313Core and Builtins
314-----------------
315
Benjamin Petersonecdae192010-01-04 00:43:01 +0000316- The __complex__ method is now looked up on the class of instances to make it
317 consistent with other special methods.
318
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000319- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
320 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
321
Mark Dickinson1b34d252010-01-01 17:27:30 +0000322- Issue #5080: A number of functions and methods previously produced a
323 DeprecationWarning when passed a float argument where an integer was
324 expected. These functions and methods now raise TypeError instead.
325 The majority of the effects of this change are in the extension
326 modules, but some core functions and methods are affected: notably
327 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
328 methods.
329
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000330- Issue #7604: Deleting an unset slotted attribute did not raise an
331 AttributeError.
332
Mark Dickinson99d652e2009-12-30 12:12:23 +0000333- Issue #7534: Fix handling of IEEE specials (infinities, nans,
334 negative zero) in ** operator. The behaviour now conforms to that
335 described in C99 Annex F.
336
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000337- Issue #7579: the msvcrt module now has docstrings for all its functions.
338
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000339- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
340 used to drop the time part of the result.
341
Mark Dickinson46572832009-12-27 14:55:57 +0000342- Issue #1811: improve accuracy and cross-platform consistency for
343 true division of integers: the result of a/b is now correctly
344 rounded for ints a and b (at least on IEEE 754 platforms), and in
345 particular does not depend on the internal representation of a long.
346
Ezio Melottif84caf42009-12-24 22:25:17 +0000347- Issue #6108: unicode(exception) and str(exception) should return the same
348 message when only __str__ (and not __unicode__) is overridden in the subclass.
349
Ronald Oussoren92919a62009-12-24 13:30:58 +0000350- Issue #6834: replace the implementation for the 'python' and 'pythonw'
351 executables on OSX.
352
353 These executables now work properly with the arch(1) command:
354 ``arch -ppc python`` will start a universal binary version of python
355 in PPC mode (unlike previous releases).
356
R. David Murray0a0a1a82009-12-14 16:28:26 +0000357- Issue #1680159: unicode coercion during an 'in' operation no longer masks
358 the underlying error when the coercion fails for the left hand operand.
359
Benjamin Peterson4895af42009-12-13 16:36:53 +0000360- Issue #7491: Metaclass's __cmp__ method was ignored.
361
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000362- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +0000363 in the middle of populating a tuple. Patch by Florent Xicluna.

368
Jesse Noller654ade32010-01-27 03:05:57 +0000369- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
370 allowing for a maximum number of tasks within the pool to be completed by
371 the worker before that worker is terminated, and a new one created to
372 replace it.
373
Tarek Ziadéc25417f2010-01-08 23:42:23 +0000374- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes
375 gcc when it has a fully qualified configuration prefix. Initial patch
376 by Arfrever.
377
Antoine Pitrou80157252010-01-08 19:20:17 +0000378- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
379 renaming of `cPickle` to `pickle`. The warning was annoying since there's
380 no alternative to cPickle if you care about performance. Patch by Florent
381 Xicluna.
382
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000383- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

387 when using the -3 flag. Patch by Florent Xicluna.
388
Antoine Pitrou673ddf92010-01-03 22:29:56 +0000389- Issue #7471: Improve the performance of GzipFile's buffering mechanism,
390 and make it implement the `io.BufferedIOBase` ABC to allow for further
391 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
392
393- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000394 parameter to allow specifying where your connections come from.
395
Gregory P. Smith79a3eb12010-01-03 01:29:44 +0000396- socket.create_connection now accepts an optional source_address parameter.
397
Ezio Melotti569e61f2009-12-30 06:14:51 +0000398- Issue #5511: now zipfile.ZipFile can be used as a context manager.
399 Initial patch by Brian Curtin.
400
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +0000401- Distutils now correctly identifies the build architecture as "x86_64"
Ezio Melotti569e61f2009-12-30 06:14:51 +0000402 when building on OSX 10.6 without "-arch" flags.

406
Tarek Ziadé2421d562009-12-20 23:23:34 +0000407- Issue #7552: Removed line feed in the base64 Authorization header in
408 the Distutils upload command to avoid an error when PyPI reads it.
409 This occurs on long passwords. Initial patch by JP St. Pierre.
410
411- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000412 Patch by Tatsuhiro Tsujikawa.
413
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000414- Issue #7349: Make methods of file objects in the io module accept None as an
415 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
416 the same as passing no argument.
417
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000418- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
419 like other file objects.
420
Lars Gustäbel92ca7562009-12-13 11:32:27 +0000421- Issue #7357: tarfile no longer suppresses fatal extraction errors by
422 default.
423
Vinay Sajip5cc4e2a2009-12-11 09:16:01 +0000424- Issue #7470: logging: fix bug in Unicode encoding fallback.
425
R. David Murray93321f32009-12-09 15:15:31 +0000426- Issue #5949: fixed IMAP4_SSL hang when the IMAP server response is
427 missing proper end-of-line termination.
428
Tarek Ziadé2421d562009-12-20 23:23:34 +0000429- Issue #7457: added a read_pkg_file method to

439 analogous to PyLong_AsLongAndOverflow.
440
Mark Dickinson1b34d252010-01-01 17:27:30 +0000441- Issue #5080: The argument parsing functions PyArg_ParseTuple,
442 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
443 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
444 arguments for integer format codes (other than 'L'): previously an
445 attempt to pass a float resulted in a DeprecationWarning; now it
446 gives a TypeError. For the 'L' format code (which previously had no
447 warning) there is now a DeprecationWarning.
448
Georg Brandl740cdc32009-12-28 08:34:58 +0000449- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000492- Issue #7419: setlocale() could crash the interpreter on Windows when called
493 with invalid values.
494
Eric Smithc4ab8332009-11-29 17:40:57 +0000495- Issue #3382: 'F' formatting for float and complex now convert the
496 result to upper case. This only affects 'inf' and 'nan', since 'f'
497 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000498
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000499- Remove switch from "%f" formatting to "%g" formatting for floats
500 larger than 1e50 in absolute value.
501
Mark Dickinson18cfada2009-11-23 18:46:41 +0000502- Remove restrictions on precision when formatting floats. E.g.,
503 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
504 requested 120 significant digits instead.
505
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000506- Add Py3k warnings for parameter names in parenthesis.
507

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000510- Issue #7085: Fix crash when importing some extensions in a thread
511 on MacOSX 10.6.
512
Mark Dickinsonb678de82009-11-19 18:41:49 +0000513- Issue #7117: repr(x) for a float x returns a result based on the
514 shortest decimal string that's guaranteed to round back to x under
515 correct rounding (with round-half-to-even rounding mode).
516 Previously it gave a string based on rounding x to 17 decimal digits.
517 repr(x) for a complex number behaves similarly. On platforms where
518 the correctly-rounded strtod and dtoa code is not supported (see below),
519 repr is unchanged.
520
521- Issue #7117: On almost all platforms: float-to-string and
522 string-to-float conversions within Python are now correctly rounded.
523 Places these conversions occur include: str for floats and complex
524 numbers; the float and complex constructors; old-style and new-style
525 numeric formatting; serialization and deserialization of floats and
526 complex numbers using marshal, pickle and json; parsing of float and
527 imaginary literals in Python code; Decimal-to-float conversion.
528
529 The conversions use a Python-adapted version of David Gay's
530 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
531 functions. This code is supported on Windows, and on Unix-like
532 platforms using gcc, icc or suncc as the C compiler. There may be a
533 small number of platforms on which correct operation of this code
534 cannot be guaranteed, so the code is not used: notably, this applies
535 to platforms where the C double format is not IEEE 754 binary64, and
536 to platforms on x86 hardware where the x87 FPU is set to 64-bit
537 precision and Python's configure script is unable to determine how
538 to change the FPU precision. On these platforms conversions use the
539 platform strtod and dtoa, as before.
540
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000541- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000542 now uses the correctly-rounded string <-> float conversions
543 described above (when available), and so produces correctly rounded
544 results that will display nicely under the float repr. There are
545 two related small changes: (1) round now accepts any class with an
546 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000547 floats for the second argument), and (2) an excessively large second
548 integer argument (e.g., round(1.234, 10**100)) no longer raises an
549 exception.

678 statement and correctly lookup the __enter__ and __exit__ special methods.
679
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000680- Issue #5829: complex("1e500") no longer raises OverflowError. This

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000691- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
692 (1) inf and nan strings with trailing whitespace were incorrectly
693 rejected; (2) parsing of strings representing infinities and nans
694 was locale aware; and (3) the interpretation of fromhex('-nan')
695 didn't match that of float('-nan').
696
Eric Smitha985a3a2009-05-05 18:26:08 +0000697- Issue #5920: For float.__format__, change the behavior with the
698 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
699 to be like 'g' but with at least one decimal point and with a
700 default precision of 12. Previously, the behavior the same but with
701 a default precision of 6. This more closely matches str(), and
702 reduces surprises when adding alignment flags to the empty
703 presentation type. This also affects the new complex.__format__ in
704 the same way.
705
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000706- Issue #5890: in subclasses of 'property' the __doc__ attribute was

747
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000748- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000749 was giving 5e15+2; round(-0.0) was losing the sign of the zero.

767
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000768- Issue #4688: Add a heuristic so that tuples and dicts containing only
769 untrackable objects are not tracked by the garbage collector. This can
770 reduce the size of collections and therefore the garbage collection overhead
771 on long-running programs, depending on their particular use of datatypes.
772
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000773- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

775 are now between 50% and 150% faster.
776
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000777- Issue #4258: Make it possible to use base 2**30 instead of base
778 2**15 for the internal representation of integers, for performance
779 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
780 --enable-big-digits option to configure, which overrides the
781 default. Add sys.long_info structseq to provide information about
782 the internal format.
783
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000784- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
785 result traceback.__members__ no longer exists.)
786
Mark Dickinson6b265f12009-03-18 16:07:26 +0000787- Issue #4474: PyUnicode_FromWideChar now converts characters outside
788 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

790
Eric Smith6f42edb2009-03-14 11:57:26 +0000791- Issue #5237: Allow auto-numbered fields in str.format(). For
792 example: '{} {}'.format(1, 2) == '1 2'.
793
Brett Cannon6c4cff02009-03-11 04:51:06 +0000794- Issue #3652: Make the 'line' argument for warnings.showwarning() a
795 requirement. Means the DeprecationWarning from Python 2.6 can go away.
796
Eric Smithe9fb6862009-02-20 14:02:36 +0000797- Issue #5247: Improve error message when unknown format codes are
798 used when using str.format() with str, unicode, long, int, and
799 float arguments.
800

802 for ints and longs.
803
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000804- Issue #5260: Long integers now consume less memory: average
805 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
806 on a 64-bit system.
807
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000808- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
809 rotating the object pointer by 4 bits to the right.

815
Georg Brandl29c6a282009-04-05 20:23:13 +0000816- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000817 were suppressing all exceptions. These include list(), filter(), map(),
818 zip(), and bytearray().
819
Benjamin Peterson596d3062009-01-19 15:42:23 +0000820- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

848 an existing .py counterpart, override the co_filename attributes of all
849 code objects if the original filename is obsolete (which can happen if the
850 file has been renamed, moved, or if it is accessed through different paths).

Vinay Sajip213faca2008-12-03 23:22:58 +0000906- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000907 method on file objects with closefd=False. The file descriptor is still
908 kept open but the file object behaves like a closed file. The ``FileIO``
909 object also got a new readonly attribute ``closefd``.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000932- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
933 returned a path longer than MAX_PATH. (But It's doubtful this code path is
934 really executed because I cannot move to such directory on win2k)
935
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000936- Issue #4069: When set.remove(element) is used with a set element, the element
937 is temporarily replaced with an equivalent frozenset. But the eventual
938 KeyError would always report the empty frozenset([]) as the missing key. Now
939 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000959- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
960 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
961 step. This avoids problems with counting UTF-8 bytes that ignores the effect
962 of using the replace error handler in PyUnicode_DecodeUTF8().
963
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000964- Issue #3739: The unicode-internal encoder now reports the number of characters

966
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000967- Issue #2422: When compiled with the ``--with-valgrind`` option, the
968 pymalloc allocator will be automatically disabled when running under
969 Valgrind. This gives improved memory leak detection when running
970 under Valgrind, while taking advantage of pymalloc at other times.

2207 leak-chasing test runs give sensible results. The previous method of
2208 reaping threads could return successfully while some Thread objects were

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002350- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2351
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002352- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2353 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2354 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2355 ``printf`` function, whereas PyString_FromFormat has an independent
2356 implementation and uses "%zd" on all platforms for size_t values.
2357 This makes a difference on win64, where ``printf`` needs "%Id" to display
2358 64bit values.
2359
Benjamin Peterson97179b02008-09-09 20:55:01 +00002360- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2364 object; previously an int would be returned for small values. the __long__
2365 method is allowed to return either an int or a long, but the behaviour of
2366 float objects should not change to respect backward compatibility.
2367
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002368- Issue #3751: str.rpartition would perform a left-partition when called with
2369 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002374 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002375 was correctly parsed but parsing of subsequent arguments failed.
2376
Vinay Sajip35e3b032008-09-01 14:33:59 +00002377- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002378 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2379 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2380 when given a tuple of classes as second argument, were looking up
2381 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2382 type object.
2383
Neal Norwitz18aa3882008-08-24 05:04:52 +00002384- Fix crashes on memory allocation failure found with failmalloc.
2385
2386- Fix memory leaks found with valgrind and update suppressions file.

2453 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2454 for catch_warnings() also led to an improvement in the raising of a

2527-----------------
2528
Guido van Rossumf8402962008-08-20 15:01:50 +00002529- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2530 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2531 extensions do not automatically benefit from the class attribute
2532 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2533 to their tp_flags field if they care. This is a backwards
2534 compatibility feature; in 3.0, all types will use the cache by
2535 default.
2536
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002537- Keyword arguments can now follow starred arguments. (``f(a, *args,
2538 keyword=23)`` is now valid syntax.)
2539
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002540- ctypes function pointers that are COM methods have a boolean True
2541 value again.
2542
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002543- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2544 by denying s# to parse objects that have a releasebuffer procedure,
2545 and introducing s*.
2546
Georg Brandl1e13ea92008-08-11 09:07:59 +00002547- Issue #3537: Fix an assertion failure when an empty but presized dict
2548 object was stored in the freelist.
2549
Mark Dickinsonb6467572008-08-04 21:30:09 +00002550- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2551 ValueError consistently across platforms.
2552
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002553- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2554 (64bit Unix, for example), unichr() would truncate its argument and return
2555 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2556
Neal Norwitze7d8be82008-07-31 17:17:14 +00002557- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002559- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2560 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2561
Antoine Pitrou92f82162008-07-25 22:22:08 +00002562- Issue #1819: function calls with several named parameters are now on
2563 average 35% faster (as measured by pybench).
2564
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002565- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2566 the python debugger steps into a class statement: the free variables (local
2567 variables defined in an outer scope) would be deleted from the outer scope.
2568
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002569- Issue #2620: Overflow checking when allocating or reallocating memory
2570 was not always being done properly in some python types and extension
2571 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2572 all been updated to perform better checks and places in the code that
2573 would previously leak memory on the error path when such an allocation
2574 failed have been fixed.

2580
Benjamin Petersone977ad42008-08-20 01:42:01 +00002581- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2582 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2583
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002584- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2585 version reported by these tools does not necessarily follow the python
2586 version numbering scheme, so the module is less strict when parsing it.
2587
Nick Coghlanf70385a2008-08-18 12:42:46 +00002588- Issue #2235: Added Py3k warnings for types which will become unhashable
2589 under the stricter __hash__ inheritance rules in 3.0. Several types
2590 which did not meet the rules for hash invariants and were already
2591 unhashable in 3.0 have now been explicitly flagged as unhashable in
2592 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2593 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2594
Brett Cannon88f801d2008-08-18 00:46:22 +00002595- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2596 imported into the module but exposed as part of the module's API.
2597

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002604- Issue #3575: Incremental decoder's decode function now takes bytearray
2605 by using 's*' instead of 't#'.
2606
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002607- Issue #2222: Fixed reference leak when occurred os.rename()

2617 after a 302 response in the case of not going through a proxy.
2618
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002619- Issue #2676: in the email package, content-type parsing was hanging on
2620 pathological input because of quadratic or exponential behaviour of a
2621 regular expression.
2622
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002623- Issue #3476: binary buffered reading through the new "io" library is now
2624 thread-safe.
2625
Brett Cannonbf3157b2008-08-14 05:00:03 +00002626- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2627 since mimetools itself is deprecated. Because modules are cached, all
2628 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2629
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002630- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002632- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2633 menu entries were not deleted.
2634
Brett Cannon83e81842008-08-09 23:30:55 +00002635- Copied the implementation of reduce() to _functools.reduce() to have a
2636 version that did not raise a DeprecationWarning under -3.
2637
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002638- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2639 a MemoryError rather than silently stop the iteration.
2640
Guido van Rossum59ce9012008-08-09 14:55:34 +00002641- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2642 to _sre.compile() will now be rejected. This should not affect anybody
2643 since the re.compile() function never generates invalid re-bytecode.
2644
Skip Montanaroa032bf42008-08-08 22:52:51 +00002645- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2646 upon first access it can be automatically initialized from the csv file if
2647 it wasn't initialized during instantiation.
2648
Brett Cannon3aa2a492008-08-06 22:28:09 +00002649- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2650 the reload() built-in has been removed.
2651
Brett Cannon7e30b672008-08-04 21:52:25 +00002652- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002653 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2661 raised an AttributeError.
2662
Benjamin Peterson01a24322008-07-28 23:35:27 +00002663- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002664 asking for a specific length. This problem only affected files opened
2665 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002666

2689
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002690- Issue #3394: zipfile.writestr sets external attributes when passed a
2691 file name rather than a ZipInfo instance, so files are extracted with
2692 mode 0600 rather than 000 under Unix.
2693
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002694- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2695 argument in python 2.5, this broke code that subclassed Popen to include its
2696 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2705
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002706- Issue #2235: the C API function PyObject_HashNotImplemented and its
2707 interaction with the tp_hash slot (added in 2.6b2) are now documented
2708
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002709- Issue #643841: The language reference now provides more detailed
2710 coverage of the lookup process for special methods. The disclaimers
2711 regarding lack of coverage of new-style classes have also been
2712 removed, since the coverage is now fairly reasonable.

2716================================
2717
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002718*Release date: 17-Jul-2008*
2719
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002720Core and Builtins
2721-----------------
2722
Georg Brandl3e483f62008-07-16 22:57:41 +00002723- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2724 its methods now allow for items objects that can be converted to
2725 an integer using operator.index().
2726
Mark Dickinson64b7e502008-07-16 09:40:03 +00002727- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2728 produced a ValueError instead of giving the correct float.
2729
Eric Smitha5fa5a22008-07-16 00:11:49 +00002730- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2731 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2732
Mark Dickinson7103aa42008-07-15 19:08:33 +00002733- Issue #3008: the float type has a new instance method 'float.hex'
2734 and a new class method 'float.fromhex' to convert floating-point
2735 numbers to and from hexadecimal strings, respectively.
2736
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002737- Issue #2235: __hash__ is once again inherited by default. To allow
2738 collections.Hashable to remain meaningful in the presence of the
2739 default hash implementation (object.__hash__), it is now possible
2740 to explicit block inheritance of hash by setting __hash__=None at
2741 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2742 level.
2743
Nick Coghlanb028f502008-07-13 14:52:36 +00002744- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2745 the parent module cannot be found while performing an absolute import.
2746 This means that an incorrectly defined __package__ attribute will
2747 now only prevent relative imports in that module rather than causing
2748 all imports from that module to fail.
2749
Nick Coghlan14ff9942008-07-08 14:21:42 +00002750- Issue #2517: Allow unicode messages in Exceptions again by correctly
2751 bypassing the instance dictionary when looking up __unicode__ on
2752 new-style classes.
2753
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002754- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2755 set to a custom object whose write() method happens to install
2756 another file in sys.stdout.
2757
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002758- Issue #3088: Corrected a race condition in classes derived from
2759 threading.local: the first member set by a thread could be saved in
2760 another thread's dictionary.
2761
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002762- Issue #3004: Minor change to slice.indices(): the start and stop
2763 arguments are now treated identically, making the behaviour easier
2764 to describe and understand. For example, slice(None, -10,
2765 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2766 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2767 10, -1).
2768
Georg Brandl278fc502008-07-19 12:46:12 +00002769- Issue #3219: Calling a function with repeated keyword arguments,
2770 f(a=2, a=23), would not cause a syntax error. This was a regression
2771 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002772
Georg Brandl278fc502008-07-19 12:46:12 +00002773- Issue #2862: Make int and float freelist management consistent with
2774 other freelists. Changes their CompactFreeList apis into
2775 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002776

2778-------
2779
Thomas Heller57adf222008-08-14 19:10:48 +00002780- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2781 api functions without holding the GIL, which could lead to a fatal
2782 error when they failed.
2783
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002784- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002792- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2793 ForkingPickler.register() to resolve conflict with ctypes.
2794
Vinay Sajip51e65192008-07-18 09:01:10 +00002795- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002796
Thomas Heller880f5292008-07-15 19:39:38 +00002797- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2798 a valid dlerror() message.
2799
Thomas Heller2bad6572008-07-15 17:19:50 +00002800- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2801 incomplete structure was created.
2802
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002803- Issue #3339: dummy_thread.acquire() should not return None.

2806
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002807- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002808
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002809- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2810 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002811 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002812 content-length. The problem had been corrected in the 2.4 branch, but never
2813 merged into trunk.
2814
Georg Brandle78fbcc2008-07-05 10:13:36 +00002815- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00002823 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002824
Vinay Sajip51e65192008-07-18 09:01:10 +00002825- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002826 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002827
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002828- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2829 handling is now the same as that of other special attributes like __name__).
2830
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002831- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2832 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00003221 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003222
3223 This is controlled by the configure argument ``--with-universal-archs``:
3224
3225 - ``--with-universal-archs=all``: install 4-way universal
3226
3227 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3228
3229 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3230
3231 This option should be used in combination with ``--enable-universalsdk=``.
3232
3233 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 +00003283- Issue #1631171: Re-implement the 'warnings' module in C (the
3284 original Python code has been kept as backup). This will allow for
3285 using the 'warning's machinery in such places as the parser where
3286 use of pure Python code is not possible. Both the ``showarning()``
3287 and ``formatwarning()`` gain an optional 'line' argument which is
3288 not called by default for backwards-compatibility reasons. Setting
3289 ``warnings.showwarning()`` to an implementation that lacks support
3290 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003353- Issue #2550: The approach used by client/server code for obtaining
3354 ports to listen on in network-oriented tests has been refined in an
3355 effort to facilitate running multiple instances of the entire
3356 regression test suite in parallel without issue.
3357 test_support.bind_port() has been fixed such that it will always
3358 return a unique port -- which wasn't always the case with the
3359 previous implementation, especially if socket options had been set
3360 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3361 new implementation of bind_port() will actually raise an exception
3362 if it is passed an AF_INET/SOCK_STREAM socket with either the
3363 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3364 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3365 the socket it's been passed. This currently only applies to
3366 Windows. This option prevents any other sockets from binding to the
3367 host/port we've bound to, thus removing the possibility of the
3368 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3369 when a second SOCK_STREAM socket binds and accepts to a host/port
3370 that's already been bound by another socket. The optional preferred
3371 port parameter to bind_port() has been removed. Under no
3372 circumstances should tests be hard coding ports!
3373
3374 test_support.find_unused_port() has also been introduced, which will
3375 pass a temporary socket object to bind_port() in order to obtain an
3376 unused port. The temporary socket object is then closed and
3377 deleted, and the port is returned. This method should only be used
3378 for obtaining an unused port in order to pass to an external program
3379 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3380 a parameter to a server-oriented class that doesn't give you direct
3381 access to the underlying socket used.
3382
3383 Finally, test_support.HOST has been introduced, which should be used
3384 for the host argument of any relevant socket calls (i.e. bind and
3385 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003386
3387 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003388 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3390 test_asynchat and test_socket_ssl.
3391
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392 It is now possible for multiple instances of the regression test
3393 suite to run in parallel without issue.

3659Core and builtins
3660-----------------
3661
Fred Drakea8ee94b2008-03-01 02:45:07 +00003662- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003663 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003664
Georg Brandlad61bc82008-02-23 15:11:18 +00003665- Issue #2067: file.__exit__() now calls subclasses' close() method.
3666
3667- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003668
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003669- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003670 issue 215555 for a discussion.
3671
Eric Smitha73fbe72008-02-23 03:09:44 +00003672- Added the future_builtins module, which contains hex() and oct().
3673 These are the PEP 3127 version of these functions, designed to be
3674 compatible with the hex() and oct() builtins from Python 3.0. They
3675 differ slightly in their output formats from the existing, unchanged
3676 Python 2.6 builtins. The expected usage of the future_builtins
3677 module is:
3678 from future_builtins import hex, oct
3679
Eric Smith7ef40bf2008-02-20 23:34:22 +00003680- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3681 exponents for exponents with absolute value < 100. Follows C99
3682 standard. This is a change on Windows, which would use 3 digits.
3683 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3684 so that any alterations it does to the resulting string will be
3685 available in stringlib/formatter.h (for float.__format__).
3686
Eric Smith5a3c1352008-02-19 13:21:56 +00003687- Implemented PEP 3101, Advanced String Formatting. This adds a new
3688 builtin format(); a format() method for str and unicode; a
3689 __format__() method to object, str, unicode, int, long, float, and
3690 datetime; the class string.Formatter; and the C API
3691 PyObject_Format().
3692
Georg Brandl3ee81df2008-05-17 18:14:43 +00003693- Fixed several potential crashes, all caused by specially crafted
3694 __del__ methods exploiting objects in temporarily inconsistent
3695 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003696
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003697- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003698 prevent a possible crash: an Abstract Base Class would try to access
3699 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003700
Georg Brandl3ee81df2008-05-17 18:14:43 +00003701- Fixed repr() and str() of complex numbers with infinity or nan as
3702 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003703
Georg Brandl3ee81df2008-05-17 18:14:43 +00003704- Clear all free lists during a gc.collect() of the highest generation
3705 in order to allow pymalloc to free more arenas. Python may give back
3706 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003707
Georg Brandl3ee81df2008-05-17 18:14:43 +00003708- Issue #2045: Fix an infinite recursion triggered when printing a
3709 subclass of collections.defaultdict, if its default_factory is set
3710 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003711
Christian Heimesf75dbef2008-02-08 00:11:31 +00003712- Fixed a minor memory leak in dictobject.c. The content of the free
3713 list was not freed on interpreter shutdown.
3714
Georg Brandl3ee81df2008-05-17 18:14:43 +00003715- Limit free list of method and builtin function objects to 256
3716 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003717
Georg Brandl3ee81df2008-05-17 18:14:43 +00003718- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3719 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003720 to compact the internal free lists of pre-allocted ints and floats.
3721
Georg Brandl3ee81df2008-05-17 18:14:43 +00003722- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3723 calls. Python expected the return type int but the fork familie
3724 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003725
Georg Brandl3ee81df2008-05-17 18:14:43 +00003726- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3727 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003728
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3730 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003731
Georg Brandl3ee81df2008-05-17 18:14:43 +00003732- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3733 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003734
Georg Brandl3ee81df2008-05-17 18:14:43 +00003735- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3736 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003737
Georg Brandl3ee81df2008-05-17 18:14:43 +00003738- Patch #1473257: generator objects gain a gi_code attribute. This is
3739 the same object as the func_code attribute of the function that
3740 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003741
Georg Brandl3ee81df2008-05-17 18:14:43 +00003742- Issue #1920: "while 0" statements were completely removed by the
3743 compiler, even in the presence of an "else" clause, which is
3744 supposed to be run when the condition is false. Now the compiler
3745 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003746
Guido van Rossumeead05f2008-01-24 18:21:02 +00003747- A few crashers fixed: weakref_in_del.py (issue #1377858);
3748 loosing_dict_ref.py (issue #1303614, test67.py);
3749 borrowed_ref_[34].py (not in tracker).
3750
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003751- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003752 suppressed while an extension is loaded by calling SetErrorMode in
3753 dynload_win.c. The error is still reported properly.
3754
Georg Brandl3ee81df2008-05-17 18:14:43 +00003755- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003756 several extension methods and modules do not work without unicode
3757 support.
3758
Georg Brandl26543b12008-01-21 18:36:51 +00003759- Issue #1882: when compiling code from a string, encoding cookies in the
3760 second line of code were not always recognized correctly.
3761
Georg Brandl14404b62008-01-19 19:27:05 +00003762- Issue #1679: "0x" was taken as a valid integer literal.
3763
Georg Brandl6caad7d2008-01-26 14:19:22 +00003764- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003765 added.
3766
Christian Heimesc94e2b52008-01-14 04:13:37 +00003767- sys.float_info / PyFloat_GetInfo: The floating point information
3768 object was converted from a dict to a specialized structseq object.
3769
Georg Brandl3ee81df2008-05-17 18:14:43 +00003770- Patch #1816: Added sys.flags structseq. It exposes the status of
3771 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003772
Georg Brandl3ee81df2008-05-17 18:14:43 +00003773- Objects/structseq.c: Implemented new structseq representation. The
3774 patch makes structseqs (e.g. the return value of os.stat) more
3775 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003776
Georg Brandl3ee81df2008-05-17 18:14:43 +00003777- Patch #1700288: added a type attribute cache that caches method
3778 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003779
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003780- Bug #1776: __import__() no longer accepts filenames on any platform.
3781 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003782
Georg Brandlaed6c662008-01-07 17:25:53 +00003783- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3784
Georg Brandl3ee81df2008-05-17 18:14:43 +00003785- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3786 envvar and sys.dont_write_bytecode attribute. All these can be set
3787 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003788
Georg Brandl3ee81df2008-05-17 18:14:43 +00003789- Improve some exception messages when Windows fails to load an
3790 extension module. Now we get for example '%1 is not a valid Win32
3791 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003792
Georg Brandl3ee81df2008-05-17 18:14:43 +00003793- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003795- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3796 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003797
Christian Heimes0a8143f2007-12-18 23:22:54 +00003798- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003799 and INF. float("nan"), float("inf") and float("-inf") now work on
3800 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003801
Georg Brandl3ee81df2008-05-17 18:14:43 +00003802- Compiler now generates simpler and faster code for dictionary
3803 literals. The oparg for BUILD_MAP now indicates an estimated
3804 dictionary size. There is a new opcode, STORE_MAP, for adding
3805 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003806
Georg Brandl3ee81df2008-05-17 18:14:43 +00003807- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003809- Issue #1620: New property decorator syntax was modifying the
3810 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003811
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812- Issue #1538: Avoid copying string in split/rsplit if the split char
3813 is not found.

3823 running, and if the deallocation of its frames somehow calls the
3824 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003825

3835 file can now be directly executed by passing their name to the
3836 interpreter. The directory/zipfile is automatically inserted as the
3837 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003838
Georg Brandl3ee81df2008-05-17 18:14:43 +00003839- Issue #1265: Fix a problem with sys.settrace, if the tracing
3840 function uses a generator expression when at the same time the
3841 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003842
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003843- sets and frozensets now have an isdisjoint() method.
3844
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003845- optimize the performance of builtin.sum().
3846
Neal Norwitz44f326e2007-10-05 05:29:17 +00003847- Fix warnings found by the new version of the Coverity checker.
3848
Georg Brandl3ee81df2008-05-17 18:14:43 +00003849- The enumerate() builtin function is no longer bounded to sequences
3850 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3851 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003852
Georg Brandl3ee81df2008-05-17 18:14:43 +00003853- Issue #1686386: Tuple's tp_repr did not take into account the
3854 possibility of having a self-referential tuple, which is possible
3855 from C code. Nor did object's tp_str consider that a type's tp_str
3856 could do something that could lead to an inifinite recursion.
3857 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3858 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003859
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860- Issue #1164: It was possible to trigger deadlock when using the
3861 'print' statement to write to a file since the GIL was not released
3862 as needed. Now PyObject_Print() does the right thing along with
3863 various tp_print implementations of the built-in types and those in
3864 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003865
Georg Brandl3ee81df2008-05-17 18:14:43 +00003866- Issue #1147: Exceptions were directly allowing string exceptions in
3867 their throw() method even though string exceptions no longer
3868 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003869
Georg Brandl3ee81df2008-05-17 18:14:43 +00003870- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003873- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003874 PyObject_Call() never calling back out to Python code to trigger
3875 recursion depth updates/checks. Required the creation of a static
3876 RuntimeError instance in case normalizing an exception put the
3877 recursion check value past its limit. Fixes crashers
3878 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003879

Neal Norwitz0ac60192007-05-27 04:08:54 +00003893- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003894 __*__ attributes. (Some already existed, e.g., __doc__ and
3895 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003896
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003897- Add -3 option to the interpreter to warn about features that are
3898 deprecated and will be changed/removed in Python 3.0.
3899

3901 calls.
3902
Collin Winter62903052007-05-18 23:11:24 +00003903- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003904 "except E as target:". This is to provide forwards compatibility
3905 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003906
Brett Cannon229cee22007-05-05 01:34:02 +00003907- Deprecate BaseException.message as per PEP 352.
3908
Georg Brandl3ee81df2008-05-17 18:14:43 +00003909- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003910 inherited from a builtin base.
3911
Vinay Sajip8549ce32007-05-06 17:53:37 +00003912- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003913 setting a plain string, ie don't expand to single letter identifiers.
3914
Raymond Hettinger13936692007-04-11 18:40:58 +00003915- Request #1191699: Slices can now be pickled.
3916
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003917- Request #1193128: str.translate() now allows a None argument for
3918 translations that only remove characters without re-mapping the
3919 remaining characters.
3920
Georg Brandl5cb76c12007-03-21 09:00:39 +00003921- Patch #1682205: a TypeError while unpacking an iterable is no longer

3925
Guido van Rossum143b5642007-03-23 04:58:42 +00003926- Bug #1683368: The object.__init__() and object.__new__() methods are
3927 now stricter in rejecting excess arguments. The only time when
3928 either allows excess arguments is when it is not overridden and the
3929 other one is. For backwards compatibility, when both are
3930 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003931 warning later). Also, type.__init__() insists on the same signature
3932 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003933
Georg Brandl3ee81df2008-05-17 18:14:43 +00003934- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3935 object to complex using its __complex__() method before falling back
3936 to the __float__() method. Therefore, the functions in the cmath
3937 module now can operate on objects that define a __complex__()
3938 method.

3942 same slot names.

3955
Georg Brandl7b9c5552007-03-12 14:30:05 +00003956- Bug #1678647: write a newline after printing an exception in any
3957 case, even when converting the value to a string failed.
3958
Georg Brandl871f1bc2007-03-12 13:17:36 +00003959- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003960 its argument, if it exists. If not, it will work like before. This
3961 allows customizing the output of dir() in the presence of a
3962 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003963
Collin Winter276887b2007-03-12 16:11:39 +00003964- Patch #922167: Python no longer segfaults when faced with infinitely
3965 self-recursive reload() calls (as reported by bug #742342).
3966
Georg Brandl3ee81df2008-05-17 18:14:43 +00003967- Patch #1675981: remove unreachable code from ``type.__new__()``

3971 parthensized forms. This means complex(repr(x)) now works instead of
3972 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003973
Georg Brandlaa2321b2007-03-07 00:40:28 +00003974- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003975 makes the filenames the warning module prints much more sensible
3976 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003977
Georg Brandl49aafc92007-03-07 00:34:46 +00003978- Variant of patch #697613: don't exit the interpreter on a SystemExit
3979 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003980 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00003989- Patch #1674228: when assigning a slice (old-style), check for the
3990 sq_ass_slice instead of the sq_slice slot.
3991
Georg Brandl3ee81df2008-05-17 18:14:43 +00003992- When printing an unraisable error, don't print exceptions. before
3993 the name. This duplicates the behavior whening normally printing
3994 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003995

4003 created a weakref on itself during a __del__ call for new-style
4004 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004527 AttributeError instead of an IOError when the server's response

4619 TestCase and TestSuite subclasses (not instances) are no longer
4620 accepted in TestSuite.addTest(). This should cause no

4902 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004903
Georg Brandl3ee81df2008-05-17 18:14:43 +00004904- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4905 with RFC 3207 and forgets any knowledge obtained from the server not
4906 obtained from the TLS negotiation itself. Patch contributed by Bill
4907 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004908
Georg Brandl3ee81df2008-05-17 18:14:43 +00004909- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004910 that the SMTP.starttls() caller no longer needs to call ehlo()
4911 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004912 does not claim to support starttls. Adds the
4913 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4994 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4995 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005012 time so that opening a database previously created with the DB_DUP
5013 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5014 opens. Specifically: dictionary assignment to a DB object will
5015 replace all values for a given key when the database allows
5016 duplicate values. DB users should use DB.put(k, v) when they want
5017 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005018

5024 characters with ASCII value less than 32. Also, it correctly quotes
5025 dots only if they occur on a single line, as opposed to the previous
5026 behavior of quoting dots if they are the second character of any
5027 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005028

5365 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005366
5367- Patch #1720595: add T_BOOL to the range of structmember types.
5368
5369- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5370 ``PyFloat_GetInfo()`` to the float API.
5371
Georg Brandl3ee81df2008-05-17 18:14:43 +00005372- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5373 of w# format code incorrectly truncated the length to an int, even
5374 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5375 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005376
Georg Brandl3ee81df2008-05-17 18:14:43 +00005377- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5378 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005380- PEP 3123: Provide forward compatibility with Python 3.0, while
5381 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5382 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005383
Georg Brandl3ee81df2008-05-17 18:14:43 +00005384- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5385 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005386
5387- Patch #1733960: Allow T_LONGLONG to accept ints.
5388
5389- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5390
Christian Heimes000a0742008-01-03 22:16:32 +00005391- Added a new API function ``PyImport_ImportModuleNoBlock``.

Georg Brandl6caad7d2008-01-26 14:19:22 +00005393- Bug #1637022: Prefix AST symbols with _Py_.
5394
5395- Fix some leftovers from the conversion from int to Py_ssize_t
5396 (relevant to strings and sequences of more than 2**31 items).
5397
5398- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5399 outside of pystate.c and should not be necessary.
5400
Georg Brandl3ee81df2008-05-17 18:14:43 +00005401- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5402 absolute imports. In earlier versions they might have used relative
5403 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005404
Georg Brandl3ee81df2008-05-17 18:14:43 +00005405- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5406 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005407
Georg Brandl3ee81df2008-05-17 18:14:43 +00005408- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5409 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005415- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5416 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5417 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5418 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005433- Removed the macfs module. It had been deprecated since Python 2.5.
5434 This lead to the deprecation of macostools.touched() as it relied
5435 solely on macfs and was a no-op under OS X.
