Mark Dickinson476279f2010-01-16 10:44:00 +000029- Issue #7632: Fix various str -> float conversion bugs present in 2.7
30 alpha 2, including: (1) a serious 'wrong output' bug that could
31 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
32 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +000033 strings corresponding to subnormal values, (3) a memory leak for
34 some values large enough to cause overflow, and (4) a number of
35 flaws that could lead to incorrectly rounded results.

120Core and Builtins
121-----------------
122
Benjamin Petersonecdae192010-01-04 00:43:01 +0000123- The __complex__ method is now looked up on the class of instances to make it
124 consistent with other special methods.
125
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000126- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
127 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
128
Mark Dickinson1b34d252010-01-01 17:27:30 +0000129- Issue #5080: A number of functions and methods previously produced a
130 DeprecationWarning when passed a float argument where an integer was
131 expected. These functions and methods now raise TypeError instead.
132 The majority of the effects of this change are in the extension
133 modules, but some core functions and methods are affected: notably
134 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
135 methods.
136
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000137- Issue #7604: Deleting an unset slotted attribute did not raise an

145
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000146- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
147 used to drop the time part of the result.
148
Mark Dickinson46572832009-12-27 14:55:57 +0000149- Issue #1811: improve accuracy and cross-platform consistency for
150 true division of integers: the result of a/b is now correctly
151 rounded for ints a and b (at least on IEEE 754 platforms), and in
152 particular does not depend on the internal representation of a long.
153
Ezio Melottif84caf42009-12-24 22:25:17 +0000154- Issue #6108: unicode(exception) and str(exception) should return the same
155 message when only __str__ (and not __unicode__) is overridden in the subclass.
156
Ronald Oussoren92919a62009-12-24 13:30:58 +0000157- Issue #6834: replace the implementation for the 'python' and 'pythonw'
158 executables on OSX.
159

161 ``arch -ppc python`` will start a universal binary version of python
162 in PPC mode (unlike previous releases).
163
R. David Murray0a0a1a82009-12-14 16:28:26 +0000164- Issue #1680159: unicode coercion during an 'in' operation no longer masks
165 the underlying error when the coercion fails for the left hand operand.
166
Benjamin Peterson4895af42009-12-13 16:36:53 +0000167- Issue #7491: Metaclass's __cmp__ method was ignored.
168
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000169- Issue #7466: segmentation fault when the garbage collector is called

179
Antoine Pitrou80157252010-01-08 19:20:17 +0000180- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
181 renaming of `cPickle` to `pickle`. The warning was annoying since there's
182 no alternative to cPickle if you care about performance. Patch by Florent
183 Xicluna.
184
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000185- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

217 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
218 the same as passing no argument.
219
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000220- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

Mark Dickinsonb678de82009-11-19 18:41:49 +0000312- Issue #7117: repr(x) for a float x returns a result based on the
313 shortest decimal string that's guaranteed to round back to x under
314 correct rounding (with round-half-to-even rounding mode).
315 Previously it gave a string based on rounding x to 17 decimal digits.
316 repr(x) for a complex number behaves similarly. On platforms where
317 the correctly-rounded strtod and dtoa code is not supported (see below),
318 repr is unchanged.
319
320- Issue #7117: On almost all platforms: float-to-string and
321 string-to-float conversions within Python are now correctly rounded.
322 Places these conversions occur include: str for floats and complex
323 numbers; the float and complex constructors; old-style and new-style
324 numeric formatting; serialization and deserialization of floats and
325 complex numbers using marshal, pickle and json; parsing of float and
326 imaginary literals in Python code; Decimal-to-float conversion.
327
328 The conversions use a Python-adapted version of David Gay's
329 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
330 functions. This code is supported on Windows, and on Unix-like
331 platforms using gcc, icc or suncc as the C compiler. There may be a
332 small number of platforms on which correct operation of this code
333 cannot be guaranteed, so the code is not used: notably, this applies
334 to platforms where the C double format is not IEEE 754 binary64, and
335 to platforms on x86 hardware where the x87 FPU is set to 64-bit
336 precision and Python's configure script is unable to determine how
337 to change the FPU precision. On these platforms conversions use the
338 platform strtod and dtoa, as before.
339
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000340- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000341 now uses the correctly-rounded string <-> float conversions
342 described above (when available), and so produces correctly rounded
343 results that will display nicely under the float repr. There are
344 two related small changes: (1) round now accepts any class with an
345 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000346 floats for the second argument), and (2) an excessively large second
347 integer argument (e.g., round(1.234, 10**100)) no longer raises an
348 exception.

614
Georg Brandl29c6a282009-04-05 20:23:13 +0000615- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000616 were suppressing all exceptions. These include list(), filter(), map(),
617 zip(), and bytearray().
618
Benjamin Peterson596d3062009-01-19 15:42:23 +0000619- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

626
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000627- Issue #4935: The overflow checking code in the expandtabs() method common
628 to str, bytes and bytearray could be optimized away by the compiler, letting
629 the interpreter segfault instead of raising an error.
630
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000631- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000638- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
639 collecting the oldest generation) so that allocating lots of objects without
640 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000641 Martin von Löwis at

645
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000646- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
647 an existing .py counterpart, override the co_filename attributes of all
648 code objects if the original filename is obsolete (which can happen if the
649 file has been renamed, moved, or if it is accessed through different paths).
650 Patch by Ziga Seilnacht and Jean-Paul Calderone.

662
Benjamin Peterson7af65562008-12-29 17:56:58 +0000663- Issue #4764: With io.open, IOError.filename is set when trying to open a

686
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000687- Issue #4597: Fixed several opcodes that weren't always propagating
688 exceptions.
689
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000690- Issue #4445: Replace "sizeof(PyStringObject)" with
691 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
692 str instances. On a typical machine this saves 3 bytes of memory
693 (on average) per string allocation.
694
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000695- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
696 interpreter to abort ("Fatal Python error: Could not reset the stack!")
697 instead of throwing a MemoryError.
698
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000699- Issue #3689: The list reversed iterator now supports __length_hint__
700 instead of __len__. Behavior now matches other reversed iterators.
701
Benjamin Petersonc078f922008-11-21 22:27:24 +0000702- Issue #4367: Python would segfault during compiling when the unicodedata

704
Vinay Sajip213faca2008-12-03 23:22:58 +0000705- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000706 method on file objects with closefd=False. The file descriptor is still
707 kept open but the file object behaves like a closed file. The ``FileIO``
708 object also got a new readonly attribute ``closefd``.
709
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000710- Issue #4348: Some bytearray methods returned that didn't cause any change to
711 the bytearray, returned the same bytearray instead of a copy.
712
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000713- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

718
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000719- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

721
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000722- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
723 method does not return iterators for the 4th and 5th items.
724
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000725- Issue #4209: Enabling unicode_literals and the print_function in the same
726 __future__ import didn't work.
727
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000728- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000729 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000731- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
732 returned a path longer than MAX_PATH. (But It's doubtful this code path is
733 really executed because I cannot move to such directory on win2k)
734
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000735- Issue #4069: When set.remove(element) is used with a set element, the element
736 is temporarily replaced with an equivalent frozenset. But the eventual
737 KeyError would always report the empty frozenset([]) as the missing key. Now
738 it correctly refers to the initial element.
739
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000740- Issue #4509: Various issues surrounding resize of bytearray objects to

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000755- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
756 returned them on 64bit platforms.
757
Walter Dörwalded960ac2009-05-03 22:36:33 +0000758- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
759 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
760 step. This avoids problems with counting UTF-8 bytes that ignores the effect
761 of using the replace error handler in PyUnicode_DecodeUTF8().
762
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000763- Issue #3739: The unicode-internal encoder now reports the number of characters
764 consumed like any other encoder (instead of the number of bytes).
765
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000766- Issue #2422: When compiled with the ``--with-valgrind`` option, the
767 pymalloc allocator will be automatically disabled when running under
768 Valgrind. This gives improved memory leak detection when running
769 under Valgrind, while taking advantage of pymalloc at other times.

2150
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002151- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2152 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2153 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2154 ``printf`` function, whereas PyString_FromFormat has an independent
2155 implementation and uses "%zd" on all platforms for size_t values.
2156 This makes a difference on win64, where ``printf`` needs "%Id" to display
2157 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002159- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2163 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002167- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002173 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002174 was correctly parsed but parsing of subsequent arguments failed.
2175
Vinay Sajip35e3b032008-09-01 14:33:59 +00002176- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002177 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2178 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2179 when given a tuple of classes as second argument, were looking up
2180 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2181 type object.
2182
Neal Norwitz18aa3882008-08-24 05:04:52 +00002183- Fix crashes on memory allocation failure found with failmalloc.

Jesse Noller438195f2009-01-18 21:04:36 +00002276- Issue #4301: Patch the logging module to add processName support, remove
2277 _check_logger_class from multiprocessing.
2278
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002279- Issue #2975: When compiling several extension modules with Visual Studio 2008
2280 from the same python interpreter, some environment variables would grow
2281 without limit.
2282
Benjamin Peterson37346b22008-08-23 20:27:43 +00002283- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2284 exploitation of poor argument checking.
2285

2299 wrapper for warnings.catch_warnings() that makes it easier to check
2300 that expected warning messages are being reported.
2301
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002302- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002320What's New in Python 2.6 beta 3?
2321================================
2322
Barry Warsaw07a4a382008-08-21 01:15:08 +00002323*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002324
2325Core and Builtins
2326-----------------
2327
Guido van Rossumf8402962008-08-20 15:01:50 +00002328- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2329 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2330 extensions do not automatically benefit from the class attribute
2331 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2332 to their tp_flags field if they care. This is a backwards
2333 compatibility feature; in 3.0, all types will use the cache by
2334 default.
2335
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002336- Keyword arguments can now follow starred arguments. (``f(a, *args,
2337 keyword=23)`` is now valid syntax.)
2338
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002339- ctypes function pointers that are COM methods have a boolean True
2340 value again.
2341
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002342- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2343 by denying s# to parse objects that have a releasebuffer procedure,
2344 and introducing s*.
2345
Georg Brandl1e13ea92008-08-11 09:07:59 +00002346- Issue #3537: Fix an assertion failure when an empty but presized dict
2347 object was stored in the freelist.
2348
Mark Dickinsonb6467572008-08-04 21:30:09 +00002349- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2350 ValueError consistently across platforms.
2351
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002352- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2353 (64bit Unix, for example), unichr() would truncate its argument and return
2354 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2355
Neal Norwitze7d8be82008-07-31 17:17:14 +00002356- Apply security patches from Apple.
2357
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002358- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2359 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2360
Antoine Pitrou92f82162008-07-25 22:22:08 +00002361- Issue #1819: function calls with several named parameters are now on
2362 average 35% faster (as measured by pybench).
2363
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002364- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2365 the python debugger steps into a class statement: the free variables (local
2366 variables defined in an outer scope) would be deleted from the outer scope.
2367
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002368- Issue #2620: Overflow checking when allocating or reallocating memory
2369 was not always being done properly in some python types and extension
2370 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2371 all been updated to perform better checks and places in the code that
2372 would previously leak memory on the error path when such an allocation
2373 failed have been fixed.
2374
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002375Library
2376-------
2377
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002378- Issue #3612: Added some missing basic types in ctypes.wintypes.
2379
Benjamin Petersone977ad42008-08-20 01:42:01 +00002380- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2381 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2382
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002383- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2384 version reported by these tools does not necessarily follow the python
2385 version numbering scheme, so the module is less strict when parsing it.
2386
Nick Coghlanf70385a2008-08-18 12:42:46 +00002387- Issue #2235: Added Py3k warnings for types which will become unhashable
2388 under the stricter __hash__ inheritance rules in 3.0. Several types
2389 which did not meet the rules for hash invariants and were already
2390 unhashable in 3.0 have now been explicitly flagged as unhashable in
2391 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2392 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2393
Brett Cannon88f801d2008-08-18 00:46:22 +00002394- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2395 imported into the module but exposed as part of the module's API.
2396
Brett Cannon7b96f072008-08-18 00:41:11 +00002397- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2398
Brett Cannon46225e72008-08-18 00:36:52 +00002399- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002401- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2402
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002403- Issue #3575: Incremental decoder's decode function now takes bytearray
2404 by using 's*' instead of 't#'.
2405
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002406- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002407 fails unicode conversion on 2nd parameter. (windows only)
2408
Facundo Batista94f243a2008-08-17 03:38:39 +00002409- Issue 2464. urllib2 now supports a malformation in the URL received
2410 in a redirect.
2411
Brett Cannonabe423e2008-08-16 21:47:07 +00002412- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002413 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002414
Facundo Batistaeb90b782008-08-16 14:44:07 +00002415- Issue #2776: fixed small issue when handling an URL with double slash
2416 after a 302 response in the case of not going through a proxy.
2417
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002418- Issue #2676: in the email package, content-type parsing was hanging on
2419 pathological input because of quadratic or exponential behaviour of a
2420 regular expression.
2421
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002422- Issue #3476: binary buffered reading through the new "io" library is now
2423 thread-safe.
2424
Brett Cannonbf3157b2008-08-14 05:00:03 +00002425- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2426 since mimetools itself is deprecated. Because modules are cached, all
2427 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2428
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002429- Issue #3134: shutil referenced undefined WindowsError symbol.
2430
Robert Schuppenies14646332008-08-10 11:01:53 +00002431- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2432 menu entries were not deleted.
2433
Brett Cannon83e81842008-08-09 23:30:55 +00002434- Copied the implementation of reduce() to _functools.reduce() to have a
2435 version that did not raise a DeprecationWarning under -3.
2436
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002437- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2438 a MemoryError rather than silently stop the iteration.
2439
Guido van Rossum59ce9012008-08-09 14:55:34 +00002440- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2441 to _sre.compile() will now be rejected. This should not affect anybody
2442 since the re.compile() function never generates invalid re-bytecode.
2443
Skip Montanaroa032bf42008-08-08 22:52:51 +00002444- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2445 upon first access it can be automatically initialized from the csv file if
2446 it wasn't initialized during instantiation.
2447
Brett Cannon3aa2a492008-08-06 22:28:09 +00002448- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2449 the reload() built-in has been removed.
2450
Brett Cannon7e30b672008-08-04 21:52:25 +00002451- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002452 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2460 raised an AttributeError.
2461
Benjamin Peterson01a24322008-07-28 23:35:27 +00002462- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002463 asking for a specific length. This problem only affected files opened
2464 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002465
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002466- Issue #3449: Update decimal module to use most recent specification
2467 (v. 1.68) and tests (v. 2.58) from IBM.
2468

2477
2478- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2479 invalid arguments.
2480
2481- Issue #3302: Fix several crashes when calling locale's gettext functions
2482 with None arguments.

2488
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002489- Issue #3394: zipfile.writestr sets external attributes when passed a
2490 file name rather than a ZipInfo instance, so files are extracted with
2491 mode 0600 rather than 000 under Unix.
2492
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002493- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2494 argument in python 2.5, this broke code that subclassed Popen to include its
2495 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002505- Issue #2235: the C API function PyObject_HashNotImplemented and its
2506 interaction with the tp_hash slot (added in 2.6b2) are now documented
2507
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002508- Issue #643841: The language reference now provides more detailed
2509 coverage of the lookup process for special methods. The disclaimers
2510 regarding lack of coverage of new-style classes have also been
2511 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002519Core and Builtins
2520-----------------
2521
Georg Brandl3e483f62008-07-16 22:57:41 +00002522- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2523 its methods now allow for items objects that can be converted to
2524 an integer using operator.index().
2525
Mark Dickinson64b7e502008-07-16 09:40:03 +00002526- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2527 produced a ValueError instead of giving the correct float.
2528
Eric Smitha5fa5a22008-07-16 00:11:49 +00002529- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2530 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2531
Mark Dickinson7103aa42008-07-15 19:08:33 +00002532- Issue #3008: the float type has a new instance method 'float.hex'
2533 and a new class method 'float.fromhex' to convert floating-point
2534 numbers to and from hexadecimal strings, respectively.
2535
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002536- Issue #2235: __hash__ is once again inherited by default. To allow
2537 collections.Hashable to remain meaningful in the presence of the
2538 default hash implementation (object.__hash__), it is now possible
2539 to explicit block inheritance of hash by setting __hash__=None at
2540 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2541 level.
2542
Nick Coghlanb028f502008-07-13 14:52:36 +00002543- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2544 the parent module cannot be found while performing an absolute import.
2545 This means that an incorrectly defined __package__ attribute will
2546 now only prevent relative imports in that module rather than causing
2547 all imports from that module to fail.
2548
Nick Coghlan14ff9942008-07-08 14:21:42 +00002549- Issue #2517: Allow unicode messages in Exceptions again by correctly
2550 bypassing the instance dictionary when looking up __unicode__ on
2551 new-style classes.
2552
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002553- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2554 set to a custom object whose write() method happens to install
2555 another file in sys.stdout.

2559 another thread's dictionary.
2560
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002561- Issue #3004: Minor change to slice.indices(): the start and stop
2562 arguments are now treated identically, making the behaviour easier
2563 to describe and understand. For example, slice(None, -10,
2564 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2565 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2566 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00003020 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003021
3022 This is controlled by the configure argument ``--with-universal-archs``:

3025
3026 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3027
3028 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

3069 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003082- Issue #1631171: Re-implement the 'warnings' module in C (the
3083 original Python code has been kept as backup). This will allow for
3084 using the 'warning's machinery in such places as the parser where
3085 use of pure Python code is not possible. Both the ``showarning()``
3086 and ``formatwarning()`` gain an optional 'line' argument which is
3087 not called by default for backwards-compatibility reasons. Setting
3088 ``warnings.showwarning()`` to an implementation that lacks support
3089 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003152- Issue #2550: The approach used by client/server code for obtaining
3153 ports to listen on in network-oriented tests has been refined in an
3154 effort to facilitate running multiple instances of the entire
3155 regression test suite in parallel without issue.
3156 test_support.bind_port() has been fixed such that it will always
3157 return a unique port -- which wasn't always the case with the
3158 previous implementation, especially if socket options had been set
3159 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3160 new implementation of bind_port() will actually raise an exception
3161 if it is passed an AF_INET/SOCK_STREAM socket with either the
3162 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3163 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3164 the socket it's been passed. This currently only applies to
3165 Windows. This option prevents any other sockets from binding to the
3166 host/port we've bound to, thus removing the possibility of the
3167 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3168 when a second SOCK_STREAM socket binds and accepts to a host/port
3169 that's already been bound by another socket. The optional preferred
3170 port parameter to bind_port() has been removed. Under no
3171 circumstances should tests be hard coding ports!
3172
3173 test_support.find_unused_port() has also been introduced, which will
3174 pass a temporary socket object to bind_port() in order to obtain an
3175 unused port. The temporary socket object is then closed and
3176 deleted, and the port is returned. This method should only be used
3177 for obtaining an unused port in order to pass to an external program
3178 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3179 a parameter to a server-oriented class that doesn't give you direct
3180 access to the underlying socket used.
3181
3182 Finally, test_support.HOST has been introduced, which should be used
3183 for the host argument of any relevant socket calls (i.e. bind and
3184 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003185
3186 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003187 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003188 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3189 test_asynchat and test_socket_ssl.
3190
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191 It is now possible for multiple instances of the regression test
3192 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00003461- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003462 644. The mode is now inherited from the py file.

3470
Eric Smitha73fbe72008-02-23 03:09:44 +00003471- Added the future_builtins module, which contains hex() and oct().
3472 These are the PEP 3127 version of these functions, designed to be
3473 compatible with the hex() and oct() builtins from Python 3.0. They
3474 differ slightly in their output formats from the existing, unchanged
3475 Python 2.6 builtins. The expected usage of the future_builtins
3476 module is:
3477 from future_builtins import hex, oct
3478
Eric Smith7ef40bf2008-02-20 23:34:22 +00003479- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3480 exponents for exponents with absolute value < 100. Follows C99
3481 standard. This is a change on Windows, which would use 3 digits.
3482 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3483 so that any alterations it does to the resulting string will be
3484 available in stringlib/formatter.h (for float.__format__).
3485
Eric Smith5a3c1352008-02-19 13:21:56 +00003486- Implemented PEP 3101, Advanced String Formatting. This adds a new
3487 builtin format(); a format() method for str and unicode; a
3488 __format__() method to object, str, unicode, int, long, float, and
3489 datetime; the class string.Formatter; and the C API
3490 PyObject_Format().
3491
Georg Brandl3ee81df2008-05-17 18:14:43 +00003492- Fixed several potential crashes, all caused by specially crafted
3493 __del__ methods exploiting objects in temporarily inconsistent
3494 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003495
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003496- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003497 prevent a possible crash: an Abstract Base Class would try to access
3498 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003499

Georg Brandl3ee81df2008-05-17 18:14:43 +00003503- Clear all free lists during a gc.collect() of the highest generation
3504 in order to allow pymalloc to free more arenas. Python may give back
3505 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003506
Georg Brandl3ee81df2008-05-17 18:14:43 +00003507- Issue #2045: Fix an infinite recursion triggered when printing a
3508 subclass of collections.defaultdict, if its default_factory is set
3509 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003510
Christian Heimesf75dbef2008-02-08 00:11:31 +00003511- Fixed a minor memory leak in dictobject.c. The content of the free
3512 list was not freed on interpreter shutdown.
3513
Georg Brandl3ee81df2008-05-17 18:14:43 +00003514- Limit free list of method and builtin function objects to 256
3515 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003516
Georg Brandl3ee81df2008-05-17 18:14:43 +00003517- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3518 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003519 to compact the internal free lists of pre-allocted ints and floats.
3520
Georg Brandl3ee81df2008-05-17 18:14:43 +00003521- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3522 calls. Python expected the return type int but the fork familie
3523 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3526 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003527
Georg Brandl3ee81df2008-05-17 18:14:43 +00003528- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3529 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003534- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3535 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003536
Georg Brandl3ee81df2008-05-17 18:14:43 +00003537- Patch #1473257: generator objects gain a gi_code attribute. This is
3538 the same object as the func_code attribute of the function that
3539 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003540
Georg Brandl3ee81df2008-05-17 18:14:43 +00003541- Issue #1920: "while 0" statements were completely removed by the
3542 compiler, even in the presence of an "else" clause, which is
3543 supposed to be run when the condition is false. Now the compiler
3544 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003545
Guido van Rossumeead05f2008-01-24 18:21:02 +00003546- A few crashers fixed: weakref_in_del.py (issue #1377858);
3547 loosing_dict_ref.py (issue #1303614, test67.py);
3548 borrowed_ref_[34].py (not in tracker).
3549
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003550- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003551 suppressed while an extension is loaded by calling SetErrorMode in
3552 dynload_win.c. The error is still reported properly.
3553
Georg Brandl3ee81df2008-05-17 18:14:43 +00003554- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003555 several extension methods and modules do not work without unicode
3556 support.
3557
Georg Brandl26543b12008-01-21 18:36:51 +00003558- Issue #1882: when compiling code from a string, encoding cookies in the
3559 second line of code were not always recognized correctly.
3560
Georg Brandl14404b62008-01-19 19:27:05 +00003561- Issue #1679: "0x" was taken as a valid integer literal.
3562
Georg Brandl6caad7d2008-01-26 14:19:22 +00003563- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003564 added.
3565
Christian Heimesc94e2b52008-01-14 04:13:37 +00003566- sys.float_info / PyFloat_GetInfo: The floating point information
3567 object was converted from a dict to a specialized structseq object.
3568
Georg Brandl3ee81df2008-05-17 18:14:43 +00003569- Patch #1816: Added sys.flags structseq. It exposes the status of
3570 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003571
Georg Brandl3ee81df2008-05-17 18:14:43 +00003572- Objects/structseq.c: Implemented new structseq representation. The
3573 patch makes structseqs (e.g. the return value of os.stat) more
3574 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003575
Georg Brandl3ee81df2008-05-17 18:14:43 +00003576- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003588- Improve some exception messages when Windows fails to load an
3589 extension module. Now we get for example '%1 is not a valid Win32
3590 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003591

Georg Brandl3ee81df2008-05-17 18:14:43 +00003598 and INF. float("nan"), float("inf") and float("-inf") now work on
3599 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003600
Georg Brandl3ee81df2008-05-17 18:14:43 +00003601- Compiler now generates simpler and faster code for dictionary
3602 literals. The oparg for BUILD_MAP now indicates an estimated
3603 dictionary size. There is a new opcode, STORE_MAP, for adding
3604 entries to the dictionary.

3629
Georg Brandl3ee81df2008-05-17 18:14:43 +00003630- Issue #1460: The utf-7 incremental decoder did not accept truncated
3631 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003632
Georg Brandl3ee81df2008-05-17 18:14:43 +00003633- Patch #1739468: Directories and zipfiles containing a __main__.py
3634 file can now be directly executed by passing their name to the
3635 interpreter. The directory/zipfile is automatically inserted as the
3636 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003637
Georg Brandl3ee81df2008-05-17 18:14:43 +00003638- Issue #1265: Fix a problem with sys.settrace, if the tracing
3639 function uses a generator expression when at the same time the
3640 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003641
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003642- sets and frozensets now have an isdisjoint() method.
3643
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003644- optimize the performance of builtin.sum().
3645
Neal Norwitz44f326e2007-10-05 05:29:17 +00003646- Fix warnings found by the new version of the Coverity checker.
3647
Georg Brandl3ee81df2008-05-17 18:14:43 +00003648- The enumerate() builtin function is no longer bounded to sequences
3649 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3650 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003651
Georg Brandl3ee81df2008-05-17 18:14:43 +00003652- Issue #1686386: Tuple's tp_repr did not take into account the
3653 possibility of having a self-referential tuple, which is possible
3654 from C code. Nor did object's tp_str consider that a type's tp_str
3655 could do something that could lead to an inifinite recursion.
3656 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3657 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003658
Georg Brandl3ee81df2008-05-17 18:14:43 +00003659- Issue #1164: It was possible to trigger deadlock when using the
3660 'print' statement to write to a file since the GIL was not released
3661 as needed. Now PyObject_Print() does the right thing along with
3662 various tp_print implementations of the built-in types and those in
3663 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003664
Georg Brandl3ee81df2008-05-17 18:14:43 +00003665- Issue #1147: Exceptions were directly allowing string exceptions in
3666 their throw() method even though string exceptions no longer
3667 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003668
Georg Brandl3ee81df2008-05-17 18:14:43 +00003669- Issue #1096: Prevent a segfault from getting the repr of a very
3670 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003671
Brett Cannon1e534b52007-09-07 04:18:30 +00003672- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003673 PyObject_Call() never calling back out to Python code to trigger
3674 recursion depth updates/checks. Required the creation of a static
3675 RuntimeError instance in case normalizing an exception put the
3676 recursion check value past its limit. Fixes crashers
3677 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003678

Neal Norwitz0ac60192007-05-27 04:08:54 +00003692- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003693 __*__ attributes. (Some already existed, e.g., __doc__ and
3694 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003695
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003696- Add -3 option to the interpreter to warn about features that are
3697 deprecated and will be changed/removed in Python 3.0.
3698
Georg Brandl2134e752007-05-21 20:34:16 +00003699- Patch #1686487: you can now pass any mapping after '**' in function
3700 calls.
3701
Collin Winter62903052007-05-18 23:11:24 +00003702- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003703 "except E as target:". This is to provide forwards compatibility
3704 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003705
Brett Cannon229cee22007-05-05 01:34:02 +00003706- Deprecate BaseException.message as per PEP 352.
3707
Georg Brandl3ee81df2008-05-17 18:14:43 +00003708- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003709 inherited from a builtin base.
3710
Vinay Sajip8549ce32007-05-06 17:53:37 +00003711- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003712 setting a plain string, ie don't expand to single letter identifiers.
3713
Raymond Hettinger13936692007-04-11 18:40:58 +00003714- Request #1191699: Slices can now be pickled.
3715
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003716- Request #1193128: str.translate() now allows a None argument for
3717 translations that only remove characters without re-mapping the
3718 remaining characters.
3719
Georg Brandl5cb76c12007-03-21 09:00:39 +00003720- Patch #1682205: a TypeError while unpacking an iterable is no longer
3721 masked by a generic one with the message "unpack non-sequence".
3722
Neal Norwitzaa754b72007-03-21 06:39:48 +00003723- Remove unused file Python/fmod.c.
3724
Guido van Rossum143b5642007-03-23 04:58:42 +00003725- Bug #1683368: The object.__init__() and object.__new__() methods are
3726 now stricter in rejecting excess arguments. The only time when
3727 either allows excess arguments is when it is not overridden and the
3728 other one is. For backwards compatibility, when both are
3729 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003730 warning later). Also, type.__init__() insists on the same signature
3731 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003732
Georg Brandl3ee81df2008-05-17 18:14:43 +00003733- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3734 object to complex using its __complex__() method before falling back
3735 to the __float__() method. Therefore, the functions in the cmath
3736 module now can operate on objects that define a __complex__()
3737 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003738
Georg Brandl3ee81df2008-05-17 18:14:43 +00003739- Patch #1623563: allow __class__ assignment for classes with
3740 __slots__. The old and the new class are still required to have the
3741 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003742
Georg Brandl3ee81df2008-05-17 18:14:43 +00003743- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003746- Patch #1462488: Python no longer segfaults when
3747 ``object.__reduce_ex__()`` is called with an object that is faking
3748 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003749
Georg Brandl3ee81df2008-05-17 18:14:43 +00003750- Patch #1680015: Don't modify __slots__ tuple if it contains an
3751 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00003753- Patch #1444529: the builtin compile() now accepts keyword arguments.
3754
Georg Brandl7b9c5552007-03-12 14:30:05 +00003755- Bug #1678647: write a newline after printing an exception in any
3756 case, even when converting the value to a string failed.
3757
Georg Brandl871f1bc2007-03-12 13:17:36 +00003758- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003759 its argument, if it exists. If not, it will work like before. This
3760 allows customizing the output of dir() in the presence of a
3761 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003762
Collin Winter276887b2007-03-12 16:11:39 +00003763- Patch #922167: Python no longer segfaults when faced with infinitely
3764 self-recursive reload() calls (as reported by bug #742342).
3765
Georg Brandl3ee81df2008-05-17 18:14:43 +00003766- Patch #1675981: remove unreachable code from ``type.__new__()``
3767 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003769- Patch #1491866: change the complex() constructor to allow
3770 parthensized forms. This means complex(repr(x)) now works instead of
3771 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003772
Georg Brandlaa2321b2007-03-07 00:40:28 +00003773- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003774 makes the filenames the warning module prints much more sensible
3775 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003776
Georg Brandl49aafc92007-03-07 00:34:46 +00003777- Variant of patch #697613: don't exit the interpreter on a SystemExit
3778 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003779 variable is given, but break into the interactive interpreter just
3780 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003785- Bug #1674503: close the file opened by execfile() in an error
3786 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003787
Georg Brandl0fca97a2007-03-05 22:28:08 +00003788- Patch #1674228: when assigning a slice (old-style), check for the
3789 sq_ass_slice instead of the sq_slice slot.
3790
Georg Brandl3ee81df2008-05-17 18:14:43 +00003791- When printing an unraisable error, don't print exceptions. before
3792 the name. This duplicates the behavior whening normally printing
3793 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003794
Georg Brandl3ee81df2008-05-17 18:14:43 +00003795- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003801- Bug #1377858: Fix the segfaulting of the interpreter when an object
3802 created a weakref on itself during a __del__ call for new-style
3803 classes (classic classes still have the bug).

3850
Armin Rigo7ccbca92006-10-04 12:17:45 +00003851- A number of places, including integer negation and absolute value,
3852 were fixed to not rely on undefined behaviour of the C compiler
3853 anymore.

4359
Georg Brandl92a6bae2007-03-13 17:43:32 +00004360- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004361 are set for invalid interpolation sequences that would lead to

4418 TestCase and TestSuite subclasses (not instances) are no longer
4419 accepted in TestSuite.addTest(). This should cause no
4420 incompatibility since it never made sense with ordinary subclasses
4421 -- the failure just occurred later, with a more cumbersome
4422 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004703- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4704 with RFC 3207 and forgets any knowledge obtained from the server not
4705 obtained from the TLS negotiation itself. Patch contributed by Bill
4706 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004707
Georg Brandl3ee81df2008-05-17 18:14:43 +00004708- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004709 that the SMTP.starttls() caller no longer needs to call ehlo()
4710 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004711 does not claim to support starttls. Adds the
4712 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4793 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4794 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004811 time so that opening a database previously created with the DB_DUP
4812 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4813 opens. Specifically: dictionary assignment to a DB object will
4814 replace all values for a given key when the database allows
4815 duplicate values. DB users should use DB.put(k, v) when they want
4816 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004817

4823 characters with ASCII value less than 32. Also, it correctly quotes
4824 dots only if they occur on a single line, as opposed to the previous
4825 behavior of quoting dots if they are the second character of any
4826 line.

5097 default, this option is turned-off. It should only be enabled in
5098 debugged, performance critical applications.

5149-----
5150
Georg Brandl3ee81df2008-05-17 18:14:43 +00005151- Unified naming convention for free lists and their limits. All free
5152 lists in Object/ are named ``free_list``, the counter ``numfree``
5153 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5154 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005155
Georg Brandl3ee81df2008-05-17 18:14:43 +00005156- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5157 to ``PyTuple_SetItem``, it can be used to populate a brand new
5158 frozenset; but it does not steal a reference to the added item.

5170
Georg Brandl3ee81df2008-05-17 18:14:43 +00005171- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5172 of w# format code incorrectly truncated the length to an int, even
5173 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5174 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005175
Georg Brandl3ee81df2008-05-17 18:14:43 +00005176- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5194- Fix some leftovers from the conversion from int to Py_ssize_t
5195 (relevant to strings and sequences of more than 2**31 items).
5196
5197- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5198 outside of pystate.c and should not be necessary.
5199
Georg Brandl3ee81df2008-05-17 18:14:43 +00005200- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5201 absolute imports. In earlier versions they might have used relative
5202 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005203
Georg Brandl3ee81df2008-05-17 18:14:43 +00005204- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5205 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005206
Georg Brandl3ee81df2008-05-17 18:14:43 +00005207- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5215 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5216 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5217 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005218

Georg Brandl3ee81df2008-05-17 18:14:43 +00005232- Removed the macfs module. It had been deprecated since Python 2.5.
5233 This lead to the deprecation of macostools.touched() as it relied
5234 solely on macfs and was a no-op under OS X.
