Victor Stinner66644262010-03-10 22:30:19 +000015- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
16 (SIGINT). If an error occurs while importing the site module, the error is
17 printed and Python exits. Initialize the GIL before importing the site
18 module.

26 classes.

R. David Murray4617e502010-03-08 02:04:06 +000028- Issue #7143: get_payload used to strip any trailing newline from a
29 base64 transfer-encoded payload *after* decoding it; it no longer does.
30 This is a behavior change, so email's minor version number is now
31 bumped, to version 4.0.2, for the 2.7 release.

36- Issue #1530559: When passing a non-integer argument to struct.pack
37 with *any* integer format code (one of 'bBhHiIlLqQ'), struct.pack
38 attempts to use the argument's __int__ method to convert to an
39 integer before packing. It also produces a DeprecationWarning in
40 this case. (In Python 2.6, the behaviour was inconsistent: __int__
41 was used for some integer codes but not for others, and the set of
42 integer codes for which it was used differed between native packing
43 and standard packing.)

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000371What's New in Python 2.7 alpha 2?
372=================================

Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000374*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000375
376Core and Builtins
377-----------------
378
Benjamin Petersonecdae192010-01-04 00:43:01 +0000379- The __complex__ method is now looked up on the class of instances to make it
380 consistent with other special methods.
381
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000382- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
383 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
384
Mark Dickinson1b34d252010-01-01 17:27:30 +0000385- Issue #5080: A number of functions and methods previously produced a
386 DeprecationWarning when passed a float argument where an integer was
387 expected. These functions and methods now raise TypeError instead.
388 The majority of the effects of this change are in the extension
389 modules, but some core functions and methods are affected: notably
390 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
391 methods.
392
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000393- Issue #7604: Deleting an unset slotted attribute did not raise an
394 AttributeError.
395
Mark Dickinson99d652e2009-12-30 12:12:23 +0000396- Issue #7534: Fix handling of IEEE specials (infinities, nans,
397 negative zero) in ** operator. The behaviour now conforms to that
398 described in C99 Annex F.
399
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000400- Issue #7579: the msvcrt module now has docstrings for all its functions.
401
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000402- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
403 used to drop the time part of the result.
404
Mark Dickinson46572832009-12-27 14:55:57 +0000405- Issue #1811: improve accuracy and cross-platform consistency for
406 true division of integers: the result of a/b is now correctly
407 rounded for ints a and b (at least on IEEE 754 platforms), and in
408 particular does not depend on the internal representation of a long.
409
Ezio Melottif84caf42009-12-24 22:25:17 +0000410- Issue #6108: unicode(exception) and str(exception) should return the same
411 message when only __str__ (and not __unicode__) is overridden in the subclass.
412
Ronald Oussoren92919a62009-12-24 13:30:58 +0000413- Issue #6834: replace the implementation for the 'python' and 'pythonw'
414 executables on OSX.
415
416 These executables now work properly with the arch(1) command:
417 ``arch -ppc python`` will start a universal binary version of python
418 in PPC mode (unlike previous releases).
419
R. David Murray0a0a1a82009-12-14 16:28:26 +0000420- Issue #1680159: unicode coercion during an 'in' operation no longer masks
421 the underlying error when the coercion fails for the left hand operand.

424
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000425- Issue #7466: segmentation fault when the garbage collector is called

476
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000477- Issue #7349: Make methods of file objects in the io module accept None as an
478 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
479 the same as passing no argument.
480
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000481- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

506 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
507 arguments for integer format codes (other than 'L'): previously an

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000555- Issue #7419: setlocale() could crash the interpreter on Windows when called
556 with invalid values.
557
Eric Smithc4ab8332009-11-29 17:40:57 +0000558- Issue #3382: 'F' formatting for float and complex now convert the
559 result to upper case. This only affects 'inf' and 'nan', since 'f'
560 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000561
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000562- Remove switch from "%f" formatting to "%g" formatting for floats
563 larger than 1e50 in absolute value.
564
Mark Dickinson18cfada2009-11-23 18:46:41 +0000565- Remove restrictions on precision when formatting floats. E.g.,
566 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
567 requested 120 significant digits instead.
568
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000569- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000573- Issue #7085: Fix crash when importing some extensions in a thread
574 on MacOSX 10.6.
575
Mark Dickinsonb678de82009-11-19 18:41:49 +0000576- Issue #7117: repr(x) for a float x returns a result based on the
577 shortest decimal string that's guaranteed to round back to x under
578 correct rounding (with round-half-to-even rounding mode).
579 Previously it gave a string based on rounding x to 17 decimal digits.
580 repr(x) for a complex number behaves similarly. On platforms where
581 the correctly-rounded strtod and dtoa code is not supported (see below),
582 repr is unchanged.
583
584- Issue #7117: On almost all platforms: float-to-string and
585 string-to-float conversions within Python are now correctly rounded.
586 Places these conversions occur include: str for floats and complex
587 numbers; the float and complex constructors; old-style and new-style
588 numeric formatting; serialization and deserialization of floats and
589 complex numbers using marshal, pickle and json; parsing of float and
590 imaginary literals in Python code; Decimal-to-float conversion.
591
592 The conversions use a Python-adapted version of David Gay's
593 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
594 functions. This code is supported on Windows, and on Unix-like
595 platforms using gcc, icc or suncc as the C compiler. There may be a
596 small number of platforms on which correct operation of this code
597 cannot be guaranteed, so the code is not used: notably, this applies
598 to platforms where the C double format is not IEEE 754 binary64, and
599 to platforms on x86 hardware where the x87 FPU is set to 64-bit
600 precision and Python's configure script is unable to determine how
601 to change the FPU precision. On these platforms conversions use the
602 platform strtod and dtoa, as before.
603
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000604- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000605 now uses the correctly-rounded string <-> float conversions
606 described above (when available), and so produces correctly rounded
607 results that will display nicely under the float repr. There are
608 two related small changes: (1) round now accepts any class with an
609 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000610 floats for the second argument), and (2) an excessively large second
611 integer argument (e.g., round(1.234, 10**100)) no longer raises an
612 exception.
613
Philip Jenveyfab8be22009-11-17 02:42:26 +0000614- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
615

Eric Smitha985a3a2009-05-05 18:26:08 +0000760- Issue #5920: For float.__format__, change the behavior with the
761 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
762 to be like 'g' but with at least one decimal point and with a
763 default precision of 12. Previously, the behavior the same but with
764 a default precision of 6. This more closely matches str(), and
765 reduces surprises when adding alignment flags to the empty
766 presentation type. This also affects the new complex.__format__ in
767 the same way.

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

907
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000908- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
909
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000910- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
911 an existing .py counterpart, override the co_filename attributes of all
912 code objects if the original filename is obsolete (which can happen if the
913 file has been renamed, moved, or if it is accessed through different paths).
914 Patch by Ziga Seilnacht and Jean-Paul Calderone.
915
Martin v. Löwis5344c992009-01-02 20:32:55 +0000916- Issue #4075: Use OutputDebugStringW in Py_FatalError.
917
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000918- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
919 file with `str' filename on Windows.
920
Antoine Pitrouaa687902009-01-01 14:11:22 +0000921- Issue #3680: Reference cycles created through a dict, set or deque iterator
922 did not get collected.
923
Nick Coghlan180e4002008-12-30 01:18:48 +0000924- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
925 where the tp_hash and tp_dict slots are both NULL.
926
Benjamin Peterson7af65562008-12-29 17:56:58 +0000927- Issue #4764: With io.open, IOError.filename is set when trying to open a
928 directory on POSIX systems.
929
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000930- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
931 systems.
932
Georg Brandl6425a2f2008-12-28 11:54:53 +0000933- Issue #4759: None is now allowed as the first argument of
934 bytearray.translate(). It was always allowed for bytes.translate().
935
Skip Montanarof205c132008-12-23 03:30:15 +0000936- Added test case to ensure attempts to read from a file opened for writing
937 fail.
938
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000939- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
940 print elapsed times, not only when some objects are uncollectable /
941 unreachable. Original patch by Neil Schemenauer.
942
Mark Dickinson1a707982008-12-17 16:14:37 +0000943- Issue #3439: Add a bit_length method to int and long.
944

946 Original patch by Neal Norwitz.
947
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000948- Issue #4597: Fixed exception handling when the __exit__ function of a
949 context manager returns a value that cannot be converted to a bool.
950
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000951- Issue #4597: Fixed several opcodes that weren't always propagating
952 exceptions.
953
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000954- Issue #4445: Replace "sizeof(PyStringObject)" with
955 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
956 str instances. On a typical machine this saves 3 bytes of memory
957 (on average) per string allocation.
958
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000959- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
960 interpreter to abort ("Fatal Python error: Could not reset the stack!")
961 instead of throwing a MemoryError.
962
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000963- Issue #3689: The list reversed iterator now supports __length_hint__
964 instead of __len__. Behavior now matches other reversed iterators.
965
Benjamin Petersonc078f922008-11-21 22:27:24 +0000966- Issue #4367: Python would segfault during compiling when the unicodedata
967 module couldn't be imported and \N escapes were present.
968
Vinay Sajip213faca2008-12-03 23:22:58 +0000969- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000970 method on file objects with closefd=False. The file descriptor is still
971 kept open but the file object behaves like a closed file. The ``FileIO``
972 object also got a new readonly attribute ``closefd``.
973
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000974- Issue #4348: Some bytearray methods returned that didn't cause any change to
975 the bytearray, returned the same bytearray instead of a copy.
976
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000977- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
978
Benjamin Peterson273c2332008-11-17 22:39:09 +0000979- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
980
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000981- Issue #4048: The parser module now correctly validates relative imports.
982
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000983- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
984 exec statement.
985
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000986- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
987 method does not return iterators for the 4th and 5th items.
988
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000989- Issue #4209: Enabling unicode_literals and the print_function in the same
990 __future__ import didn't work.
991
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000992- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000993 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000994
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000995- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
996 returned a path longer than MAX_PATH. (But It's doubtful this code path is
997 really executed because I cannot move to such directory on win2k)
998
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000999- Issue #4069: When set.remove(element) is used with a set element, the element
1000 is temporarily replaced with an equivalent frozenset. But the eventual
1001 KeyError would always report the empty frozenset([]) as the missing key. Now
1002 it correctly refers to the initial element.
1003
Antoine Pitrouae5bece2008-12-06 21:29:24 +00001004- Issue #4509: Various issues surrounding resize of bytearray objects to
1005 which there are buffer exports.
1006
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00001007- Issue #4748: Lambda generators no longer return a value.
1008
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00001009- Issue #3582: Use native TLS functions on Windows
1010
Gregory P. Smithae91d092009-03-02 05:13:57 +00001011- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
1012
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00001013- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
1014 short file names.
1015
Matthias Klose91a3b9e2009-04-05 21:19:13 +00001016- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1017 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00001018
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001019- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1020 returned them on 64bit platforms.
1021
Walter Dörwalded960ac2009-05-03 22:36:33 +00001022- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1023 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1024 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1025 of using the replace error handler in PyUnicode_DecodeUTF8().
1026
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001027- Issue #3739: The unicode-internal encoder now reports the number of characters
1028 consumed like any other encoder (instead of the number of bytes).
1029
Benjamin Peterson91c12eb2009-12-03 02:52:39 +00001030- Issue #2422: When compiled with the ``--with-valgrind`` option, the
1031 pymalloc allocator will be automatically disabled when running under
1032 Valgrind. This gives improved memory leak detection when running
1033 under Valgrind, while taking advantage of pymalloc at other times.

1053
Antoine Pitrou30b3b352009-12-02 20:37:54 +00001054- Issue #7333: The `posix` module gains an `initgroups()` function providing

1056 it. Patch by Jean-Paul Calderone.
1057
Tarek Ziadéa5076a22009-11-29 22:20:30 +00001058- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
1059 ownership when the group is not forced, because the group may be different
1060 from the user's group and inherit from its container when the test is run.
1061

1101
Nick Coghlan49868cb2009-11-15 07:30:34 +00001102- Issue #6816: runpy now provides a run_path function that allows Python code
1103 to execute file paths that refer to source or compiled Python files as well
1104 as zipfiles, directories and other valid sys.path entries that contain a
1105 __main__.py file. This allows applications that run other Python scripts to
1106 support the same flexibility as the CPython command line itself.

2218 ,'*i', '*l', and an x with a __long__ method could be packed by
2219 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
2220 TypeError used to be raised (with a confusing error message) for
2221 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

Mark Dickinson154b7ad2010-03-07 16:24:45 +00002223 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7
2224 beta 1, any argument with an __int__ method can be packed, but use
2225 of this feature triggers a DeprecationWarning.

Antoine Pitrouc98efe02009-11-06 22:34:35 +00002270- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
2271 primitives such as Lock, RLock, Condition, Event and Semaphore.
2272
Antoine Pitrou59c44f32009-10-30 17:07:08 +00002273- Issue #7222: Make thread "reaping" more reliable so that reference
2274 leak-chasing test runs give sensible results. The previous method of
2275 reaping threads could return successfully while some Thread objects were
2276 still referenced. This also introduces a new private function:
2277 :func:`thread._count()`.
2278
R. David Murray282396f2009-10-18 21:12:37 +00002279- Issue #7151: fixed regrtest -j so that output to stderr from a test no

2281
Antoine Pitrou58d2f262009-10-10 20:52:11 +00002282- Issue #7055: test___all__ now greedily detects all modules which have an
2283 __all__ attribute, rather than using a hardcoded and incomplete list.
2284
R. David Murray14dcd432009-10-14 13:58:07 +00002285- Issue #7058: Added save/restore for things like sys.argv and cwd to
2286 runtest_inner in regrtest, with warnings if the called test modifies them,
2287 and a new section in the summary report at the end.
R. David Murrayabe3d3e2009-10-05 17:03:09 +00002288

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002294- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2295 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2296 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2297 skip the tests if DISPLAY is defined but can't be used.
2298
Antoine Pitrou4698d992009-05-31 14:20:14 +00002299- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running

2303 it easy to import both normal and optimised versions of modules.
2304 test_heapq and test_warnings have been adjusted to use it, tests for
2305 other modules with both C and Python implementations in the stdlib
2306 can be adjusted to use it over time.
2307
Brett Cannonce3d2212009-04-01 20:25:48 +00002308- Fix test_warnings to no longer reset the warnings filter.

2313
R. David Murray41448c52009-03-31 19:57:24 +00002314- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00002315 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00002316 from test support, which does the conversion.
2317
Guilherme Polob1a98de2009-01-28 20:03:26 +00002318- Issue #5083: New 'gui' resource for regrtest.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002417- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2418
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002419- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2420 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2421 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2422 ``printf`` function, whereas PyString_FromFormat has an independent
2423 implementation and uses "%zd" on all platforms for size_t values.
2424 This makes a difference on win64, where ``printf`` needs "%Id" to display
2425 64bit values.
2426
Benjamin Peterson97179b02008-09-09 20:55:01 +00002427- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2431 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002435- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002441 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002442 was correctly parsed but parsing of subsequent arguments failed.
2443
Vinay Sajip35e3b032008-09-01 14:33:59 +00002444- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002445 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2446 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2447 when given a tuple of classes as second argument, were looking up
2448 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2449 type object.

Neal Norwitz18aa3882008-08-24 05:04:52 +00002451- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002588What's New in Python 2.6 beta 3?
2589================================
2590
Barry Warsaw07a4a382008-08-21 01:15:08 +00002591*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002592
2593Core and Builtins
2594-----------------
2595
Guido van Rossumf8402962008-08-20 15:01:50 +00002596- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2597 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2598 extensions do not automatically benefit from the class attribute
2599 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2600 to their tp_flags field if they care. This is a backwards
2601 compatibility feature; in 3.0, all types will use the cache by
2602 default.
2603
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002604- Keyword arguments can now follow starred arguments. (``f(a, *args,
2605 keyword=23)`` is now valid syntax.)
2606
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002607- ctypes function pointers that are COM methods have a boolean True
2608 value again.
2609
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002610- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2611 by denying s# to parse objects that have a releasebuffer procedure,
2612 and introducing s*.
2613
Georg Brandl1e13ea92008-08-11 09:07:59 +00002614- Issue #3537: Fix an assertion failure when an empty but presized dict
2615 object was stored in the freelist.
2616
Mark Dickinsonb6467572008-08-04 21:30:09 +00002617- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2618 ValueError consistently across platforms.
2619
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002620- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2621 (64bit Unix, for example), unichr() would truncate its argument and return
2622 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2623
Neal Norwitze7d8be82008-07-31 17:17:14 +00002624- Apply security patches from Apple.
2625
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002626- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2627 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2628
Antoine Pitrou92f82162008-07-25 22:22:08 +00002629- Issue #1819: function calls with several named parameters are now on
2630 average 35% faster (as measured by pybench).
2631
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002632- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2633 the python debugger steps into a class statement: the free variables (local
2634 variables defined in an outer scope) would be deleted from the outer scope.
2635
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002636- Issue #2620: Overflow checking when allocating or reallocating memory
2637 was not always being done properly in some python types and extension
2638 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2639 all been updated to perform better checks and places in the code that
2640 would previously leak memory on the error path when such an allocation
2641 failed have been fixed.
2642
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002643Library
2644-------
2645
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002646- Issue #3612: Added some missing basic types in ctypes.wintypes.
2647
Benjamin Petersone977ad42008-08-20 01:42:01 +00002648- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2649 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2650
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002651- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2652 version reported by these tools does not necessarily follow the python
2653 version numbering scheme, so the module is less strict when parsing it.
2654
Nick Coghlanf70385a2008-08-18 12:42:46 +00002655- Issue #2235: Added Py3k warnings for types which will become unhashable
2656 under the stricter __hash__ inheritance rules in 3.0. Several types
2657 which did not meet the rules for hash invariants and were already
2658 unhashable in 3.0 have now been explicitly flagged as unhashable in
2659 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2660 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2661
Brett Cannon88f801d2008-08-18 00:46:22 +00002662- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2663 imported into the module but exposed as part of the module's API.
2664
Brett Cannon7b96f072008-08-18 00:41:11 +00002665- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2666
Brett Cannon46225e72008-08-18 00:36:52 +00002667- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2668
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002669- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2670
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002671- Issue #3575: Incremental decoder's decode function now takes bytearray
2672 by using 's*' instead of 't#'.
2673
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002674- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002675 fails unicode conversion on 2nd parameter. (windows only)
2676
Facundo Batista94f243a2008-08-17 03:38:39 +00002677- Issue 2464. urllib2 now supports a malformation in the URL received
2678 in a redirect.
2679
Brett Cannonabe423e2008-08-16 21:47:07 +00002680- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002681 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002682
Facundo Batistaeb90b782008-08-16 14:44:07 +00002683- Issue #2776: fixed small issue when handling an URL with double slash
2684 after a 302 response in the case of not going through a proxy.
2685
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002686- Issue #2676: in the email package, content-type parsing was hanging on
2687 pathological input because of quadratic or exponential behaviour of a
2688 regular expression.
2689
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002690- Issue #3476: binary buffered reading through the new "io" library is now
2691 thread-safe.
2692
Brett Cannonbf3157b2008-08-14 05:00:03 +00002693- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2694 since mimetools itself is deprecated. Because modules are cached, all
2695 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2696
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002697- Issue #3134: shutil referenced undefined WindowsError symbol.
2698
Robert Schuppenies14646332008-08-10 11:01:53 +00002699- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2700 menu entries were not deleted.
2701
Brett Cannon83e81842008-08-09 23:30:55 +00002702- Copied the implementation of reduce() to _functools.reduce() to have a
2703 version that did not raise a DeprecationWarning under -3.
2704
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002705- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2706 a MemoryError rather than silently stop the iteration.
2707
Guido van Rossum59ce9012008-08-09 14:55:34 +00002708- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2709 to _sre.compile() will now be rejected. This should not affect anybody
2710 since the re.compile() function never generates invalid re-bytecode.
2711
Skip Montanaroa032bf42008-08-08 22:52:51 +00002712- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2713 upon first access it can be automatically initialized from the csv file if
2714 it wasn't initialized during instantiation.
2715
Brett Cannon3aa2a492008-08-06 22:28:09 +00002716- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2717 the reload() built-in has been removed.
2718
Brett Cannon7e30b672008-08-04 21:52:25 +00002719- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002720 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2728 raised an AttributeError.
2729
Benjamin Peterson01a24322008-07-28 23:35:27 +00002730- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002731 asking for a specific length. This problem only affected files opened
2732 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002733
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002734- Issue #3449: Update decimal module to use most recent specification
2735 (v. 1.68) and tests (v. 2.58) from IBM.
2736
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002737- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2745
2746- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2747 invalid arguments.
2748
2749- Issue #3302: Fix several crashes when calling locale's gettext functions
2750 with None arguments.
2751
2752- Issue #3389: Allow resolving dotted names for handlers in logging
2753 configuration files.
2754
2755- Deprecate the sunaudio module for removal in Python 3.0.
2756
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002757- Issue #3394: zipfile.writestr sets external attributes when passed a
2758 file name rather than a ZipInfo instance, so files are extracted with
2759 mode 0600 rather than 000 under Unix.
2760
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002761- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2762 argument in python 2.5, this broke code that subclassed Popen to include its
2763 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002773- Issue #2235: the C API function PyObject_HashNotImplemented and its
2774 interaction with the tp_hash slot (added in 2.6b2) are now documented
2775
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002776- Issue #643841: The language reference now provides more detailed
2777 coverage of the lookup process for special methods. The disclaimers
2778 regarding lack of coverage of new-style classes have also been
2779 removed, since the coverage is now fairly reasonable.

2788-----------------
2789
Georg Brandl3e483f62008-07-16 22:57:41 +00002790- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2791 its methods now allow for items objects that can be converted to
2792 an integer using operator.index().
2793
Mark Dickinson64b7e502008-07-16 09:40:03 +00002794- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2795 produced a ValueError instead of giving the correct float.
2796
Eric Smitha5fa5a22008-07-16 00:11:49 +00002797- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2798 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2799
Mark Dickinson7103aa42008-07-15 19:08:33 +00002800- Issue #3008: the float type has a new instance method 'float.hex'
2801 and a new class method 'float.fromhex' to convert floating-point
2802 numbers to and from hexadecimal strings, respectively.
2803
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002804- Issue #2235: __hash__ is once again inherited by default. To allow
2805 collections.Hashable to remain meaningful in the presence of the
2806 default hash implementation (object.__hash__), it is now possible
2807 to explicit block inheritance of hash by setting __hash__=None at
2808 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2809 level.
2810
Nick Coghlanb028f502008-07-13 14:52:36 +00002811- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2812 the parent module cannot be found while performing an absolute import.
2813 This means that an incorrectly defined __package__ attribute will
2814 now only prevent relative imports in that module rather than causing
2815 all imports from that module to fail.
2816
Nick Coghlan14ff9942008-07-08 14:21:42 +00002817- Issue #2517: Allow unicode messages in Exceptions again by correctly
2818 bypassing the instance dictionary when looking up __unicode__ on
2819 new-style classes.
2820
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002821- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2822 set to a custom object whose write() method happens to install
2823 another file in sys.stdout.

2827 another thread's dictionary.
2828
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002829- Issue #3004: Minor change to slice.indices(): the start and stop
2830 arguments are now treated identically, making the behaviour easier
2831 to describe and understand. For example, slice(None, -10,
2832 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2833 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2834 10, -1).
2835
Georg Brandl278fc502008-07-19 12:46:12 +00002836- Issue #3219: Calling a function with repeated keyword arguments,
2837 f(a=2, a=23), would not cause a syntax error. This was a regression
2838 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00003288 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003289
3290 This is controlled by the configure argument ``--with-universal-archs``:
3291
3292 - ``--with-universal-archs=all``: install 4-way universal
3293
3294 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3295
3296 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3297
3298 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003350- Issue #1631171: Re-implement the 'warnings' module in C (the
3351 original Python code has been kept as backup). This will allow for
3352 using the 'warning's machinery in such places as the parser where
3353 use of pure Python code is not possible. Both the ``showarning()``
3354 and ``formatwarning()`` gain an optional 'line' argument which is
3355 not called by default for backwards-compatibility reasons. Setting
3356 ``warnings.showwarning()`` to an implementation that lacks support
3357 for the ``line`` argument will raise a DeprecationWarning.

3381
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003382- The getpass module has been improved on Unix. It now uses /dev/tty
3383 by default and uses stderr instead of stdout. A GetPassWarning is
3384 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003412- Issue #2385: distutils.core.run_script() makes __file__ available,
3413 so the controlled environment will more closely mirror the typical
3414 script environment. This supports setup.py scripts that refer to
3415 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003420- Issue #2550: The approach used by client/server code for obtaining
3421 ports to listen on in network-oriented tests has been refined in an
3422 effort to facilitate running multiple instances of the entire
3423 regression test suite in parallel without issue.
3424 test_support.bind_port() has been fixed such that it will always
3425 return a unique port -- which wasn't always the case with the
3426 previous implementation, especially if socket options had been set
3427 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3428 new implementation of bind_port() will actually raise an exception
3429 if it is passed an AF_INET/SOCK_STREAM socket with either the
3430 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3431 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3432 the socket it's been passed. This currently only applies to
3433 Windows. This option prevents any other sockets from binding to the
3434 host/port we've bound to, thus removing the possibility of the
3435 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3436 when a second SOCK_STREAM socket binds and accepts to a host/port
3437 that's already been bound by another socket. The optional preferred
3438 port parameter to bind_port() has been removed. Under no
3439 circumstances should tests be hard coding ports!
3440
3441 test_support.find_unused_port() has also been introduced, which will
3442 pass a temporary socket object to bind_port() in order to obtain an
3443 unused port. The temporary socket object is then closed and
3444 deleted, and the port is returned. This method should only be used
3445 for obtaining an unused port in order to pass to an external program
3446 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3447 a parameter to a server-oriented class that doesn't give you direct
3448 access to the underlying socket used.
3449
3450 Finally, test_support.HOST has been introduced, which should be used
3451 for the host argument of any relevant socket calls (i.e. bind and
3452 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003453
3454 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003455 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003456 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3457 test_asynchat and test_socket_ssl.
3458
Georg Brandl3ee81df2008-05-17 18:14:43 +00003459 It is now possible for multiple instances of the regression test
3460 suite to run in parallel without issue.

3726Core and builtins
3727-----------------
3728
Fred Drakea8ee94b2008-03-01 02:45:07 +00003729- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003730 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003731
Georg Brandlad61bc82008-02-23 15:11:18 +00003732- Issue #2067: file.__exit__() now calls subclasses' close() method.
3733
3734- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003735
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003736- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003737 issue 215555 for a discussion.
3738
Eric Smitha73fbe72008-02-23 03:09:44 +00003739- Added the future_builtins module, which contains hex() and oct().
3740 These are the PEP 3127 version of these functions, designed to be
3741 compatible with the hex() and oct() builtins from Python 3.0. They
3742 differ slightly in their output formats from the existing, unchanged
3743 Python 2.6 builtins. The expected usage of the future_builtins
3744 module is:
3745 from future_builtins import hex, oct
3746
Eric Smith7ef40bf2008-02-20 23:34:22 +00003747- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3748 exponents for exponents with absolute value < 100. Follows C99
3749 standard. This is a change on Windows, which would use 3 digits.
3750 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3751 so that any alterations it does to the resulting string will be
3752 available in stringlib/formatter.h (for float.__format__).
3753
Eric Smith5a3c1352008-02-19 13:21:56 +00003754- Implemented PEP 3101, Advanced String Formatting. This adds a new
3755 builtin format(); a format() method for str and unicode; a
3756 __format__() method to object, str, unicode, int, long, float, and
3757 datetime; the class string.Formatter; and the C API
3758 PyObject_Format().
3759
Georg Brandl3ee81df2008-05-17 18:14:43 +00003760- Fixed several potential crashes, all caused by specially crafted
3761 __del__ methods exploiting objects in temporarily inconsistent
3762 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003763
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003764- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003765 prevent a possible crash: an Abstract Base Class would try to access
3766 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003767
Georg Brandl3ee81df2008-05-17 18:14:43 +00003768- Fixed repr() and str() of complex numbers with infinity or nan as
3769 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003770
Georg Brandl3ee81df2008-05-17 18:14:43 +00003771- Clear all free lists during a gc.collect() of the highest generation
3772 in order to allow pymalloc to free more arenas. Python may give back
3773 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003774
Georg Brandl3ee81df2008-05-17 18:14:43 +00003775- Issue #2045: Fix an infinite recursion triggered when printing a
3776 subclass of collections.defaultdict, if its default_factory is set
3777 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003778
Christian Heimesf75dbef2008-02-08 00:11:31 +00003779- Fixed a minor memory leak in dictobject.c. The content of the free
3780 list was not freed on interpreter shutdown.
3781
Georg Brandl21e99f42010-03-07 15:23:59 +00003782- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003783 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003784
Georg Brandl3ee81df2008-05-17 18:14:43 +00003785- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3786 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003787 to compact the internal free lists of pre-allocted ints and floats.
3788
Georg Brandl3ee81df2008-05-17 18:14:43 +00003789- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3790 calls. Python expected the return type int but the fork familie
3791 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003792
Georg Brandl3ee81df2008-05-17 18:14:43 +00003793- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3794 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003795
Georg Brandl3ee81df2008-05-17 18:14:43 +00003796- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3797 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003798

Georg Brandl3ee81df2008-05-17 18:14:43 +00003802- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3803 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003804
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805- Patch #1473257: generator objects gain a gi_code attribute. This is
3806 the same object as the func_code attribute of the function that
3807 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003808
Georg Brandl3ee81df2008-05-17 18:14:43 +00003809- Issue #1920: "while 0" statements were completely removed by the
3810 compiler, even in the presence of an "else" clause, which is
3811 supposed to be run when the condition is false. Now the compiler
3812 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003813
Guido van Rossumeead05f2008-01-24 18:21:02 +00003814- A few crashers fixed: weakref_in_del.py (issue #1377858);
3815 loosing_dict_ref.py (issue #1303614, test67.py);
3816 borrowed_ref_[34].py (not in tracker).
3817
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003818- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003819 suppressed while an extension is loaded by calling SetErrorMode in
3820 dynload_win.c. The error is still reported properly.
3821
Georg Brandl3ee81df2008-05-17 18:14:43 +00003822- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003823 several extension methods and modules do not work without unicode
3824 support.
3825
Georg Brandl26543b12008-01-21 18:36:51 +00003826- Issue #1882: when compiling code from a string, encoding cookies in the
3827 second line of code were not always recognized correctly.
3828
Georg Brandl14404b62008-01-19 19:27:05 +00003829- Issue #1679: "0x" was taken as a valid integer literal.
3830
Georg Brandl6caad7d2008-01-26 14:19:22 +00003831- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003832 added.
3833
Christian Heimesc94e2b52008-01-14 04:13:37 +00003834- sys.float_info / PyFloat_GetInfo: The floating point information
3835 object was converted from a dict to a specialized structseq object.
3836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- Patch #1816: Added sys.flags structseq. It exposes the status of
3838 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003839
Georg Brandl3ee81df2008-05-17 18:14:43 +00003840- Objects/structseq.c: Implemented new structseq representation. The
3841 patch makes structseqs (e.g. the return value of os.stat) more
3842 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003843
Georg Brandl3ee81df2008-05-17 18:14:43 +00003844- Patch #1700288: added a type attribute cache that caches method

3853 envvar and sys.dont_write_bytecode attribute. All these can be set
3854 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003855
Georg Brandl3ee81df2008-05-17 18:14:43 +00003856- Improve some exception messages when Windows fails to load an
3857 extension module. Now we get for example '%1 is not a valid Win32
3858 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003866 and INF. float("nan"), float("inf") and float("-inf") now work on
3867 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003868
Georg Brandl3ee81df2008-05-17 18:14:43 +00003869- Compiler now generates simpler and faster code for dictionary
3870 literals. The oparg for BUILD_MAP now indicates an estimated
3871 dictionary size. There is a new opcode, STORE_MAP, for adding
3872 entries to the dictionary.

Neal Norwitz44f326e2007-10-05 05:29:17 +00003914- Fix warnings found by the new version of the Coverity checker.
3915
Georg Brandl21e99f42010-03-07 15:23:59 +00003916- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003917 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3918 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003919
Georg Brandl3ee81df2008-05-17 18:14:43 +00003920- Issue #1686386: Tuple's tp_repr did not take into account the
3921 possibility of having a self-referential tuple, which is possible
3922 from C code. Nor did object's tp_str consider that a type's tp_str
3923 could do something that could lead to an inifinite recursion.
3924 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3925 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003926
Georg Brandl3ee81df2008-05-17 18:14:43 +00003927- Issue #1164: It was possible to trigger deadlock when using the
3928 'print' statement to write to a file since the GIL was not released
3929 as needed. Now PyObject_Print() does the right thing along with
3930 various tp_print implementations of the built-in types and those in
3931 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003932
Georg Brandl3ee81df2008-05-17 18:14:43 +00003933- Issue #1147: Exceptions were directly allowing string exceptions in
3934 their throw() method even though string exceptions no longer
3935 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003936
Georg Brandl3ee81df2008-05-17 18:14:43 +00003937- Issue #1096: Prevent a segfault from getting the repr of a very
3938 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003939
Brett Cannon1e534b52007-09-07 04:18:30 +00003940- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003941 PyObject_Call() never calling back out to Python code to trigger
3942 recursion depth updates/checks. Required the creation of a static
3943 RuntimeError instance in case normalizing an exception put the
3944 recursion check value past its limit. Fixes crashers
3945 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003946
Georg Brandl3ee81df2008-05-17 18:14:43 +00003947- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003960- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003961 __*__ attributes. (Some already existed, e.g., __doc__ and
3962 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003963
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003964- Add -3 option to the interpreter to warn about features that are
3965 deprecated and will be changed/removed in Python 3.0.
3966
Georg Brandl2134e752007-05-21 20:34:16 +00003967- Patch #1686487: you can now pass any mapping after '**' in function
3968 calls.
3969
Collin Winter62903052007-05-18 23:11:24 +00003970- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003971 "except E as target:". This is to provide forwards compatibility
3972 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003973
Brett Cannon229cee22007-05-05 01:34:02 +00003974- Deprecate BaseException.message as per PEP 352.
3975
Georg Brandl3ee81df2008-05-17 18:14:43 +00003976- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00003977 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003978
Vinay Sajip8549ce32007-05-06 17:53:37 +00003979- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003980 setting a plain string, ie don't expand to single letter identifiers.
3981
Raymond Hettinger13936692007-04-11 18:40:58 +00003982- Request #1191699: Slices can now be pickled.
3983
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003984- Request #1193128: str.translate() now allows a None argument for
3985 translations that only remove characters without re-mapping the
3986 remaining characters.
3987
Georg Brandl5cb76c12007-03-21 09:00:39 +00003988- Patch #1682205: a TypeError while unpacking an iterable is no longer

3990
Neal Norwitzaa754b72007-03-21 06:39:48 +00003991- Remove unused file Python/fmod.c.
3992
Guido van Rossum143b5642007-03-23 04:58:42 +00003993- Bug #1683368: The object.__init__() and object.__new__() methods are
3994 now stricter in rejecting excess arguments. The only time when
3995 either allows excess arguments is when it is not overridden and the
3996 other one is. For backwards compatibility, when both are
3997 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003998 warning later). Also, type.__init__() insists on the same signature
3999 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004000
Georg Brandl3ee81df2008-05-17 18:14:43 +00004001- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4002 object to complex using its __complex__() method before falling back
4003 to the __float__() method. Therefore, the functions in the cmath
4004 module now can operate on objects that define a __complex__()
4005 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004006
Georg Brandl3ee81df2008-05-17 18:14:43 +00004007- Patch #1623563: allow __class__ assignment for classes with
4008 __slots__. The old and the new class are still required to have the
4009 same slot names.

4015 ``object.__reduce_ex__()`` is called with an object that is faking
4016 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004017
Georg Brandl3ee81df2008-05-17 18:14:43 +00004018- Patch #1680015: Don't modify __slots__ tuple if it contains an

4022
Georg Brandl7b9c5552007-03-12 14:30:05 +00004023- Bug #1678647: write a newline after printing an exception in any
4024 case, even when converting the value to a string failed.
4025
Georg Brandl871f1bc2007-03-12 13:17:36 +00004026- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004027 its argument, if it exists. If not, it will work like before. This
4028 allows customizing the output of dir() in the presence of a
4029 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004037- Patch #1491866: change the complex() constructor to allow
4038 parthensized forms. This means complex(repr(x)) now works instead of
4039 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004040
Georg Brandlaa2321b2007-03-07 00:40:28 +00004041- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004042 makes the filenames the warning module prints much more sensible
4043 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004044
Georg Brandl49aafc92007-03-07 00:34:46 +00004045- Variant of patch #697613: don't exit the interpreter on a SystemExit
4046 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004047 variable is given, but break into the interactive interpreter just
4048 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004056- Patch #1674228: when assigning a slice (old-style), check for the
4057 sq_ass_slice instead of the sq_slice slot.
4058
Georg Brandl3ee81df2008-05-17 18:14:43 +00004059- When printing an unraisable error, don't print exceptions. before
4060 the name. This duplicates the behavior whening normally printing
4061 exceptions.

4690 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004971- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4972 with RFC 3207 and forgets any knowledge obtained from the server not
4973 obtained from the TLS negotiation itself. Patch contributed by Bill
4974 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004975
Georg Brandl3ee81df2008-05-17 18:14:43 +00004976- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004977 that the SMTP.starttls() caller no longer needs to call ehlo()
4978 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004979 does not claim to support starttls. Adds the
4980 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4981 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005035- itertools.chain() now has an alternate constructor,

5061 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5062 silently miscode subclasses of those types. Now, it raises a
5063 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005064

Georg Brandl3ee81df2008-05-17 18:14:43 +00005079 time so that opening a database previously created with the DB_DUP
5080 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5081 opens. Specifically: dictionary assignment to a DB object will
5082 replace all values for a given key when the database allows
5083 duplicate values. DB users should use DB.put(k, v) when they want
5084 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005085

5091 characters with ASCII value less than 32. Also, it correctly quotes
5092 dots only if they occur on a single line, as opposed to the previous
5093 behavior of quoting dots if they are the second character of any
5094 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005095

5417-----
5418
Georg Brandl3ee81df2008-05-17 18:14:43 +00005419- Unified naming convention for free lists and their limits. All free
5420 lists in Object/ are named ``free_list``, the counter ``numfree``
5421 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5422 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005423
Georg Brandl3ee81df2008-05-17 18:14:43 +00005424- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5425 to ``PyTuple_SetItem``, it can be used to populate a brand new
5426 frozenset; but it does not steal a reference to the added item.

5435
5436- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5437 ``PyFloat_GetInfo()`` to the float API.
5438
Georg Brandl3ee81df2008-05-17 18:14:43 +00005439- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5440 of w# format code incorrectly truncated the length to an int, even
5441 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5442 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005443
Georg Brandl3ee81df2008-05-17 18:14:43 +00005444- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5445 Py_TYPE and Py_REFCNT.

5461
5462- Fix some leftovers from the conversion from int to Py_ssize_t
5463 (relevant to strings and sequences of more than 2**31 items).
5464
5465- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5466 outside of pystate.c and should not be necessary.
5467
Georg Brandl3ee81df2008-05-17 18:14:43 +00005468- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5469 absolute imports. In earlier versions they might have used relative
5470 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005471
Georg Brandl3ee81df2008-05-17 18:14:43 +00005472- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5473 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005474
Georg Brandl3ee81df2008-05-17 18:14:43 +00005475- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5483 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5484 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5485 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005486

Georg Brandl3ee81df2008-05-17 18:14:43 +00005500- Removed the macfs module. It had been deprecated since Python 2.5.
5501 This lead to the deprecation of macostools.touched() as it relied
5502 solely on macfs and was a no-op under OS X.
