valid integer literal.
3343
Georg Brandl6caad7d2008-01-26 14:19:22 +00003344- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003345 added.
3346
Christian Heimesc94e2b52008-01-14 04:13:37 +00003347- sys.float_info / PyFloat_GetInfo: The floating point information
3348 object was converted from a dict to a specialized structseq object.
3349
Georg Brandl3ee81df2008-05-17 18:14:43 +00003350- Patch #1816: Added sys.flags structseq. It exposes the status of
3351 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003352
Georg Brandl3ee81df2008-05-17 18:14:43 +00003353- Objects/structseq.c: Implemented new structseq representation. The
3354 patch makes structseqs (e.g. the return value of os.stat) more
3355 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003356
Georg Brandl3ee81df2008-05-17 18:14:43 +00003357- Patch #1700288: added a type attribute cache that caches method
3358 accesses, resulting in speedups in heavily object-oriented code.

3364
Georg Brandl3ee81df2008-05-17 18:14:43 +00003365- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3366 envvar and sys.dont_write_bytecode attribute. All these can be set
3367 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003369- Improve some exception messages when Windows fails to load an
3370 extension module. Now we get for example '%1 is not a valid Win32
3371 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003382- Compiler now generates simpler and faster code for dictionary
3383 literals. The oparg for BUILD_MAP now indicates an estimated
3384 dictionary size. There is a new opcode, STORE_MAP, for adding
3385 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Patch #1739468: Directories and zipfiles containing a __main__.py
3415 file can now be directly executed by passing their name to the
3416 interpreter. The directory/zipfile is automatically inserted as the
3417 first entry in sys.path.

3420 function uses a generator expression when at the same time the
3421 executed code is closing a paused generator.

3428
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- The enumerate() builtin function is no longer bounded to sequences
3430 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3431 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003432
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433- Issue #1686386: Tuple's tp_repr did not take into account the
3434 possibility of having a self-referential tuple, which is possible
3435 from C code. Nor did object's tp_str consider that a type's tp_str
3436 could do something that could lead to an inifinite recursion.
3437 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3438 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003439
Georg Brandl3ee81df2008-05-17 18:14:43 +00003440- Issue #1164: It was possible to trigger deadlock when using the
3441 'print' statement to write to a file since the GIL was not released
3442 as needed. Now PyObject_Print() does the right thing along with
3443 various tp_print implementations of the built-in types and those in
3444 the collections module.

Brett Cannona0c05512007-09-10 21:38:27 +00003452
Brett Cannon1e534b52007-09-07 04:18:30 +00003453- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003454 PyObject_Call() never calling back out to Python code to trigger
3455 recursion depth updates/checks. Required the creation of a static
3456 RuntimeError instance in case normalizing an exception put the
3457 recursion check value past its limit. Fixes crashers
3458 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003473- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003474 __*__ attributes. (Some already existed, e.g., __doc__ and
3475 __name__.)

3479
Georg Brandl2134e752007-05-21 20:34:16 +00003480- Patch #1686487: you can now pass any mapping after '**' in function
3481 calls.
3482
Collin Winter62903052007-05-18 23:11:24 +00003483- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003484 "except E as target:". This is to provide forwards compatibility
3485 with Python 3.0.

3491
Vinay Sajip8549ce32007-05-06 17:53:37 +00003492- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003493 setting a plain string, ie don't expand to single letter identifiers.
3494
Raymond Hettinger13936692007-04-11 18:40:58 +00003495- Request #1191699: Slices can now be pickled.
3496
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003497- Request #1193128: str.translate() now allows a None argument for

3499 remaining characters.
3500
Georg Brandl5cb76c12007-03-21 09:00:39 +00003501- Patch #1682205: a TypeError while unpacking an iterable is no longer

3505
Guido van Rossum143b5642007-03-23 04:58:42 +00003506- Bug #1683368: The object.__init__() and object.__new__() methods are
3507 now stricter in rejecting excess arguments. The only time when
3508 either allows excess arguments is when it is not overridden and the
3509 other one is. For backwards compatibility, when both are
3510 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003511 warning later). Also, type.__init__() insists on the same signature
3512 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003513
Georg Brandl3ee81df2008-05-17 18:14:43 +00003514- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3515 object to complex using its __complex__() method before falling back
3516 to the __float__() method. Therefore, the functions in the cmath
3517 module now can operate on objects that define a __complex__()
3518 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003519
Georg Brandl3ee81df2008-05-17 18:14:43 +00003520- Patch #1623563: allow __class__ assignment for classes with
3521 __slots__. The old and the new class are still required to have the
3522 same slot names.

3535
Georg Brandl7b9c5552007-03-12 14:30:05 +00003536- Bug #1678647: write a newline after printing an exception in any
3537 case, even when converting the value to a string failed.
3538
Georg Brandl871f1bc2007-03-12 13:17:36 +00003539- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540 its argument, if it exists. If not, it will work like before. This
3541 allows customizing the output of dir() in the presence of a
3542 __getattr__().

3552 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003553
Georg Brandlaa2321b2007-03-07 00:40:28 +00003554- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003555 makes the filenames the warning module prints much more sensible
3556 when a PYTHONSTARTUP file is used.

3571
Georg Brandl3ee81df2008-05-17 18:14:43 +00003572- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004107 AttributeError instead of an IOError when the server's response
4108 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004109

Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Patch #1530482: add pydoc.render_doc() which returns the

4140
Georg Brandl92a6bae2007-03-13 17:43:32 +00004141- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142 are set for invalid interpolation sequences that would lead to
4143 errors on reading back those values.

4197
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198- unittest now verifies more of its assumptions. In particular,
4199 TestCase and TestSuite subclasses (not instances) are no longer
4200 accepted in TestSuite.addTest(). This should cause no
4201 incompatibility since it never made sense with ordinary subclasses
4202 -- the failure just occurred later, with a more cumbersome
4203 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004592 time so that opening a database previously created with the DB_DUP
4593 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4594 opens. Specifically: dictionary assignment to a DB object will
4595 replace all values for a given key when the database allows
4596 duplicate values. DB users should use DB.put(k, v) when they want
4597 to store duplicates; not DB[k] = v.

4606 behavior of quoting dots if they are the second character of any
4607 line.

4953 of w# format code incorrectly truncated the length to an int, even
4954 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4955 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004985- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4986 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
