Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000343What's New in Python 2.7 alpha 2?
344=================================
345
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000346*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000347
348Core and Builtins
349-----------------
350
Benjamin Petersonecdae192010-01-04 00:43:01 +0000351- The __complex__ method is now looked up on the class of instances to make it
352 consistent with other special methods.
353
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000354- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
355 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
356
Mark Dickinson1b34d252010-01-01 17:27:30 +0000357- Issue #5080: A number of functions and methods previously produced a
358 DeprecationWarning when passed a float argument where an integer was
359 expected. These functions and methods now raise TypeError instead.
360 The majority of the effects of this change are in the extension
361 modules, but some core functions and methods are affected: notably
362 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
363 methods.
364
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000365- Issue #7604: Deleting an unset slotted attribute did not raise an
366 AttributeError.
367
Mark Dickinson99d652e2009-12-30 12:12:23 +0000368- Issue #7534: Fix handling of IEEE specials (infinities, nans,
369 negative zero) in ** operator. The behaviour now conforms to that
370 described in C99 Annex F.
371
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000372- Issue #7579: the msvcrt module now has docstrings for all its functions.
373
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000374- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
375 used to drop the time part of the result.
376
Mark Dickinson46572832009-12-27 14:55:57 +0000377- Issue #1811: improve accuracy and cross-platform consistency for
378 true division of integers: the result of a/b is now correctly
379 rounded for ints a and b (at least on IEEE 754 platforms), and in
380 particular does not depend on the internal representation of a long.
381
Ezio Melottif84caf42009-12-24 22:25:17 +0000382- Issue #6108: unicode(exception) and str(exception) should return the same
383 message when only __str__ (and not __unicode__) is overridden in the subclass.
384
Ronald Oussoren92919a62009-12-24 13:30:58 +0000385- Issue #6834: replace the implementation for the 'python' and 'pythonw'
386 executables on OSX.
387
388 These executables now work properly with the arch(1) command:
389 ``arch -ppc python`` will start a universal binary version of python
390 in PPC mode (unlike previous releases).
391
R. David Murray0a0a1a82009-12-14 16:28:26 +0000392- Issue #1680159: unicode coercion during an 'in' operation no longer masks
393 the underlying error when the coercion fails for the left hand operand.
394
Benjamin Peterson4895af42009-12-13 16:36:53 +0000395- Issue #7491: Metaclass's __cmp__ method was ignored.
396
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000397- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +0000398 in the middle of populating a tuple. Patch by Florent Xicluna.

411 by Arfrever.
412
Antoine Pitrou80157252010-01-08 19:20:17 +0000413- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
414 renaming of `cPickle` to `pickle`. The warning was annoying since there's
415 no alternative to cPickle if you care about performance. Patch by Florent
416 Xicluna.
417

Antoine Pitrou673ddf92010-01-03 22:29:56 +0000424- Issue #7471: Improve the performance of GzipFile's buffering mechanism,
425 and make it implement the `io.BufferedIOBase` ABC to allow for further
426 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
427
428- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000429 parameter to allow specifying where your connections come from.
430

443 the Distutils upload command to avoid an error when PyPI reads it.
444 This occurs on long passwords. Initial patch by JP St. Pierre.
445
446- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000447 Patch by Tatsuhiro Tsujikawa.
448
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000449- Issue #7349: Make methods of file objects in the io module accept None as an
450 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
451 the same as passing no argument.
452
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000453- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
454 like other file objects.
455
Lars Gustäbel92ca7562009-12-13 11:32:27 +0000456- Issue #7357: tarfile no longer suppresses fatal extraction errors by
457 default.
458

Mark Dickinson1b34d252010-01-01 17:27:30 +0000476- Issue #5080: The argument parsing functions PyArg_ParseTuple,
477 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
478 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
479 arguments for integer format codes (other than 'L'): previously an
480 attempt to pass a float resulted in a DeprecationWarning; now it
481 gives a TypeError. For the 'L' format code (which previously had no
482 warning) there is now a DeprecationWarning.

526
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000527- Issue #7419: setlocale() could crash the interpreter on Windows when called
528 with invalid values.
529
Eric Smithc4ab8332009-11-29 17:40:57 +0000530- Issue #3382: 'F' formatting for float and complex now convert the
531 result to upper case. This only affects 'inf' and 'nan', since 'f'
532 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000533
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000534- Remove switch from "%f" formatting to "%g" formatting for floats
535 larger than 1e50 in absolute value.
536
Mark Dickinson18cfada2009-11-23 18:46:41 +0000537- Remove restrictions on precision when formatting floats. E.g.,
538 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
539 requested 120 significant digits instead.
540
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000541- Add Py3k warnings for parameter names in parenthesis.
542

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000545- Issue #7085: Fix crash when importing some extensions in a thread
546 on MacOSX 10.6.
547
Mark Dickinsonb678de82009-11-19 18:41:49 +0000548- Issue #7117: repr(x) for a float x returns a result based on the
549 shortest decimal string that's guaranteed to round back to x under
550 correct rounding (with round-half-to-even rounding mode).
551 Previously it gave a string based on rounding x to 17 decimal digits.
552 repr(x) for a complex number behaves similarly. On platforms where
553 the correctly-rounded strtod and dtoa code is not supported (see below),
554 repr is unchanged.
555
556- Issue #7117: On almost all platforms: float-to-string and
557 string-to-float conversions within Python are now correctly rounded.
558 Places these conversions occur include: str for floats and complex
559 numbers; the float and complex constructors; old-style and new-style
560 numeric formatting; serialization and deserialization of floats and
561 complex numbers using marshal, pickle and json; parsing of float and
562 imaginary literals in Python code; Decimal-to-float conversion.
563
564 The conversions use a Python-adapted version of David Gay's
565 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
566 functions. This code is supported on Windows, and on Unix-like
567 platforms using gcc, icc or suncc as the C compiler. There may be a
568 small number of platforms on which correct operation of this code
569 cannot be guaranteed, so the code is not used: notably, this applies
570 to platforms where the C double format is not IEEE 754 binary64, and
571 to platforms on x86 hardware where the x87 FPU is set to 64-bit
572 precision and Python's configure script is unable to determine how
573 to change the FPU precision. On these platforms conversions use the
574 platform strtod and dtoa, as before.
575
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000576- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000577 now uses the correctly-rounded string <-> float conversions
578 described above (when available), and so produces correctly rounded
579 results that will display nicely under the float repr. There are
580 two related small changes: (1) round now accepts any class with an
581 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000582 floats for the second argument), and (2) an excessively large second
583 integer argument (e.g., round(1.234, 10**100)) no longer raises an
584 exception.
585
Philip Jenveyfab8be22009-11-17 02:42:26 +0000586- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
587
Benjamin Petersone36199b2009-11-12 23:39:44 +0000588- Fix several issues with compile(). The input can now contain Windows and Mac

713 statement and correctly lookup the __enter__ and __exit__ special methods.
714
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000715- Issue #5829: complex("1e500") no longer raises OverflowError. This
716 makes it consistent with float("1e500") and interpretation of real
717 and imaginary literals.

725
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000726- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
727 (1) inf and nan strings with trailing whitespace were incorrectly
728 rejected; (2) parsing of strings representing infinities and nans
729 was locale aware; and (3) the interpretation of fromhex('-nan')
730 didn't match that of float('-nan').
731
Eric Smitha985a3a2009-05-05 18:26:08 +0000732- Issue #5920: For float.__format__, change the behavior with the
733 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
734 to be like 'g' but with at least one decimal point and with a
735 default precision of 12. Previously, the behavior the same but with
736 a default precision of 6. This more closely matches str(), and
737 reduces surprises when adding alignment flags to the empty
738 presentation type. This also affects the new complex.__format__ in
739 the same way.
740
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000741- Issue #5890: in subclasses of 'property' the __doc__ attribute was

Eric Smithaca19e62009-04-22 13:29:05 +0000768- Implement PEP 378, Format Specifier for Thousands Separator, for
769 floats, ints, and longs.
770
771- Issue #5515: 'n' formatting for ints, longs, and floats handles
772 leading zero formatting poorly.
773

781 some builtin types.
782
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000783- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000784 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000785
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000786- Issue #5759: float() didn't call __float__ on str subclasses.

804 untrackable objects are not tracked by the garbage collector. This can
805 reduce the size of collections and therefore the garbage collection overhead
806 on long-running programs, depending on their particular use of datatypes.
807
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000808- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
809 improve its performance. Long divisions and remainder operations
810 are now between 50% and 150% faster.
811
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000812- Issue #4258: Make it possible to use base 2**30 instead of base
813 2**15 for the internal representation of integers, for performance
814 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
815 --enable-big-digits option to configure, which overrides the
816 default. Add sys.long_info structseq to provide information about
817 the internal format.

828
Brett Cannon6c4cff02009-03-11 04:51:06 +0000829- Issue #3652: Make the 'line' argument for warnings.showwarning() a
830 requirement. Means the DeprecationWarning from Python 2.6 can go away.
831
Eric Smithe9fb6862009-02-20 14:02:36 +0000832- Issue #5247: Improve error message when unknown format codes are

840 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
841 on a 64-bit system.
842
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000843- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
844 rotating the object pointer by 4 bits to the right.

850
Georg Brandl29c6a282009-04-05 20:23:13 +0000851- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000852 were suppressing all exceptions. These include list(), filter(), map(),
853 zip(), and bytearray().
854

922
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000923- Issue #4597: Fixed several opcodes that weren't always propagating
924 exceptions.
925
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000926- Issue #4445: Replace "sizeof(PyStringObject)" with
927 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
928 str instances. On a typical machine this saves 3 bytes of memory
929 (on average) per string allocation.
930
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000931- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
932 interpreter to abort ("Fatal Python error: Could not reset the stack!")
933 instead of throwing a MemoryError.
934
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000935- Issue #3689: The list reversed iterator now supports __length_hint__

937
Benjamin Petersonc078f922008-11-21 22:27:24 +0000938- Issue #4367: Python would segfault during compiling when the unicodedata

940
Vinay Sajip213faca2008-12-03 23:22:58 +0000941- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000942 method on file objects with closefd=False. The file descriptor is still
943 kept open but the file object behaves like a closed file. The ``FileIO``
944 object also got a new readonly attribute ``closefd``.
945
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000946- Issue #4348: Some bytearray methods returned that didn't cause any change to
947 the bytearray, returned the same bytearray instead of a copy.
948
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000949- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
950

959 method does not return iterators for the 4th and 5th items.
960
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000961- Issue #4209: Enabling unicode_literals and the print_function in the same
962 __future__ import didn't work.
963
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000964- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000965 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000966
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000967- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
968 returned a path longer than MAX_PATH. (But It's doubtful this code path is
969 really executed because I cannot move to such directory on win2k)
970
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000971- Issue #4069: When set.remove(element) is used with a set element, the element
972 is temporarily replaced with an equivalent frozenset. But the eventual
973 KeyError would always report the empty frozenset([]) as the missing key. Now
974 it correctly refers to the initial element.
975
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000976- Issue #4509: Various issues surrounding resize of bytearray objects to

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000991- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
992 returned them on 64bit platforms.
993
Walter Dörwalded960ac2009-05-03 22:36:33 +0000994- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
995 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
996 step. This avoids problems with counting UTF-8 bytes that ignores the effect
997 of using the replace error handler in PyUnicode_DecodeUTF8().
998
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000999- Issue #3739: The unicode-internal encoder now reports the number of characters
1000 consumed like any other encoder (instead of the number of bytes).
1001
Benjamin Peterson91c12eb2009-12-03 02:52:39 +00001002- Issue #2422: When compiled with the ``--with-valgrind`` option, the
1003 pymalloc allocator will be automatically disabled when running under
1004 Valgrind. This gives improved memory leak detection when running
1005 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00001074- Issue #6816: runpy now provides a run_path function that allows Python code

2272 test_heapq and test_warnings have been adjusted to use it, tests for
2273 other modules with both C and Python implementations in the stdlib
2274 can be adjusted to use it over time.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002385- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2386
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002387- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2388 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2389 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2390 ``printf`` function, whereas PyString_FromFormat has an independent
2391 implementation and uses "%zd" on all platforms for size_t values.
2392 This makes a difference on win64, where ``printf`` needs "%Id" to display
2393 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002395- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2399 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002403- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002409 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002410 was correctly parsed but parsing of subsequent arguments failed.
2411
Vinay Sajip35e3b032008-09-01 14:33:59 +00002412- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002413 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2414 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2415 when given a tuple of classes as second argument, were looking up
2416 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2417 type object.
2418
Neal Norwitz18aa3882008-08-24 05:04:52 +00002419- Fix crashes on memory allocation failure found with failmalloc.

2562-----------------
2563
Guido van Rossumf8402962008-08-20 15:01:50 +00002564- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2565 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2566 extensions do not automatically benefit from the class attribute
2567 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2568 to their tp_flags field if they care. This is a backwards
2569 compatibility feature; in 3.0, all types will use the cache by
2570 default.
2571
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002572- Keyword arguments can now follow starred arguments. (``f(a, *args,
2573 keyword=23)`` is now valid syntax.)
2574
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002575- ctypes function pointers that are COM methods have a boolean True
2576 value again.
2577
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002578- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2579 by denying s# to parse objects that have a releasebuffer procedure,
2580 and introducing s*.
2581
Georg Brandl1e13ea92008-08-11 09:07:59 +00002582- Issue #3537: Fix an assertion failure when an empty but presized dict
2583 object was stored in the freelist.
2584
Mark Dickinsonb6467572008-08-04 21:30:09 +00002585- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2586 ValueError consistently across platforms.
2587
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002588- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2589 (64bit Unix, for example), unichr() would truncate its argument and return
2590 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2591
Neal Norwitze7d8be82008-07-31 17:17:14 +00002592- Apply security patches from Apple.
2593
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002594- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2595 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2596
Antoine Pitrou92f82162008-07-25 22:22:08 +00002597- Issue #1819: function calls with several named parameters are now on
2598 average 35% faster (as measured by pybench).
2599
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002600- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2601 the python debugger steps into a class statement: the free variables (local
2602 variables defined in an outer scope) would be deleted from the outer scope.
2603
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002604- Issue #2620: Overflow checking when allocating or reallocating memory
2605 was not always being done properly in some python types and extension
2606 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2607 all been updated to perform better checks and places in the code that
2608 would previously leak memory on the error path when such an allocation
2609 failed have been fixed.

2612-------
2613
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002614- Issue #3612: Added some missing basic types in ctypes.wintypes.
2615
Benjamin Petersone977ad42008-08-20 01:42:01 +00002616- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2617 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2618
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002619- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2620 version reported by these tools does not necessarily follow the python
2621 version numbering scheme, so the module is less strict when parsing it.
2622
Nick Coghlanf70385a2008-08-18 12:42:46 +00002623- Issue #2235: Added Py3k warnings for types which will become unhashable
2624 under the stricter __hash__ inheritance rules in 3.0. Several types
2625 which did not meet the rules for hash invariants and were already
2626 unhashable in 3.0 have now been explicitly flagged as unhashable in
2627 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2628 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2629
Brett Cannon88f801d2008-08-18 00:46:22 +00002630- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2631 imported into the module but exposed as part of the module's API.
2632
Brett Cannon7b96f072008-08-18 00:41:11 +00002633- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2634
Brett Cannon46225e72008-08-18 00:36:52 +00002635- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2636
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002637- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2638
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002639- Issue #3575: Incremental decoder's decode function now takes bytearray
2640 by using 's*' instead of 't#'.
2641
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002642- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002643 fails unicode conversion on 2nd parameter. (windows only)
2644
Facundo Batista94f243a2008-08-17 03:38:39 +00002645- Issue 2464. urllib2 now supports a malformation in the URL received
2646 in a redirect.
2647
Brett Cannonabe423e2008-08-16 21:47:07 +00002648- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002649 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002650
Facundo Batistaeb90b782008-08-16 14:44:07 +00002651- Issue #2776: fixed small issue when handling an URL with double slash
2652 after a 302 response in the case of not going through a proxy.
2653
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002654- Issue #2676: in the email package, content-type parsing was hanging on
2655 pathological input because of quadratic or exponential behaviour of a
2656 regular expression.
2657
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002658- Issue #3476: binary buffered reading through the new "io" library is now
2659 thread-safe.
2660
Brett Cannonbf3157b2008-08-14 05:00:03 +00002661- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2662 since mimetools itself is deprecated. Because modules are cached, all
2663 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2664
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002665- Issue #3134: shutil referenced undefined WindowsError symbol.
2666
Robert Schuppenies14646332008-08-10 11:01:53 +00002667- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2668 menu entries were not deleted.
2669
Brett Cannon83e81842008-08-09 23:30:55 +00002670- Copied the implementation of reduce() to _functools.reduce() to have a
2671 version that did not raise a DeprecationWarning under -3.
2672
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002673- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2674 a MemoryError rather than silently stop the iteration.
2675
Guido van Rossum59ce9012008-08-09 14:55:34 +00002676- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2677 to _sre.compile() will now be rejected. This should not affect anybody
2678 since the re.compile() function never generates invalid re-bytecode.
2679
Skip Montanaroa032bf42008-08-08 22:52:51 +00002680- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2681 upon first access it can be automatically initialized from the csv file if
2682 it wasn't initialized during instantiation.
2683
Brett Cannon3aa2a492008-08-06 22:28:09 +00002684- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2685 the reload() built-in has been removed.
2686
Brett Cannon7e30b672008-08-04 21:52:25 +00002687- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002688 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00002689 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
2690 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2691 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2692 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2693 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002694
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002695- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2696 raised an AttributeError.
2697
Benjamin Peterson01a24322008-07-28 23:35:27 +00002698- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002699 asking for a specific length. This problem only affected files opened
2700 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002701
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002702- Issue #3449: Update decimal module to use most recent specification
2703 (v. 1.68) and tests (v. 2.58) from IBM.
2704
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002705- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
2706
Raymond Hettinger8c664e82008-07-25 18:43:33 +00002707- Issue 1592: Improve error reporting when operations are attempted
2708 on a closed shelf.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002712- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
2713
2714- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2715 invalid arguments.
2716
2717- Issue #3302: Fix several crashes when calling locale's gettext functions
2718 with None arguments.
2719
2720- Issue #3389: Allow resolving dotted names for handlers in logging
2721 configuration files.
2722
2723- Deprecate the sunaudio module for removal in Python 3.0.
2724
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002725- Issue #3394: zipfile.writestr sets external attributes when passed a
2726 file name rather than a ZipInfo instance, so files are extracted with
2727 mode 0600 rather than 000 under Unix.
2728
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002729- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2730 argument in python 2.5, this broke code that subclassed Popen to include its
2731 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2739-------------
2740
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002741- Issue #2235: the C API function PyObject_HashNotImplemented and its
2742 interaction with the tp_hash slot (added in 2.6b2) are now documented
2743
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002744- Issue #643841: The language reference now provides more detailed
2745 coverage of the lookup process for special methods. The disclaimers
2746 regarding lack of coverage of new-style classes have also been
2747 removed, since the coverage is now fairly reasonable.

2751================================
2752
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002753*Release date: 17-Jul-2008*
2754
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002755Core and Builtins
2756-----------------
2757
Georg Brandl3e483f62008-07-16 22:57:41 +00002758- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2759 its methods now allow for items objects that can be converted to
2760 an integer using operator.index().
2761
Mark Dickinson64b7e502008-07-16 09:40:03 +00002762- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2763 produced a ValueError instead of giving the correct float.
2764
Eric Smitha5fa5a22008-07-16 00:11:49 +00002765- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2766 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2767
Mark Dickinson7103aa42008-07-15 19:08:33 +00002768- Issue #3008: the float type has a new instance method 'float.hex'
2769 and a new class method 'float.fromhex' to convert floating-point
2770 numbers to and from hexadecimal strings, respectively.
2771
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002772- Issue #2235: __hash__ is once again inherited by default. To allow
2773 collections.Hashable to remain meaningful in the presence of the
2774 default hash implementation (object.__hash__), it is now possible
2775 to explicit block inheritance of hash by setting __hash__=None at
2776 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2777 level.
2778
Nick Coghlanb028f502008-07-13 14:52:36 +00002779- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2780 the parent module cannot be found while performing an absolute import.
2781 This means that an incorrectly defined __package__ attribute will
2782 now only prevent relative imports in that module rather than causing
2783 all imports from that module to fail.
2784
Nick Coghlan14ff9942008-07-08 14:21:42 +00002785- Issue #2517: Allow unicode messages in Exceptions again by correctly
2786 bypassing the instance dictionary when looking up __unicode__ on
2787 new-style classes.
2788
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002789- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2790 set to a custom object whose write() method happens to install
2791 another file in sys.stdout.
2792
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002793- Issue #3088: Corrected a race condition in classes derived from
2794 threading.local: the first member set by a thread could be saved in
2795 another thread's dictionary.
2796
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002797- Issue #3004: Minor change to slice.indices(): the start and stop
2798 arguments are now treated identically, making the behaviour easier
2799 to describe and understand. For example, slice(None, -10,
2800 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2801 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2802 10, -1).
2803
Georg Brandl278fc502008-07-19 12:46:12 +00002804- Issue #3219: Calling a function with repeated keyword arguments,
2805 f(a=2, a=23), would not cause a syntax error. This was a regression
2806 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002807
Georg Brandl278fc502008-07-19 12:46:12 +00002808- Issue #2862: Make int and float freelist management consistent with
2809 other freelists. Changes their CompactFreeList apis into
2810 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002811

2813-------
2814
Thomas Heller57adf222008-08-14 19:10:48 +00002815- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2816 api functions without holding the GIL, which could lead to a fatal
2817 error when they failed.
2818
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002819- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
2820
Jesse Noller7fb96402008-07-17 21:01:05 +00002821- Issue #3395: fix reference in test_multiprocessing to old debugInfo method
2822
Georg Brandla24869a2008-07-16 22:33:18 +00002823- Issue #3312: Fix two crashes in sqlite3.

2826
Jesse Noller13e9d582008-07-16 14:32:36 +00002827- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2828 ForkingPickler.register() to resolve conflict with ctypes.
2829
Vinay Sajip51e65192008-07-18 09:01:10 +00002830- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002831
Thomas Heller880f5292008-07-15 19:39:38 +00002832- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2833 a valid dlerror() message.
2834
Thomas Heller2bad6572008-07-15 17:19:50 +00002835- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2836 incomplete structure was created.
2837
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002838- Issue #3339: dummy_thread.acquire() should not return None.
2839
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002840- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2841
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002842- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002843
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002844- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2845 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002846 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002847 content-length. The problem had been corrected in the 2.4 branch, but never
2848 merged into trunk.
2849

3255 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003256 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003257
3258 This is controlled by the configure argument ``--with-universal-archs``:
3259
3260 - ``--with-universal-archs=all``: install 4-way universal
3261
3262 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3263
3264 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3265
3266 This option should be used in combination with ``--enable-universalsdk=``.
3267
3268 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003318- Issue #1631171: Re-implement the 'warnings' module in C (the
3319 original Python code has been kept as backup). This will allow for
3320 using the 'warning's machinery in such places as the parser where
3321 use of pure Python code is not possible. Both the ``showarning()``
3322 and ``formatwarning()`` gain an optional 'line' argument which is
3323 not called by default for backwards-compatibility reasons. Setting
3324 ``warnings.showwarning()`` to an implementation that lacks support
3325 for the ``line`` argument will raise a DeprecationWarning.

3349
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003350- The getpass module has been improved on Unix. It now uses /dev/tty
3351 by default and uses stderr instead of stdout. A GetPassWarning is
3352 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003388- Issue #2550: The approach used by client/server code for obtaining
3389 ports to listen on in network-oriented tests has been refined in an
3390 effort to facilitate running multiple instances of the entire
3391 regression test suite in parallel without issue.
3392 test_support.bind_port() has been fixed such that it will always
3393 return a unique port -- which wasn't always the case with the
3394 previous implementation, especially if socket options had been set
3395 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3396 new implementation of bind_port() will actually raise an exception
3397 if it is passed an AF_INET/SOCK_STREAM socket with either the
3398 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3399 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3400 the socket it's been passed. This currently only applies to
3401 Windows. This option prevents any other sockets from binding to the
3402 host/port we've bound to, thus removing the possibility of the
3403 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3404 when a second SOCK_STREAM socket binds and accepts to a host/port
3405 that's already been bound by another socket. The optional preferred
3406 port parameter to bind_port() has been removed. Under no
3407 circumstances should tests be hard coding ports!
3408
3409 test_support.find_unused_port() has also been introduced, which will
3410 pass a temporary socket object to bind_port() in order to obtain an
3411 unused port. The temporary socket object is then closed and
3412 deleted, and the port is returned. This method should only be used
3413 for obtaining an unused port in order to pass to an external program
3414 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3415 a parameter to a server-oriented class that doesn't give you direct
3416 access to the underlying socket used.
3417
3418 Finally, test_support.HOST has been introduced, which should be used
3419 for the host argument of any relevant socket calls (i.e. bind and
3420 connect).

3428 suite to run in parallel without issue.

3694Core and builtins
3695-----------------
3696
Fred Drakea8ee94b2008-03-01 02:45:07 +00003697- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003698 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003699
Georg Brandlad61bc82008-02-23 15:11:18 +00003700- Issue #2067: file.__exit__() now calls subclasses' close() method.
3701
3702- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003703
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003704- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003705 issue 215555 for a discussion.
3706
Eric Smitha73fbe72008-02-23 03:09:44 +00003707- Added the future_builtins module, which contains hex() and oct().
3708 These are the PEP 3127 version of these functions, designed to be
3709 compatible with the hex() and oct() builtins from Python 3.0. They
3710 differ slightly in their output formats from the existing, unchanged
3711 Python 2.6 builtins. The expected usage of the future_builtins
3712 module is:
3713 from future_builtins import hex, oct
3714
Eric Smith7ef40bf2008-02-20 23:34:22 +00003715- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3716 exponents for exponents with absolute value < 100. Follows C99
3717 standard. This is a change on Windows, which would use 3 digits.
3718 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3719 so that any alterations it does to the resulting string will be
3720 available in stringlib/formatter.h (for float.__format__).
3721
Eric Smith5a3c1352008-02-19 13:21:56 +00003722- Implemented PEP 3101, Advanced String Formatting. This adds a new
3723 builtin format(); a format() method for str and unicode; a
3724 __format__() method to object, str, unicode, int, long, float, and
3725 datetime; the class string.Formatter; and the C API
3726 PyObject_Format().
3727
Georg Brandl3ee81df2008-05-17 18:14:43 +00003728- Fixed several potential crashes, all caused by specially crafted
3729 __del__ methods exploiting objects in temporarily inconsistent
3730 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003731
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003732- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003733 prevent a possible crash: an Abstract Base Class would try to access
3734 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003735
Georg Brandl3ee81df2008-05-17 18:14:43 +00003736- Fixed repr() and str() of complex numbers with infinity or nan as
3737 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003738
Georg Brandl3ee81df2008-05-17 18:14:43 +00003739- Clear all free lists during a gc.collect() of the highest generation
3740 in order to allow pymalloc to free more arenas. Python may give back
3741 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003742
Georg Brandl3ee81df2008-05-17 18:14:43 +00003743- Issue #2045: Fix an infinite recursion triggered when printing a
3744 subclass of collections.defaultdict, if its default_factory is set
3745 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003746
Christian Heimesf75dbef2008-02-08 00:11:31 +00003747- Fixed a minor memory leak in dictobject.c. The content of the free
3748 list was not freed on interpreter shutdown.
3749
Georg Brandl3ee81df2008-05-17 18:14:43 +00003750- Limit free list of method and builtin function objects to 256
3751 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003752
Georg Brandl3ee81df2008-05-17 18:14:43 +00003753- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3754 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003755 to compact the internal free lists of pre-allocted ints and floats.
3756
Georg Brandl3ee81df2008-05-17 18:14:43 +00003757- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3758 calls. Python expected the return type int but the fork familie
3759 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003760
Georg Brandl3ee81df2008-05-17 18:14:43 +00003761- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3762 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003763
Georg Brandl3ee81df2008-05-17 18:14:43 +00003764- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3765 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003766
Georg Brandl3ee81df2008-05-17 18:14:43 +00003767- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3768 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003769
Georg Brandl3ee81df2008-05-17 18:14:43 +00003770- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3771 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003772
Georg Brandl3ee81df2008-05-17 18:14:43 +00003773- Patch #1473257: generator objects gain a gi_code attribute. This is
3774 the same object as the func_code attribute of the function that
3775 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003776
Georg Brandl3ee81df2008-05-17 18:14:43 +00003777- Issue #1920: "while 0" statements were completely removed by the
3778 compiler, even in the presence of an "else" clause, which is
3779 supposed to be run when the condition is false. Now the compiler
3780 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003781
Guido van Rossumeead05f2008-01-24 18:21:02 +00003782- A few crashers fixed: weakref_in_del.py (issue #1377858);
3783 loosing_dict_ref.py (issue #1303614, test67.py);
3784 borrowed_ref_[34].py (not in tracker).
3785
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003786- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003787 suppressed while an extension is loaded by calling SetErrorMode in
3788 dynload_win.c. The error is still reported properly.
3789
Georg Brandl3ee81df2008-05-17 18:14:43 +00003790- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003791 several extension methods and modules do not work without unicode
3792 support.
3793
Georg Brandl26543b12008-01-21 18:36:51 +00003794- Issue #1882: when compiling code from a string, encoding cookies in the
3795 second line of code were not always recognized correctly.
3796
Georg Brandl14404b62008-01-19 19:27:05 +00003797- Issue #1679: "0x" was taken as a valid integer literal.
3798
Georg Brandl6caad7d2008-01-26 14:19:22 +00003799- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003800 added.
3801
Christian Heimesc94e2b52008-01-14 04:13:37 +00003802- sys.float_info / PyFloat_GetInfo: The floating point information
3803 object was converted from a dict to a specialized structseq object.
3804
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805- Patch #1816: Added sys.flags structseq. It exposes the status of
3806 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003807
Georg Brandl3ee81df2008-05-17 18:14:43 +00003808- Objects/structseq.c: Implemented new structseq representation. The
3809 patch makes structseqs (e.g. the return value of os.stat) more
3810 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003811
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812- Patch #1700288: added a type attribute cache that caches method
3813 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003814
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003815- Bug #1776: __import__() no longer accepts filenames on any platform.
3816 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003817
Georg Brandlaed6c662008-01-07 17:25:53 +00003818- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3819
Georg Brandl3ee81df2008-05-17 18:14:43 +00003820- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3821 envvar and sys.dont_write_bytecode attribute. All these can be set
3822 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003823
Georg Brandl3ee81df2008-05-17 18:14:43 +00003824- Improve some exception messages when Windows fails to load an
3825 extension module. Now we get for example '%1 is not a valid Win32
3826 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003827
Georg Brandl3ee81df2008-05-17 18:14:43 +00003828- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003830- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3831 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003832
Christian Heimes0a8143f2007-12-18 23:22:54 +00003833- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003834 and INF. float("nan"), float("inf") and float("-inf") now work on
3835 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- Compiler now generates simpler and faster code for dictionary
3838 literals. The oparg for BUILD_MAP now indicates an estimated
3839 dictionary size. There is a new opcode, STORE_MAP, for adding
3840 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003841
Georg Brandl3ee81df2008-05-17 18:14:43 +00003842- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003850- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003851 SystemError.
3852
Nick Coghlanef01d822007-12-03 12:55:17 +00003853- PEP 366: Allow explicit relative imports when executing modules
3854 inside packages with the -m switch via a new module level
3855 __package__ attribute.
3856

3858 running, and if the deallocation of its frames somehow calls the
3859 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003860

3870 file can now be directly executed by passing their name to the
3871 interpreter. The directory/zipfile is automatically inserted as the
3872 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003873
Georg Brandl3ee81df2008-05-17 18:14:43 +00003874- Issue #1265: Fix a problem with sys.settrace, if the tracing
3875 function uses a generator expression when at the same time the
3876 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003877
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003878- sets and frozensets now have an isdisjoint() method.
3879
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003880- optimize the performance of builtin.sum().

3883
Georg Brandl3ee81df2008-05-17 18:14:43 +00003884- The enumerate() builtin function is no longer bounded to sequences
3885 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3886 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003887
Georg Brandl3ee81df2008-05-17 18:14:43 +00003888- Issue #1686386: Tuple's tp_repr did not take into account the
3889 possibility of having a self-referential tuple, which is possible
3890 from C code. Nor did object's tp_str consider that a type's tp_str
3891 could do something that could lead to an inifinite recursion.
3892 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3893 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003894
Georg Brandl3ee81df2008-05-17 18:14:43 +00003895- Issue #1164: It was possible to trigger deadlock when using the
3896 'print' statement to write to a file since the GIL was not released
3897 as needed. Now PyObject_Print() does the right thing along with
3898 various tp_print implementations of the built-in types and those in
3899 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003900
Georg Brandl3ee81df2008-05-17 18:14:43 +00003901- Issue #1147: Exceptions were directly allowing string exceptions in
3902 their throw() method even though string exceptions no longer
3903 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003904
Georg Brandl3ee81df2008-05-17 18:14:43 +00003905- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003908- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003909 PyObject_Call() never calling back out to Python code to trigger
3910 recursion depth updates/checks. Required the creation of a static
3911 RuntimeError instance in case normalizing an exception put the

Neal Norwitz0ac60192007-05-27 04:08:54 +00003928- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003929 __*__ attributes. (Some already existed, e.g., __doc__ and
3930 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003931
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003932- Add -3 option to the interpreter to warn about features that are

3937
Collin Winter62903052007-05-18 23:11:24 +00003938- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003939 "except E as target:". This is to provide forwards compatibility
3940 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003941
Brett Cannon229cee22007-05-05 01:34:02 +00003942- Deprecate BaseException.message as per PEP 352.
3943
Georg Brandl3ee81df2008-05-17 18:14:43 +00003944- Issue #1303614: don't expose object's __dict__ when the dict is

3946
Vinay Sajip8549ce32007-05-06 17:53:37 +00003947- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003948 setting a plain string, ie don't expand to single letter identifiers.
3949
Raymond Hettinger13936692007-04-11 18:40:58 +00003950- Request #1191699: Slices can now be pickled.
3951
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003952- Request #1193128: str.translate() now allows a None argument for

3960
Guido van Rossum143b5642007-03-23 04:58:42 +00003961- Bug #1683368: The object.__init__() and object.__new__() methods are
3962 now stricter in rejecting excess arguments. The only time when
3963 either allows excess arguments is when it is not overridden and the
3964 other one is. For backwards compatibility, when both are
3965 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003966 warning later). Also, type.__init__() insists on the same signature
3967 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003968
Georg Brandl3ee81df2008-05-17 18:14:43 +00003969- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3970 object to complex using its __complex__() method before falling back
3971 to the __float__() method. Therefore, the functions in the cmath
3972 module now can operate on objects that define a __complex__()
3973 method.

3990
Georg Brandl7b9c5552007-03-12 14:30:05 +00003991- Bug #1678647: write a newline after printing an exception in any
3992 case, even when converting the value to a string failed.
3993
Georg Brandl871f1bc2007-03-12 13:17:36 +00003994- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003995 its argument, if it exists. If not, it will work like before. This
3996 allows customizing the output of dir() in the presence of a
3997 __getattr__().

4007 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004008
Georg Brandlaa2321b2007-03-07 00:40:28 +00004009- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004010 makes the filenames the warning module prints much more sensible
4011 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004012

Georg Brandl0fca97a2007-03-05 22:28:08 +00004024- Patch #1674228: when assigning a slice (old-style), check for the
4025 sq_ass_slice instead of the sq_slice slot.
4026
Georg Brandl3ee81df2008-05-17 18:14:43 +00004027- When printing an unraisable error, don't print exceptions. before

4656 incompatibility since it never made sense with ordinary subclasses
4657 -- the failure just occurred later, with a more cumbersome
4658 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004939- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4940 with RFC 3207 and forgets any knowledge obtained from the server not
4941 obtained from the TLS negotiation itself. Patch contributed by Bill
4942 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004943
Georg Brandl3ee81df2008-05-17 18:14:43 +00004944- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004945 that the SMTP.starttls() caller no longer needs to call ehlo()
4946 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004947 does not claim to support starttls. Adds the
4948 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5029 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5030 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005047 time so that opening a database previously created with the DB_DUP
5048 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5049 opens. Specifically: dictionary assignment to a DB object will
5050 replace all values for a given key when the database allows
5051 duplicate values. DB users should use DB.put(k, v) when they want
5052 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005053

5059 characters with ASCII value less than 32. Also, it correctly quotes
5060 dots only if they occur on a single line, as opposed to the previous
5061 behavior of quoting dots if they are the second character of any
5062 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005063

Georg Brandl3ee81df2008-05-17 18:14:43 +00005379- Makefile.pre.in(buildbottest): Run an optional script
5380 pybuildbot.identify to include some information about the build
5381 environment.

5385-----
5386
Georg Brandl3ee81df2008-05-17 18:14:43 +00005387- Unified naming convention for free lists and their limits. All free
5388 lists in Object/ are named ``free_list``, the counter ``numfree``
5389 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5390 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005391
Georg Brandl3ee81df2008-05-17 18:14:43 +00005392- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5393 to ``PyTuple_SetItem``, it can be used to populate a brand new
5394 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005395
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005396- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005397
Georg Brandl3ee81df2008-05-17 18:14:43 +00005398- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5399 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5400 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005401
5402- Patch #1720595: add T_BOOL to the range of structmember types.
5403
5404- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5405 ``PyFloat_GetInfo()`` to the float API.
5406
Georg Brandl3ee81df2008-05-17 18:14:43 +00005407- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5408 of w# format code incorrectly truncated the length to an int, even
5409 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5410 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005411
Georg Brandl3ee81df2008-05-17 18:14:43 +00005412- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5413 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005414
Georg Brandl3ee81df2008-05-17 18:14:43 +00005415- PEP 3123: Provide forward compatibility with Python 3.0, while
5416 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5417 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005418
Georg Brandl3ee81df2008-05-17 18:14:43 +00005419- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5420 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005421
5422- Patch #1733960: Allow T_LONGLONG to accept ints.
5423
5424- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5425
Christian Heimes000a0742008-01-03 22:16:32 +00005426- Added a new API function ``PyImport_ImportModuleNoBlock``.
5427
Georg Brandl6caad7d2008-01-26 14:19:22 +00005428- Bug #1637022: Prefix AST symbols with _Py_.
5429
5430- Fix some leftovers from the conversion from int to Py_ssize_t
5431 (relevant to strings and sequences of more than 2**31 items).
5432
5433- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5434 outside of pystate.c and should not be necessary.
5435
Georg Brandl3ee81df2008-05-17 18:14:43 +00005436- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5437 absolute imports. In earlier versions they might have used relative
5438 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005439
Georg Brandl3ee81df2008-05-17 18:14:43 +00005440- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5441 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005442
Georg Brandl3ee81df2008-05-17 18:14:43 +00005443- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5444 macro so it can be used as an expression.

5449
Georg Brandl3ee81df2008-05-17 18:14:43 +00005450- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5451 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5452 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5453 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005454
Georg Brandl3ee81df2008-05-17 18:14:43 +00005455- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5456 _CRT_NONSTDC_NO_DEPRECATE.
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00005457
Martin v. Löwisd476a402007-10-12 08:56:52 +00005458- Bug #1216: Restore support for Visual Studio 2002.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005468- Removed the macfs module. It had been deprecated since Python 2.5.
5469 This lead to the deprecation of macostools.touched() as it relied
5470 solely on macfs and was a no-op under OS X.
