44Core and Builtins
45-----------------
46
Benjamin Petersonecdae192010-01-04 00:43:01 +000047- The __complex__ method is now looked up on the class of instances to make it
48 consistent with other special methods.
49
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000050- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
51 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
52
Mark Dickinson1b34d252010-01-01 17:27:30 +000053- Issue #5080: A number of functions and methods previously produced a
54 DeprecationWarning when passed a float argument where an integer was
55 expected. These functions and methods now raise TypeError instead.
56 The majority of the effects of this change are in the extension
57 modules, but some core functions and methods are affected: notably
58 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
59 methods.
60
Benjamin Peterson0f02d392009-12-30 19:34:10 +000061- Issue #7604: Deleting an unset slotted attribute did not raise an
62 AttributeError.
63
Mark Dickinson99d652e2009-12-30 12:12:23 +000064- Issue #7534: Fix handling of IEEE specials (infinities, nans,
65 negative zero) in ** operator. The behaviour now conforms to that
66 described in C99 Annex F.
67
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000068- Issue #7579: the msvcrt module now has docstrings for all its functions.
69
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000070- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
71 used to drop the time part of the result.
72
Mark Dickinson46572832009-12-27 14:55:57 +000073- Issue #1811: improve accuracy and cross-platform consistency for
74 true division of integers: the result of a/b is now correctly
75 rounded for ints a and b (at least on IEEE 754 platforms), and in
76 particular does not depend on the internal representation of a long.
77
Ezio Melottif84caf42009-12-24 22:25:17 +000078- Issue #6108: unicode(exception) and str(exception) should return the same
79 message when only __str__ (and not __unicode__) is overridden in the subclass.
80
Ronald Oussoren92919a62009-12-24 13:30:58 +000081- Issue #6834: replace the implementation for the 'python' and 'pythonw'
82 executables on OSX.
83
84 These executables now work properly with the arch(1) command:
85 ``arch -ppc python`` will start a universal binary version of python
86 in PPC mode (unlike previous releases).
87
R. David Murray0a0a1a82009-12-14 16:28:26 +000088- Issue #1680159: unicode coercion during an 'in' operation no longer masks
89 the underlying error when the coercion fails for the left hand operand.
90
Benjamin Peterson4895af42009-12-13 16:36:53 +000091- Issue #7491: Metaclass's __cmp__ method was ignored.

102 by Arfrever.
103
Antoine Pitrou80157252010-01-08 19:20:17 +0000104- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
105 renaming of `cPickle` to `pickle`. The warning was annoying since there's
106 no alternative to cPickle if you care about performance. Patch by Florent
107 Xicluna.
108
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000109- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

116 and make it implement the `io.BufferedIOBase` ABC to allow for further
117 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
118
119- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000120 parameter to allow specifying where your connections come from.

Senthil Kumaran7713acf2009-12-20 06:05:13 +0000138 Patch by Tatsuhiro Tsujikawa.
139
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000140- Issue #7349: Make methods of file objects in the io module accept None as an
141 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
142 the same as passing no argument.
143
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000144- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
145 like other file objects.
146
Lars Gustäbel92ca7562009-12-13 11:32:27 +0000147- Issue #7357: tarfile no longer suppresses fatal extraction errors by
148 default.
149

R. David Murray93321f32009-12-09 15:15:31 +0000152- Issue #5949: fixed IMAP4_SSL hang when the IMAP server response is
153 missing proper end-of-line termination.
154
Tarek Ziadé2421d562009-12-20 23:23:34 +0000155- Issue #7457: added a read_pkg_file method to

213-----------------
214
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000215- Issue #7419: setlocale() could crash the interpreter on Windows when called
216 with invalid values.
217
Eric Smithc4ab8332009-11-29 17:40:57 +0000218- Issue #3382: 'F' formatting for float and complex now convert the
219 result to upper case. This only affects 'inf' and 'nan', since 'f'
220 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000221
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000222- Remove switch from "%f" formatting to "%g" formatting for floats
223 larger than 1e50 in absolute value.
224
Mark Dickinson18cfada2009-11-23 18:46:41 +0000225- Remove restrictions on precision when formatting floats. E.g.,
226 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
227 requested 120 significant digits instead.
228
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000229- Add Py3k warnings for parameter names in parenthesis.
230
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000231- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000232
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000233- Issue #7085: Fix crash when importing some extensions in a thread
234 on MacOSX 10.6.
235
Mark Dickinsonb678de82009-11-19 18:41:49 +0000236- Issue #7117: repr(x) for a float x returns a result based on the
237 shortest decimal string that's guaranteed to round back to x under
238 correct rounding (with round-half-to-even rounding mode).
239 Previously it gave a string based on rounding x to 17 decimal digits.
240 repr(x) for a complex number behaves similarly. On platforms where
241 the correctly-rounded strtod and dtoa code is not supported (see below),
242 repr is unchanged.
243
244- Issue #7117: On almost all platforms: float-to-string and
245 string-to-float conversions within Python are now correctly rounded.
246 Places these conversions occur include: str for floats and complex
247 numbers; the float and complex constructors; old-style and new-style
248 numeric formatting; serialization and deserialization of floats and
249 complex numbers using marshal, pickle and json; parsing of float and
250 imaginary literals in Python code; Decimal-to-float conversion.
251
252 The conversions use a Python-adapted version of David Gay's
253 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
254 functions. This code is supported on Windows, and on Unix-like
255 platforms using gcc, icc or suncc as the C compiler. There may be a
256 small number of platforms on which correct operation of this code
257 cannot be guaranteed, so the code is not used: notably, this applies
258 to platforms where the C double format is not IEEE 754 binary64, and
259 to platforms on x86 hardware where the x87 FPU is set to 64-bit
260 precision and Python's configure script is unable to determine how
261 to change the FPU precision. On these platforms conversions use the
262 platform strtod and dtoa, as before.
263
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000264- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000265 now uses the correctly-rounded string <-> float conversions
266 described above (when available), and so produces correctly rounded
267 results that will display nicely under the float repr. There are
268 two related small changes: (1) round now accepts any class with an
269 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000270 floats for the second argument), and (2) an excessively large second
271 integer argument (e.g., round(1.234, 10**100)) no longer raises an
272 exception.
273
Philip Jenveyfab8be22009-11-17 02:42:26 +0000274- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
275
Benjamin Petersone36199b2009-11-12 23:39:44 +0000276- Fix several issues with compile(). The input can now contain Windows and Mac
277 newlines and is no longer required to end in a newline.
278
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000279- Remove length limitation when constructing a complex number from a
280 unicode string.
281
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000282- Issue #7244: itertools.izip_longest() no longer ignores exceptions
283 raised during the formation of an output tuple.
284
Mark Dickinson8d87dc02009-10-25 20:39:06 +0000285- Issue #1087418: Boost performance of bitwise operations for longs.
286
Antoine Pitrouefb60c02009-10-20 21:29:37 +0000287- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which

289 interpreter is killed. Patch by Adam Olsen.
290
Eric Smithc12781a2009-10-19 14:38:14 +0000291- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

296
Benjamin Peterson196b0922009-10-15 15:44:46 +0000297- Issue #7140: The __dict__ of a module should not be cleared unless the module
298 is the only object holding a reference to it.
299
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000300- Issue #1754094: Improve the stack depth calculation in the compiler.
301 There should be no other effect than a small decrease in memory use.
302 Patch by Christopher Tur Lesniewski-Laas.
303
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000304- Issue #7084: Fix a (very unlikely) crash when printing a list from one
305 thread, and mutating it from another one. Patch by Scott Dial.
306

417 was locale aware; and (3) the interpretation of fromhex('-nan')
418 didn't match that of float('-nan').
419
Eric Smitha985a3a2009-05-05 18:26:08 +0000420- Issue #5920: For float.__format__, change the behavior with the
421 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
422 to be like 'g' but with at least one decimal point and with a
423 default precision of 12. Previously, the behavior the same but with
424 a default precision of 6. This more closely matches str(), and
425 reduces surprises when adding alignment flags to the empty
426 presentation type. This also affects the new complex.__format__ in
427 the same way.
428
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000429- Issue #5890: in subclasses of 'property' the __doc__ attribute was

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

529 on a 64-bit system.
530
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000531- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

538
Georg Brandl29c6a282009-04-05 20:23:13 +0000539- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000540 were suppressing all exceptions. These include list(), filter(), map(),

612 exceptions.
613
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000614- Issue #4445: Replace "sizeof(PyStringObject)" with
615 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
616 str instances. On a typical machine this saves 3 bytes of memory
617 (on average) per string allocation.
618
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000619- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
620 interpreter to abort ("Fatal Python error: Could not reset the stack!")
621 instead of throwing a MemoryError.
622
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000623- Issue #3689: The list reversed iterator now supports __length_hint__

625
Benjamin Petersonc078f922008-11-21 22:27:24 +0000626- Issue #4367: Python would segfault during compiling when the unicodedata

628
Vinay Sajip213faca2008-12-03 23:22:58 +0000629- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000630 method on file objects with closefd=False. The file descriptor is still
631 kept open but the file object behaves like a closed file. The ``FileIO``
632 object also got a new readonly attribute ``closefd``.
633
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000634- Issue #4348: Some bytearray methods returned that didn't cause any change to
635 the bytearray, returned the same bytearray instead of a copy.
636

647 method does not return iterators for the 4th and 5th items.
648
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000649- Issue #4209: Enabling unicode_literals and the print_function in the same
650 __future__ import didn't work.
651
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000652- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000653 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000654
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000655- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
656 returned a path longer than MAX_PATH. (But It's doubtful this code path is
657 really executed because I cannot move to such directory on win2k)
658
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000659- Issue #4069: When set.remove(element) is used with a set element, the element
660 is temporarily replaced with an equivalent frozenset. But the eventual
661 KeyError would always report the empty frozenset([]) as the missing key. Now
662 it correctly refers to the initial element.
663
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000664- Issue #4509: Various issues surrounding resize of bytearray objects to
665 which there are buffer exports.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000679- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
680 returned them on 64bit platforms.
681
Walter Dörwalded960ac2009-05-03 22:36:33 +0000682- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
683 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
684 step. This avoids problems with counting UTF-8 bytes that ignores the effect
685 of using the replace error handler in PyUnicode_DecodeUTF8().
686
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000687- Issue #3739: The unicode-internal encoder now reports the number of characters
688 consumed like any other encoder (instead of the number of bytes).
689
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000690- Issue #2422: When compiled with the ``--with-valgrind`` option, the
691 pymalloc allocator will be automatically disabled when running under
692 Valgrind. This gives improved memory leak detection when running
693 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +0000762- Issue #6816: runpy now provides a run_path function that allows Python code
763 to execute file paths that refer to source or compiled Python files as well
764 as zipfiles, directories and other valid sys.path entries that contain a

1930 leak-chasing test runs give sensible results. The previous method of
1931 reaping threads could return successfully while some Thread objects were

2074
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002075- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2076 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2077 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2078 ``printf`` function, whereas PyString_FromFormat has an independent
2079 implementation and uses "%zd" on all platforms for size_t values.
2080 This makes a difference on win64, where ``printf`` needs "%Id" to display
2081 64bit values.

2087 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002098 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002100- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002101 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2102 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2103 when given a tuple of classes as second argument, were looking up
2104 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2105 type object.

2250-----------------
2251
Guido van Rossumf8402962008-08-20 15:01:50 +00002252- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2253 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2254 extensions do not automatically benefit from the class attribute
2255 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2256 to their tp_flags field if they care. This is a backwards
2257 compatibility feature; in 3.0, all types will use the cache by
2258 default.
2259
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002260- Keyword arguments can now follow starred arguments. (``f(a, *args,

Georg Brandl1e13ea92008-08-11 09:07:59 +00002270- Issue #3537: Fix an assertion failure when an empty but presized dict
2271 object was stored in the freelist.
2272
Mark Dickinsonb6467572008-08-04 21:30:09 +00002273- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2274 ValueError consistently across platforms.
2275
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002276- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2277 (64bit Unix, for example), unichr() would truncate its argument and return
2278 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2279
Neal Norwitze7d8be82008-07-31 17:17:14 +00002280- Apply security patches from Apple.
2281
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002282- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2283 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2284
Antoine Pitrou92f82162008-07-25 22:22:08 +00002285- Issue #1819: function calls with several named parameters are now on
2286 average 35% faster (as measured by pybench).
2287
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002288- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2289 the python debugger steps into a class statement: the free variables (local
2290 variables defined in an outer scope) would be deleted from the outer scope.
2291
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002292- Issue #2620: Overflow checking when allocating or reallocating memory
2293 was not always being done properly in some python types and extension
2294 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2295 all been updated to perform better checks and places in the code that
2296 would previously leak memory on the error path when such an allocation
2297 failed have been fixed.

2303
Benjamin Petersone977ad42008-08-20 01:42:01 +00002304- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2305 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2306
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002307- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2308 version reported by these tools does not necessarily follow the python
2309 version numbering scheme, so the module is less strict when parsing it.
2310
Nick Coghlanf70385a2008-08-18 12:42:46 +00002311- Issue #2235: Added Py3k warnings for types which will become unhashable
2312 under the stricter __hash__ inheritance rules in 3.0. Several types
2313 which did not meet the rules for hash invariants and were already
2314 unhashable in 3.0 have now been explicitly flagged as unhashable in
2315 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2316 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2317
Brett Cannon88f801d2008-08-18 00:46:22 +00002318- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2319 imported into the module but exposed as part of the module's API.
2320

2326
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002327- Issue #3575: Incremental decoder's decode function now takes bytearray
2328 by using 's*' instead of 't#'.
2329
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002330- Issue #2222: Fixed reference leak when occurred os.rename()

Facundo Batistaeb90b782008-08-16 14:44:07 +00002339- Issue #2776: fixed small issue when handling an URL with double slash
2340 after a 302 response in the case of not going through a proxy.
2341
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002342- Issue #2676: in the email package, content-type parsing was hanging on
2343 pathological input because of quadratic or exponential behaviour of a
2344 regular expression.
2345
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002346- Issue #3476: binary buffered reading through the new "io" library is now
2347 thread-safe.
2348
Brett Cannonbf3157b2008-08-14 05:00:03 +00002349- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2350 since mimetools itself is deprecated. Because modules are cached, all
2351 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2352
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002353- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002355- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2356 menu entries were not deleted.
2357
Brett Cannon83e81842008-08-09 23:30:55 +00002358- Copied the implementation of reduce() to _functools.reduce() to have a
2359 version that did not raise a DeprecationWarning under -3.
2360
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002361- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2362 a MemoryError rather than silently stop the iteration.
2363
Guido van Rossum59ce9012008-08-09 14:55:34 +00002364- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2365 to _sre.compile() will now be rejected. This should not affect anybody
2366 since the re.compile() function never generates invalid re-bytecode.
2367
Skip Montanaroa032bf42008-08-08 22:52:51 +00002368- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2369 upon first access it can be automatically initialized from the csv file if
2370 it wasn't initialized during instantiation.
2371
Brett Cannon3aa2a492008-08-06 22:28:09 +00002372- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2373 the reload() built-in has been removed.
2374
Brett Cannon7e30b672008-08-04 21:52:25 +00002375- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002376 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2384 raised an AttributeError.
2385
Benjamin Peterson01a24322008-07-28 23:35:27 +00002386- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002387 asking for a specific length. This problem only affected files opened
2388 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002389
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002390- Issue #3449: Update decimal module to use most recent specification
2391 (v. 1.68) and tests (v. 2.58) from IBM.
2392

2412
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002413- Issue #3394: zipfile.writestr sets external attributes when passed a
2414 file name rather than a ZipInfo instance, so files are extracted with
2415 mode 0600 rather than 000 under Unix.
2416
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002417- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2418 argument in python 2.5, this broke code that subclassed Popen to include its
2419 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2427-------------
2428
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002429- Issue #2235: the C API function PyObject_HashNotImplemented and its
2430 interaction with the tp_hash slot (added in 2.6b2) are now documented
2431
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002432- Issue #643841: The language reference now provides more detailed
2433 coverage of the lookup process for special methods. The disclaimers
2434 regarding lack of coverage of new-style classes have also been
2435 removed, since the coverage is now fairly reasonable.

2439================================
2440
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002441*Release date: 17-Jul-2008*
2442
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002443Core and Builtins
2444-----------------
2445
Georg Brandl3e483f62008-07-16 22:57:41 +00002446- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2447 its methods now allow for items objects that can be converted to
2448 an integer using operator.index().
2449
Mark Dickinson64b7e502008-07-16 09:40:03 +00002450- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2451 produced a ValueError instead of giving the correct float.
2452
Eric Smitha5fa5a22008-07-16 00:11:49 +00002453- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2454 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2455
Mark Dickinson7103aa42008-07-15 19:08:33 +00002456- Issue #3008: the float type has a new instance method 'float.hex'
2457 and a new class method 'float.fromhex' to convert floating-point
2458 numbers to and from hexadecimal strings, respectively.
2459
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002460- Issue #2235: __hash__ is once again inherited by default. To allow
2461 collections.Hashable to remain meaningful in the presence of the
2462 default hash implementation (object.__hash__), it is now possible
2463 to explicit block inheritance of hash by setting __hash__=None at
2464 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2465 level.
2466
Nick Coghlanb028f502008-07-13 14:52:36 +00002467- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2468 the parent module cannot be found while performing an absolute import.
2469 This means that an incorrectly defined __package__ attribute will
2470 now only prevent relative imports in that module rather than causing
2471 all imports from that module to fail.
2472
Nick Coghlan14ff9942008-07-08 14:21:42 +00002473- Issue #2517: Allow unicode messages in Exceptions again by correctly
2474 bypassing the instance dictionary when looking up __unicode__ on
2475 new-style classes.
2476
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002477- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2478 set to a custom object whose write() method happens to install
2479 another file in sys.stdout.
2480
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002481- Issue #3088: Corrected a race condition in classes derived from
2482 threading.local: the first member set by a thread could be saved in
2483 another thread's dictionary.
2484
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002485- Issue #3004: Minor change to slice.indices(): the start and stop
2486 arguments are now treated identically, making the behaviour easier
2487 to describe and understand. For example, slice(None, -10,
2488 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2489 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2490 10, -1).
2491
Georg Brandl278fc502008-07-19 12:46:12 +00002492- Issue #3219: Calling a function with repeated keyword arguments,
2493 f(a=2, a=23), would not cause a syntax error. This was a regression
2494 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002495
Georg Brandl278fc502008-07-19 12:46:12 +00002496- Issue #2862: Make int and float freelist management consistent with
2497 other freelists. Changes their CompactFreeList apis into
2498 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002499

2501-------
2502
Thomas Heller57adf222008-08-14 19:10:48 +00002503- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2504 api functions without holding the GIL, which could lead to a fatal
2505 error when they failed.
2506
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002507- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2516 ForkingPickler.register() to resolve conflict with ctypes.
2517
Vinay Sajip51e65192008-07-18 09:01:10 +00002518- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002519
Thomas Heller880f5292008-07-15 19:39:38 +00002520- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2521 a valid dlerror() message.
2522
Thomas Heller2bad6572008-07-15 17:19:50 +00002523- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2524 incomplete structure was created.
2525
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002526- Issue #3339: dummy_thread.acquire() should not return None.
2527
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002528- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2529
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002530- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002531
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002532- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2533 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002534 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002535 content-length. The problem had been corrected in the 2.4 branch, but never
2536 merged into trunk.
2537
Georg Brandle78fbcc2008-07-05 10:13:36 +00002538- Issue #2663: add filtering capability to shutil.copytree().

2543
2544- Issue #1746: Correct handling of zipfile archive comments (previously
2545 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002546 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002547
Vinay Sajip51e65192008-07-18 09:01:10 +00002548- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002549 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002550
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002551- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00002944 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002945
2946 This is controlled by the configure argument ``--with-universal-archs``:
2947
2948 - ``--with-universal-archs=all``: install 4-way universal
2949
2950 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2951
2952 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2953
2954 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003006- Issue #1631171: Re-implement the 'warnings' module in C (the
3007 original Python code has been kept as backup). This will allow for
3008 using the 'warning's machinery in such places as the parser where
3009 use of pure Python code is not possible. Both the ``showarning()``
3010 and ``formatwarning()`` gain an optional 'line' argument which is
3011 not called by default for backwards-compatibility reasons. Setting
3012 ``warnings.showwarning()`` to an implementation that lacks support
3013 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003076- Issue #2550: The approach used by client/server code for obtaining
3077 ports to listen on in network-oriented tests has been refined in an
3078 effort to facilitate running multiple instances of the entire
3079 regression test suite in parallel without issue.
3080 test_support.bind_port() has been fixed such that it will always
3081 return a unique port -- which wasn't always the case with the
3082 previous implementation, especially if socket options had been set
3083 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3084 new implementation of bind_port() will actually raise an exception
3085 if it is passed an AF_INET/SOCK_STREAM socket with either the
3086 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3087 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3088 the socket it's been passed. This currently only applies to
3089 Windows. This option prevents any other sockets from binding to the
3090 host/port we've bound to, thus removing the possibility of the
3091 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3092 when a second SOCK_STREAM socket binds and accepts to a host/port
3093 that's already been bound by another socket. The optional preferred
3094 port parameter to bind_port() has been removed. Under no
3095 circumstances should tests be hard coding ports!
3096
3097 test_support.find_unused_port() has also been introduced, which will
3098 pass a temporary socket object to bind_port() in order to obtain an
3099 unused port. The temporary socket object is then closed and
3100 deleted, and the port is returned. This method should only be used
3101 for obtaining an unused port in order to pass to an external program
3102 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3103 a parameter to a server-oriented class that doesn't give you direct
3104 access to the underlying socket used.
3105
3106 Finally, test_support.HOST has been introduced, which should be used
3107 for the host argument of any relevant socket calls (i.e. bind and
3108 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003109
3110 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003111 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003112 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3113 test_asynchat and test_socket_ssl.
3114
Georg Brandl3ee81df2008-05-17 18:14:43 +00003115 It is now possible for multiple instances of the regression test
3116 suite to run in parallel without issue.

3382Core and builtins
3383-----------------
3384
Fred Drakea8ee94b2008-03-01 02:45:07 +00003385- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003386 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003387
Georg Brandlad61bc82008-02-23 15:11:18 +00003388- Issue #2067: file.__exit__() now calls subclasses' close() method.
3389
3390- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003391
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003392- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003393 issue 215555 for a discussion.
3394
Eric Smitha73fbe72008-02-23 03:09:44 +00003395- Added the future_builtins module, which contains hex() and oct().
3396 These are the PEP 3127 version of these functions, designed to be
3397 compatible with the hex() and oct() builtins from Python 3.0. They
3398 differ slightly in their output formats from the existing, unchanged
3399 Python 2.6 builtins. The expected usage of the future_builtins
3400 module is:
3401 from future_builtins import hex, oct
3402
Eric Smith7ef40bf2008-02-20 23:34:22 +00003403- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3404 exponents for exponents with absolute value < 100. Follows C99
3405 standard. This is a change on Windows, which would use 3 digits.
3406 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3407 so that any alterations it does to the resulting string will be
3408 available in stringlib/formatter.h (for float.__format__).
3409
Eric Smith5a3c1352008-02-19 13:21:56 +00003410- Implemented PEP 3101, Advanced String Formatting. This adds a new
3411 builtin format(); a format() method for str and unicode; a
3412 __format__() method to object, str, unicode, int, long, float, and
3413 datetime; the class string.Formatter; and the C API
3414 PyObject_Format().
3415
Georg Brandl3ee81df2008-05-17 18:14:43 +00003416- Fixed several potential crashes, all caused by specially crafted
3417 __del__ methods exploiting objects in temporarily inconsistent
3418 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003419
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003420- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003421 prevent a possible crash: an Abstract Base Class would try to access
3422 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003423
Georg Brandl3ee81df2008-05-17 18:14:43 +00003424- Fixed repr() and str() of complex numbers with infinity or nan as
3425 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003426
Georg Brandl3ee81df2008-05-17 18:14:43 +00003427- Clear all free lists during a gc.collect() of the highest generation
3428 in order to allow pymalloc to free more arenas. Python may give back
3429 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003430
Georg Brandl3ee81df2008-05-17 18:14:43 +00003431- Issue #2045: Fix an infinite recursion triggered when printing a
3432 subclass of collections.defaultdict, if its default_factory is set
3433 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003434
Christian Heimesf75dbef2008-02-08 00:11:31 +00003435- Fixed a minor memory leak in dictobject.c. The content of the free
3436 list was not freed on interpreter shutdown.
3437
Georg Brandl3ee81df2008-05-17 18:14:43 +00003438- Limit free list of method and builtin function objects to 256
3439 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003440
Georg Brandl3ee81df2008-05-17 18:14:43 +00003441- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3442 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003443 to compact the internal free lists of pre-allocted ints and floats.
3444
Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3446 calls. Python expected the return type int but the fork familie
3447 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003448
Georg Brandl3ee81df2008-05-17 18:14:43 +00003449- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3450 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003451
Georg Brandl3ee81df2008-05-17 18:14:43 +00003452- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3453 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003454
Georg Brandl3ee81df2008-05-17 18:14:43 +00003455- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3456 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003457
Georg Brandl3ee81df2008-05-17 18:14:43 +00003458- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3459 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003460
Georg Brandl3ee81df2008-05-17 18:14:43 +00003461- Patch #1473257: generator objects gain a gi_code attribute. This is
3462 the same object as the func_code attribute of the function that
3463 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003464
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465- Issue #1920: "while 0" statements were completely removed by the
3466 compiler, even in the presence of an "else" clause, which is
3467 supposed to be run when the condition is false. Now the compiler
3468 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003469
Guido van Rossumeead05f2008-01-24 18:21:02 +00003470- A few crashers fixed: weakref_in_del.py (issue #1377858);
3471 loosing_dict_ref.py (issue #1303614, test67.py);
3472 borrowed_ref_[34].py (not in tracker).
3473
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003474- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003475 suppressed while an extension is loaded by calling SetErrorMode in
3476 dynload_win.c. The error is still reported properly.
3477
Georg Brandl3ee81df2008-05-17 18:14:43 +00003478- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003479 several extension methods and modules do not work without unicode
3480 support.
3481
Georg Brandl26543b12008-01-21 18:36:51 +00003482- Issue #1882: when compiling code from a string, encoding cookies in the
3483 second line of code were not always recognized correctly.
3484
Georg Brandl14404b62008-01-19 19:27:05 +00003485- Issue #1679: "0x" was taken as a valid integer literal.
3486
Georg Brandl6caad7d2008-01-26 14:19:22 +00003487- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003488 added.
3489
Christian Heimesc94e2b52008-01-14 04:13:37 +00003490- sys.float_info / PyFloat_GetInfo: The floating point information
3491 object was converted from a dict to a specialized structseq object.
3492
Georg Brandl3ee81df2008-05-17 18:14:43 +00003493- Patch #1816: Added sys.flags structseq. It exposes the status of
3494 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003495
Georg Brandl3ee81df2008-05-17 18:14:43 +00003496- Objects/structseq.c: Implemented new structseq representation. The
3497 patch makes structseqs (e.g. the return value of os.stat) more
3498 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003499
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500- Patch #1700288: added a type attribute cache that caches method
3501 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003502
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003503- Bug #1776: __import__() no longer accepts filenames on any platform.
3504 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003505
Georg Brandlaed6c662008-01-07 17:25:53 +00003506- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3507
Georg Brandl3ee81df2008-05-17 18:14:43 +00003508- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3509 envvar and sys.dont_write_bytecode attribute. All these can be set
3510 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003511
Georg Brandl3ee81df2008-05-17 18:14:43 +00003512- Improve some exception messages when Windows fails to load an
3513 extension module. Now we get for example '%1 is not a valid Win32
3514 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003515
Georg Brandl3ee81df2008-05-17 18:14:43 +00003516- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003518- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3519 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003520
Christian Heimes0a8143f2007-12-18 23:22:54 +00003521- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003522 and INF. float("nan"), float("inf") and float("-inf") now work on
3523 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Compiler now generates simpler and faster code for dictionary
3526 literals. The oparg for BUILD_MAP now indicates an estimated
3527 dictionary size. There is a new opcode, STORE_MAP, for adding
3528 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003529
Georg Brandl3ee81df2008-05-17 18:14:43 +00003530- Issue #1638: %zd configure test fails on Linux.

3546 running, and if the deallocation of its frames somehow calls the
3547 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003548

3558 file can now be directly executed by passing their name to the
3559 interpreter. The directory/zipfile is automatically inserted as the
3560 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003561
Georg Brandl3ee81df2008-05-17 18:14:43 +00003562- Issue #1265: Fix a problem with sys.settrace, if the tracing
3563 function uses a generator expression when at the same time the
3564 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003565
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003566- sets and frozensets now have an isdisjoint() method.
3567
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003568- optimize the performance of builtin.sum().
3569
Neal Norwitz44f326e2007-10-05 05:29:17 +00003570- Fix warnings found by the new version of the Coverity checker.
3571
Georg Brandl3ee81df2008-05-17 18:14:43 +00003572- The enumerate() builtin function is no longer bounded to sequences
3573 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3574 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003575
Georg Brandl3ee81df2008-05-17 18:14:43 +00003576- Issue #1686386: Tuple's tp_repr did not take into account the
3577 possibility of having a self-referential tuple, which is possible
3578 from C code. Nor did object's tp_str consider that a type's tp_str
3579 could do something that could lead to an inifinite recursion.
3580 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3581 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003582
Georg Brandl3ee81df2008-05-17 18:14:43 +00003583- Issue #1164: It was possible to trigger deadlock when using the
3584 'print' statement to write to a file since the GIL was not released
3585 as needed. Now PyObject_Print() does the right thing along with
3586 various tp_print implementations of the built-in types and those in
3587 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003589- Issue #1147: Exceptions were directly allowing string exceptions in
3590 their throw() method even though string exceptions no longer
3591 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003592
Georg Brandl3ee81df2008-05-17 18:14:43 +00003593- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003596- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003597 PyObject_Call() never calling back out to Python code to trigger
3598 recursion depth updates/checks. Required the creation of a static
3599 RuntimeError instance in case normalizing an exception put the
3600 recursion check value past its limit. Fixes crashers
3601 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003602

Neal Norwitz0ac60192007-05-27 04:08:54 +00003616- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003617 __*__ attributes. (Some already existed, e.g., __doc__ and
3618 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003619
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003620- Add -3 option to the interpreter to warn about features that are
3621 deprecated and will be changed/removed in Python 3.0.
3622

3624 calls.
3625
Collin Winter62903052007-05-18 23:11:24 +00003626- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003627 "except E as target:". This is to provide forwards compatibility
3628 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003629
Brett Cannon229cee22007-05-05 01:34:02 +00003630- Deprecate BaseException.message as per PEP 352.
3631
Georg Brandl3ee81df2008-05-17 18:14:43 +00003632- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003633 inherited from a builtin base.
3634
Vinay Sajip8549ce32007-05-06 17:53:37 +00003635- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003636 setting a plain string, ie don't expand to single letter identifiers.
3637
Raymond Hettinger13936692007-04-11 18:40:58 +00003638- Request #1191699: Slices can now be pickled.
3639
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003640- Request #1193128: str.translate() now allows a None argument for
3641 translations that only remove characters without re-mapping the
3642 remaining characters.
3643
Georg Brandl5cb76c12007-03-21 09:00:39 +00003644- Patch #1682205: a TypeError while unpacking an iterable is no longer
3645 masked by a generic one with the message "unpack non-sequence".
3646

3648
Guido van Rossum143b5642007-03-23 04:58:42 +00003649- Bug #1683368: The object.__init__() and object.__new__() methods are
3650 now stricter in rejecting excess arguments. The only time when
3651 either allows excess arguments is when it is not overridden and the
3652 other one is. For backwards compatibility, when both are
3653 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003654 warning later). Also, type.__init__() insists on the same signature
3655 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003656
Georg Brandl3ee81df2008-05-17 18:14:43 +00003657- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3658 object to complex using its __complex__() method before falling back
3659 to the __float__() method. Therefore, the functions in the cmath
3660 module now can operate on objects that define a __complex__()
3661 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003662
Georg Brandl3ee81df2008-05-17 18:14:43 +00003663- Patch #1623563: allow __class__ assignment for classes with
3664 __slots__. The old and the new class are still required to have the
3665 same slot names.

3678
Georg Brandl7b9c5552007-03-12 14:30:05 +00003679- Bug #1678647: write a newline after printing an exception in any
3680 case, even when converting the value to a string failed.
3681
Georg Brandl871f1bc2007-03-12 13:17:36 +00003682- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003683 its argument, if it exists. If not, it will work like before. This
3684 allows customizing the output of dir() in the presence of a
3685 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003686
Collin Winter276887b2007-03-12 16:11:39 +00003687- Patch #922167: Python no longer segfaults when faced with infinitely
3688 self-recursive reload() calls (as reported by bug #742342).
3689
Georg Brandl3ee81df2008-05-17 18:14:43 +00003690- Patch #1675981: remove unreachable code from ``type.__new__()``

3694 parthensized forms. This means complex(repr(x)) now works instead of
3695 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003696
Georg Brandlaa2321b2007-03-07 00:40:28 +00003697- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003698 makes the filenames the warning module prints much more sensible
3699 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003700
Georg Brandl49aafc92007-03-07 00:34:46 +00003701- Variant of patch #697613: don't exit the interpreter on a SystemExit
3702 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003703 variable is given, but break into the interactive interpreter just
3704 like on other exceptions or normal program exit.

3710 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003711
Georg Brandl0fca97a2007-03-05 22:28:08 +00003712- Patch #1674228: when assigning a slice (old-style), check for the
3713 sq_ass_slice instead of the sq_slice slot.
3714
Georg Brandl3ee81df2008-05-17 18:14:43 +00003715- When printing an unraisable error, don't print exceptions. before
3716 the name. This duplicates the behavior whening normally printing
3717 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003718
Georg Brandl3ee81df2008-05-17 18:14:43 +00003719- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003725- Bug #1377858: Fix the segfaulting of the interpreter when an object
3726 created a weakref on itself during a __del__ call for new-style
3727 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004250 AttributeError instead of an IOError when the server's response
4251 didn't contain a valid HTTP status line.

4340
Georg Brandl3ee81df2008-05-17 18:14:43 +00004341- unittest now verifies more of its assumptions. In particular,
4342 TestCase and TestSuite subclasses (not instances) are no longer
4343 accepted in TestSuite.addTest(). This should cause no
4344 incompatibility since it never made sense with ordinary subclasses

Georg Brandl3ee81df2008-05-17 18:14:43 +00004627- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4628 with RFC 3207 and forgets any knowledge obtained from the server not
4629 obtained from the TLS negotiation itself. Patch contributed by Bill
4630 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004631
Georg Brandl3ee81df2008-05-17 18:14:43 +00004632- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004633 that the SMTP.starttls() caller no longer needs to call ehlo()
4634 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004635 does not claim to support starttls. Adds the
4636 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4717 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4718 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004735 time so that opening a database previously created with the DB_DUP
4736 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4737 opens. Specifically: dictionary assignment to a DB object will
4738 replace all values for a given key when the database allows
4739 duplicate values. DB users should use DB.put(k, v) when they want
4740 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004741

4747 characters with ASCII value less than 32. Also, it correctly quotes
4748 dots only if they occur on a single line, as opposed to the previous
4749 behavior of quoting dots if they are the second character of any
4750 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004751

Georg Brandl3ee81df2008-05-17 18:14:43 +00005086- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5087 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5088 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005089
5090- Patch #1720595: add T_BOOL to the range of structmember types.
5091
5092- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and

5094
Georg Brandl3ee81df2008-05-17 18:14:43 +00005095- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5096 of w# format code incorrectly truncated the length to an int, even
5097 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5098 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005099
Georg Brandl3ee81df2008-05-17 18:14:43 +00005100- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5101 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005103- PEP 3123: Provide forward compatibility with Python 3.0, while
5104 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5105 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005107- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5108 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005109
5110- Patch #1733960: Allow T_LONGLONG to accept ints.
5111
5112- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5113
Christian Heimes000a0742008-01-03 22:16:32 +00005114- Added a new API function ``PyImport_ImportModuleNoBlock``.

5117
5118- Fix some leftovers from the conversion from int to Py_ssize_t
5119 (relevant to strings and sequences of more than 2**31 items).
5120
5121- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5122 outside of pystate.c and should not be necessary.
5123
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5125 absolute imports. In earlier versions they might have used relative
5126 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005127
Georg Brandl3ee81df2008-05-17 18:14:43 +00005128- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5129 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005130
Georg Brandl3ee81df2008-05-17 18:14:43 +00005131- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005138- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5139 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5140 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5141 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005142
Georg Brandl3ee81df2008-05-17 18:14:43 +00005143- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005156- Removed the macfs module. It had been deprecated since Python 2.5.
5157 This lead to the deprecation of macostools.touched() as it relied
5158 solely on macfs and was a no-op under OS X.
