244 encoded string for them. This ensure that the upload and register commands
245 send the right values to PyPI without any error.
246
R. David Murrayed44dfa2010-01-16 05:15:17 +0000247- Issue #1670765: Prevent email.generator.Generator from re-wrapping

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000317What's New in Python 2.7 alpha 2?
318=================================
319
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000320*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000321
322Core and Builtins
323-----------------
324
Benjamin Petersonecdae192010-01-04 00:43:01 +0000325- The __complex__ method is now looked up on the class of instances to make it
326 consistent with other special methods.
327
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000328- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
329 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
330
Mark Dickinson1b34d252010-01-01 17:27:30 +0000331- Issue #5080: A number of functions and methods previously produced a
332 DeprecationWarning when passed a float argument where an integer was
333 expected. These functions and methods now raise TypeError instead.
334 The majority of the effects of this change are in the extension
335 modules, but some core functions and methods are affected: notably
336 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
337 methods.
338
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000339- Issue #7604: Deleting an unset slotted attribute did not raise an
340 AttributeError.
341
Mark Dickinson99d652e2009-12-30 12:12:23 +0000342- Issue #7534: Fix handling of IEEE specials (infinities, nans,
343 negative zero) in ** operator. The behaviour now conforms to that
344 described in C99 Annex F.
345
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000346- Issue #7579: the msvcrt module now has docstrings for all its functions.
347
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000348- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
349 used to drop the time part of the result.
350
Mark Dickinson46572832009-12-27 14:55:57 +0000351- Issue #1811: improve accuracy and cross-platform consistency for
352 true division of integers: the result of a/b is now correctly
353 rounded for ints a and b (at least on IEEE 754 platforms), and in
354 particular does not depend on the internal representation of a long.
355
Ezio Melottif84caf42009-12-24 22:25:17 +0000356- Issue #6108: unicode(exception) and str(exception) should return the same
357 message when only __str__ (and not __unicode__) is overridden in the subclass.
358
Ronald Oussoren92919a62009-12-24 13:30:58 +0000359- Issue #6834: replace the implementation for the 'python' and 'pythonw'
360 executables on OSX.
361
362 These executables now work properly with the arch(1) command:
363 ``arch -ppc python`` will start a universal binary version of python
364 in PPC mode (unlike previous releases).
365
R. David Murray0a0a1a82009-12-14 16:28:26 +0000366- Issue #1680159: unicode coercion during an 'in' operation no longer masks
367 the underlying error when the coercion fails for the left hand operand.
368
Benjamin Peterson4895af42009-12-13 16:36:53 +0000369- Issue #7491: Metaclass's __cmp__ method was ignored.
370
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000371- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +0000372 in the middle of populating a tuple. Patch by Florent Xicluna.
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000373

377
Jesse Noller654ade32010-01-27 03:05:57 +0000378- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
379 allowing for a maximum number of tasks within the pool to be completed by
380 the worker before that worker is terminated, and a new one created to
381 replace it.
382
Tarek Ziadéc25417f2010-01-08 23:42:23 +0000383- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes
384 gcc when it has a fully qualified configuration prefix. Initial patch
385 by Arfrever.
386
Antoine Pitrou80157252010-01-08 19:20:17 +0000387- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
388 renaming of `cPickle` to `pickle`. The warning was annoying since there's
389 no alternative to cPickle if you care about performance. Patch by Florent
390 Xicluna.
391
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000392- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

Antoine Pitroub9d49632010-01-04 23:22:44 +0000395- Issue #7092: Fix the DeprecationWarnings emitted by the standard library
396 when using the -3 flag. Patch by Florent Xicluna.
397
Antoine Pitrou673ddf92010-01-03 22:29:56 +0000398- Issue #7471: Improve the performance of GzipFile's buffering mechanism,
399 and make it implement the `io.BufferedIOBase` ABC to allow for further
400 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
401
402- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000403 parameter to allow specifying where your connections come from.
404
Gregory P. Smith79a3eb12010-01-03 01:29:44 +0000405- socket.create_connection now accepts an optional source_address parameter.
406
Ezio Melotti569e61f2009-12-30 06:14:51 +0000407- Issue #5511: now zipfile.ZipFile can be used as a context manager.
408 Initial patch by Brian Curtin.
409
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +0000410- Distutils now correctly identifies the build architecture as "x86_64"
Ezio Melotti569e61f2009-12-30 06:14:51 +0000411 when building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +0000412
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000413- Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest

415
Tarek Ziadé2421d562009-12-20 23:23:34 +0000416- Issue #7552: Removed line feed in the base64 Authorization header in
417 the Distutils upload command to avoid an error when PyPI reads it.
418 This occurs on long passwords. Initial patch by JP St. Pierre.
419
420- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000421 Patch by Tatsuhiro Tsujikawa.
422
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000423- Issue #7349: Make methods of file objects in the io module accept None as an
424 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
425 the same as passing no argument.
426
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000427- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
428 like other file objects.
429
Lars Gustäbel92ca7562009-12-13 11:32:27 +0000430- Issue #7357: tarfile no longer suppresses fatal extraction errors by
431 default.
432
Vinay Sajip5cc4e2a2009-12-11 09:16:01 +0000433- Issue #7470: logging: fix bug in Unicode encoding fallback.
434
R. David Murray93321f32009-12-09 15:15:31 +0000435- Issue #5949: fixed IMAP4_SSL hang when the IMAP server response is
436 missing proper end-of-line termination.
437
Tarek Ziadé2421d562009-12-20 23:23:34 +0000438- Issue #7457: added a read_pkg_file method to
Tarek Ziadéa939ecd2009-12-08 08:56:49 +0000439 distutils.dist.DistributionMetadata.
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000440
Gregory P. Smithfe32d302010-01-02 22:42:50 +0000441- Issue #3745: Undo the 2.7a1 change to have hashlib to reject unicode and
Georg Brandl92c58ae2010-01-02 22:55:55 +0000442 non buffer-api supporting objects as input. That behavior is for 3.x only.

448 analogous to PyLong_AsLongAndOverflow.
449
Mark Dickinson1b34d252010-01-01 17:27:30 +0000450- Issue #5080: The argument parsing functions PyArg_ParseTuple,
451 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
452 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
453 arguments for integer format codes (other than 'L'): previously an
454 attempt to pass a float resulted in a DeprecationWarning; now it
455 gives a TypeError. For the 'L' format code (which previously had no
456 warning) there is now a DeprecationWarning.
457
Georg Brandl740cdc32009-12-28 08:34:58 +0000458- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

Benjamin Peterson2c196742009-12-31 03:17:18 +0000468- Issue #7609: Add a --with-system-expat option that causes the system's expat
469 library to be used for the pyexpat module instead of the one included with
470 Python.
471
Benjamin Peterson500ce232009-12-30 02:58:50 +0000472- Issue #7589: Only build the nis module when the correct header files are

500
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000501- Issue #7419: setlocale() could crash the interpreter on Windows when called
502 with invalid values.
503
Eric Smithc4ab8332009-11-29 17:40:57 +0000504- Issue #3382: 'F' formatting for float and complex now convert the
505 result to upper case. This only affects 'inf' and 'nan', since 'f'
506 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000507
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000508- Remove switch from "%f" formatting to "%g" formatting for floats
509 larger than 1e50 in absolute value.
510
Mark Dickinson18cfada2009-11-23 18:46:41 +0000511- Remove restrictions on precision when formatting floats. E.g.,
512 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
513 requested 120 significant digits instead.
514
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000515- Add Py3k warnings for parameter names in parenthesis.
516
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000517- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000518
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000519- Issue #7085: Fix crash when importing some extensions in a thread
520 on MacOSX 10.6.
521
Mark Dickinsonb678de82009-11-19 18:41:49 +0000522- Issue #7117: repr(x) for a float x returns a result based on the
523 shortest decimal string that's guaranteed to round back to x under
524 correct rounding (with round-half-to-even rounding mode).
525 Previously it gave a string based on rounding x to 17 decimal digits.
526 repr(x) for a complex number behaves similarly. On platforms where
527 the correctly-rounded strtod and dtoa code is not supported (see below),
528 repr is unchanged.
529
530- Issue #7117: On almost all platforms: float-to-string and
531 string-to-float conversions within Python are now correctly rounded.
532 Places these conversions occur include: str for floats and complex
533 numbers; the float and complex constructors; old-style and new-style
534 numeric formatting; serialization and deserialization of floats and
535 complex numbers using marshal, pickle and json; parsing of float and
536 imaginary literals in Python code; Decimal-to-float conversion.
537
538 The conversions use a Python-adapted version of David Gay's
539 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
540 functions. This code is supported on Windows, and on Unix-like
541 platforms using gcc, icc or suncc as the C compiler. There may be a
542 small number of platforms on which correct operation of this code
543 cannot be guaranteed, so the code is not used: notably, this applies
544 to platforms where the C double format is not IEEE 754 binary64, and
545 to platforms on x86 hardware where the x87 FPU is set to 64-bit
546 precision and Python's configure script is unable to determine how
547 to change the FPU precision. On these platforms conversions use the
548 platform strtod and dtoa, as before.
549
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000550- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000551 now uses the correctly-rounded string <-> float conversions
552 described above (when available), and so produces correctly rounded
553 results that will display nicely under the float repr. There are
554 two related small changes: (1) round now accepts any class with an
555 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000556 floats for the second argument), and (2) an excessively large second
557 integer argument (e.g., round(1.234, 10**100)) no longer raises an
558 exception.
559
Philip Jenveyfab8be22009-11-17 02:42:26 +0000560- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
561
Benjamin Petersone36199b2009-11-12 23:39:44 +0000562- Fix several issues with compile(). The input can now contain Windows and Mac

566 unicode string.
567
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000568- Issue #7244: itertools.izip_longest() no longer ignores exceptions

588 Patch by Christopher Tur Lesniewski-Laas.
589
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000590- Issue #7084: Fix a (very unlikely) crash when printing a list from one

606 of producing internally inconsistent Python longs.
607
Philip Jenveydbf3b252009-09-29 04:32:44 +0000608- Issue #6990: Fix threading.local subclasses leaving old state around
609 after a reference cycle GC which could be recycled by new locals.

703 was locale aware; and (3) the interpretation of fromhex('-nan')
704 didn't match that of float('-nan').
705
Eric Smitha985a3a2009-05-05 18:26:08 +0000706- Issue #5920: For float.__format__, change the behavior with the
707 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
708 to be like 'g' but with at least one decimal point and with a
709 default precision of 12. Previously, the behavior the same but with
710 a default precision of 6. This more closely matches str(), and
711 reduces surprises when adding alignment flags to the empty
712 presentation type. This also affects the new complex.__format__ in
713 the same way.
714

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

787 2**15 for the internal representation of integers, for performance
788 reasons. Base 2**30 is enabled by default on 64-bit machines. Add

815 on a 64-bit system.
816
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000817- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

824
Georg Brandl29c6a282009-04-05 20:23:13 +0000825- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000826 were suppressing all exceptions. These include list(), filter(), map(),

902 str instances. On a typical machine this saves 3 bytes of memory
903 (on average) per string allocation.
904
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000905- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
906 interpreter to abort ("Fatal Python error: Could not reset the stack!")
907 instead of throwing a MemoryError.
908
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000909- Issue #3689: The list reversed iterator now supports __length_hint__

911
Benjamin Petersonc078f922008-11-21 22:27:24 +0000912- Issue #4367: Python would segfault during compiling when the unicodedata

914
Vinay Sajip213faca2008-12-03 23:22:58 +0000915- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000916 method on file objects with closefd=False. The file descriptor is still
917 kept open but the file object behaves like a closed file. The ``FileIO``
918 object also got a new readonly attribute ``closefd``.
919
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000920- Issue #4348: Some bytearray methods returned that didn't cause any change to

937
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000938- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000939 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000941- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
942 returned a path longer than MAX_PATH. (But It's doubtful this code path is
943 really executed because I cannot move to such directory on win2k)
944
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000945- Issue #4069: When set.remove(element) is used with a set element, the element
946 is temporarily replaced with an equivalent frozenset. But the eventual
947 KeyError would always report the empty frozenset([]) as the missing key. Now
948 it correctly refers to the initial element.

966 returned them on 64bit platforms.
967
Walter Dörwalded960ac2009-05-03 22:36:33 +0000968- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
969 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
970 step. This avoids problems with counting UTF-8 bytes that ignores the effect
971 of using the replace error handler in PyUnicode_DecodeUTF8().
972
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000973- Issue #3739: The unicode-internal encoder now reports the number of characters
974 consumed like any other encoder (instead of the number of bytes).
975
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000976- Issue #2422: When compiled with the ``--with-valgrind`` option, the
977 pymalloc allocator will be automatically disabled when running under
978 Valgrind. This gives improved memory leak detection when running
979 under Valgrind, while taking advantage of pymalloc at other times.

2216 leak-chasing test runs give sensible results. The previous method of

2360
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002361- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2362 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2363 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2364 ``printf`` function, whereas PyString_FromFormat has an independent
2365 implementation and uses "%zd" on all platforms for size_t values.
2366 This makes a difference on win64, where ``printf`` needs "%Id" to display
2367 64bit values.

2373 object; previously an int would be returned for small values. the __long__
2374 method is allowed to return either an int or a long, but the behaviour of
2375 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002377- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002383 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002384 was correctly parsed but parsing of subsequent arguments failed.
2385
Vinay Sajip35e3b032008-09-01 14:33:59 +00002386- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002387 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2388 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2389 when given a tuple of classes as second argument, were looking up
2390 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2391 type object.

Neal Norwitz18aa3882008-08-24 05:04:52 +00002393- Fix crashes on memory allocation failure found with failmalloc.

2536-----------------
2537
Guido van Rossumf8402962008-08-20 15:01:50 +00002538- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2539 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2540 extensions do not automatically benefit from the class attribute
2541 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2542 to their tp_flags field if they care. This is a backwards
2543 compatibility feature; in 3.0, all types will use the cache by
2544 default.
2545
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002546- Keyword arguments can now follow starred arguments. (``f(a, *args,

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002552- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2553 by denying s# to parse objects that have a releasebuffer procedure,

Georg Brandl1e13ea92008-08-11 09:07:59 +00002556- Issue #3537: Fix an assertion failure when an empty but presized dict
2557 object was stored in the freelist.
2558
Mark Dickinsonb6467572008-08-04 21:30:09 +00002559- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2560 ValueError consistently across platforms.
2561
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002562- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2563 (64bit Unix, for example), unichr() would truncate its argument and return
2564 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2565
Neal Norwitze7d8be82008-07-31 17:17:14 +00002566- Apply security patches from Apple.
2567
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002568- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2569 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2570
Antoine Pitrou92f82162008-07-25 22:22:08 +00002571- Issue #1819: function calls with several named parameters are now on
2572 average 35% faster (as measured by pybench).
2573
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002574- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2575 the python debugger steps into a class statement: the free variables (local
2576 variables defined in an outer scope) would be deleted from the outer scope.
2577
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002578- Issue #2620: Overflow checking when allocating or reallocating memory
2579 was not always being done properly in some python types and extension
2580 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2581 all been updated to perform better checks and places in the code that
2582 would previously leak memory on the error path when such an allocation
2583 failed have been fixed.

2589
Benjamin Petersone977ad42008-08-20 01:42:01 +00002590- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2591 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2592
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002593- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2594 version reported by these tools does not necessarily follow the python
2595 version numbering scheme, so the module is less strict when parsing it.
2596
Nick Coghlanf70385a2008-08-18 12:42:46 +00002597- Issue #2235: Added Py3k warnings for types which will become unhashable
2598 under the stricter __hash__ inheritance rules in 3.0. Several types
2599 which did not meet the rules for hash invariants and were already
2600 unhashable in 3.0 have now been explicitly flagged as unhashable in
2601 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2602 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2603
Brett Cannon88f801d2008-08-18 00:46:22 +00002604- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2605 imported into the module but exposed as part of the module's API.
2606
Brett Cannon7b96f072008-08-18 00:41:11 +00002607- Remove an unneeded import of abc.ABCMeta from 'inspect'.

2612
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002613- Issue #3575: Incremental decoder's decode function now takes bytearray
2614 by using 's*' instead of 't#'.
2615
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002616- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002617 fails unicode conversion on 2nd parameter. (windows only)

Facundo Batistaeb90b782008-08-16 14:44:07 +00002625- Issue #2776: fixed small issue when handling an URL with double slash
2626 after a 302 response in the case of not going through a proxy.
2627
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002628- Issue #2676: in the email package, content-type parsing was hanging on
2629 pathological input because of quadratic or exponential behaviour of a
2630 regular expression.
2631
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002632- Issue #3476: binary buffered reading through the new "io" library is now
2633 thread-safe.
2634
Brett Cannonbf3157b2008-08-14 05:00:03 +00002635- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2636 since mimetools itself is deprecated. Because modules are cached, all
2637 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2638
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002639- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002641- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2642 menu entries were not deleted.
2643
Brett Cannon83e81842008-08-09 23:30:55 +00002644- Copied the implementation of reduce() to _functools.reduce() to have a
2645 version that did not raise a DeprecationWarning under -3.
2646
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002647- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2648 a MemoryError rather than silently stop the iteration.
2649
Guido van Rossum59ce9012008-08-09 14:55:34 +00002650- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2651 to _sre.compile() will now be rejected. This should not affect anybody
2652 since the re.compile() function never generates invalid re-bytecode.
2653
Skip Montanaroa032bf42008-08-08 22:52:51 +00002654- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2655 upon first access it can be automatically initialized from the csv file if
2656 it wasn't initialized during instantiation.
2657
Brett Cannon3aa2a492008-08-06 22:28:09 +00002658- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2659 the reload() built-in has been removed.
2660
Brett Cannon7e30b672008-08-04 21:52:25 +00002661- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002662 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2670 raised an AttributeError.
2671
Benjamin Peterson01a24322008-07-28 23:35:27 +00002672- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002673 asking for a specific length. This problem only affected files opened
2674 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002675

2698
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002699- Issue #3394: zipfile.writestr sets external attributes when passed a
2700 file name rather than a ZipInfo instance, so files are extracted with
2701 mode 0600 rather than 000 under Unix.
2702
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002703- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2704 argument in python 2.5, this broke code that subclassed Popen to include its
2705 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2714
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002715- Issue #2235: the C API function PyObject_HashNotImplemented and its
2716 interaction with the tp_hash slot (added in 2.6b2) are now documented
2717
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002718- Issue #643841: The language reference now provides more detailed
2719 coverage of the lookup process for special methods. The disclaimers
2720 regarding lack of coverage of new-style classes have also been
2721 removed, since the coverage is now fairly reasonable.

2725================================
2726
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002727*Release date: 17-Jul-2008*
2728
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002729Core and Builtins
2730-----------------
2731
Georg Brandl3e483f62008-07-16 22:57:41 +00002732- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2733 its methods now allow for items objects that can be converted to
2734 an integer using operator.index().
2735
Mark Dickinson64b7e502008-07-16 09:40:03 +00002736- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2737 produced a ValueError instead of giving the correct float.
2738
Eric Smitha5fa5a22008-07-16 00:11:49 +00002739- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2740 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2741
Mark Dickinson7103aa42008-07-15 19:08:33 +00002742- Issue #3008: the float type has a new instance method 'float.hex'
2743 and a new class method 'float.fromhex' to convert floating-point
2744 numbers to and from hexadecimal strings, respectively.
2745
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002746- Issue #2235: __hash__ is once again inherited by default. To allow
2747 collections.Hashable to remain meaningful in the presence of the
2748 default hash implementation (object.__hash__), it is now possible
2749 to explicit block inheritance of hash by setting __hash__=None at
2750 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2751 level.
2752
Nick Coghlanb028f502008-07-13 14:52:36 +00002753- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2754 the parent module cannot be found while performing an absolute import.
2755 This means that an incorrectly defined __package__ attribute will
2756 now only prevent relative imports in that module rather than causing
2757 all imports from that module to fail.
2758
Nick Coghlan14ff9942008-07-08 14:21:42 +00002759- Issue #2517: Allow unicode messages in Exceptions again by correctly
2760 bypassing the instance dictionary when looking up __unicode__ on
2761 new-style classes.
2762
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002763- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2764 set to a custom object whose write() method happens to install
2765 another file in sys.stdout.
2766
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002767- Issue #3088: Corrected a race condition in classes derived from
2768 threading.local: the first member set by a thread could be saved in
2769 another thread's dictionary.
2770
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002771- Issue #3004: Minor change to slice.indices(): the start and stop
2772 arguments are now treated identically, making the behaviour easier
2773 to describe and understand. For example, slice(None, -10,
2774 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2775 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2776 10, -1).
2777
Georg Brandl278fc502008-07-19 12:46:12 +00002778- Issue #3219: Calling a function with repeated keyword arguments,
2779 f(a=2, a=23), would not cause a syntax error. This was a regression
2780 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002781
Georg Brandl278fc502008-07-19 12:46:12 +00002782- Issue #2862: Make int and float freelist management consistent with
2783 other freelists. Changes their CompactFreeList apis into
2784 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002785

2787-------
2788
Thomas Heller57adf222008-08-14 19:10:48 +00002789- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2790 api functions without holding the GIL, which could lead to a fatal
2791 error when they failed.
2792
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002793- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2802 ForkingPickler.register() to resolve conflict with ctypes.
2803
Vinay Sajip51e65192008-07-18 09:01:10 +00002804- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002805
Thomas Heller880f5292008-07-15 19:39:38 +00002806- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2807 a valid dlerror() message.
2808
Thomas Heller2bad6572008-07-15 17:19:50 +00002809- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2810 incomplete structure was created.
2811
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002812- Issue #3339: dummy_thread.acquire() should not return None.
2813
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002814- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2815
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002816- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002817
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002818- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2819 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002820 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002821 content-length. The problem had been corrected in the 2.4 branch, but never
2822 merged into trunk.
2823
Georg Brandle78fbcc2008-07-05 10:13:36 +00002824- Issue #2663: add filtering capability to shutil.copytree().

2829
2830- Issue #1746: Correct handling of zipfile archive comments (previously
2831 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002832 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002833
Vinay Sajip51e65192008-07-18 09:01:10 +00002834- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002835 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002836
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002837- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00003230 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003231
3232 This is controlled by the configure argument ``--with-universal-archs``:
3233
3234 - ``--with-universal-archs=all``: install 4-way universal
3235
3236 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3237
3238 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3239
3240 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003292- Issue #1631171: Re-implement the 'warnings' module in C (the
3293 original Python code has been kept as backup). This will allow for
3294 using the 'warning's machinery in such places as the parser where
3295 use of pure Python code is not possible. Both the ``showarning()``
3296 and ``formatwarning()`` gain an optional 'line' argument which is
3297 not called by default for backwards-compatibility reasons. Setting
3298 ``warnings.showwarning()`` to an implementation that lacks support
3299 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003362- Issue #2550: The approach used by client/server code for obtaining
3363 ports to listen on in network-oriented tests has been refined in an
3364 effort to facilitate running multiple instances of the entire
3365 regression test suite in parallel without issue.
3366 test_support.bind_port() has been fixed such that it will always
3367 return a unique port -- which wasn't always the case with the
3368 previous implementation, especially if socket options had been set
3369 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3370 new implementation of bind_port() will actually raise an exception
3371 if it is passed an AF_INET/SOCK_STREAM socket with either the
3372 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3373 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3374 the socket it's been passed. This currently only applies to
3375 Windows. This option prevents any other sockets from binding to the
3376 host/port we've bound to, thus removing the possibility of the
3377 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3378 when a second SOCK_STREAM socket binds and accepts to a host/port
3379 that's already been bound by another socket. The optional preferred
3380 port parameter to bind_port() has been removed. Under no
3381 circumstances should tests be hard coding ports!
3382
3383 test_support.find_unused_port() has also been introduced, which will
3384 pass a temporary socket object to bind_port() in order to obtain an
3385 unused port. The temporary socket object is then closed and
3386 deleted, and the port is returned. This method should only be used
3387 for obtaining an unused port in order to pass to an external program
3388 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3389 a parameter to a server-oriented class that doesn't give you direct
3390 access to the underlying socket used.
3391
3392 Finally, test_support.HOST has been introduced, which should be used
3393 for the host argument of any relevant socket calls (i.e. bind and
3394 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003395
3396 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003397 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003398 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3399 test_asynchat and test_socket_ssl.
3400
Georg Brandl3ee81df2008-05-17 18:14:43 +00003401 It is now possible for multiple instances of the regression test
3402 suite to run in parallel without issue.

3668Core and builtins
3669-----------------
3670
Fred Drakea8ee94b2008-03-01 02:45:07 +00003671- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003672 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003673
Georg Brandlad61bc82008-02-23 15:11:18 +00003674- Issue #2067: file.__exit__() now calls subclasses' close() method.
3675
3676- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003677
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003678- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003679 issue 215555 for a discussion.
3680
Eric Smitha73fbe72008-02-23 03:09:44 +00003681- Added the future_builtins module, which contains hex() and oct().
3682 These are the PEP 3127 version of these functions, designed to be
3683 compatible with the hex() and oct() builtins from Python 3.0. They
3684 differ slightly in their output formats from the existing, unchanged
3685 Python 2.6 builtins. The expected usage of the future_builtins
3686 module is:
3687 from future_builtins import hex, oct
3688
Eric Smith7ef40bf2008-02-20 23:34:22 +00003689- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3690 exponents for exponents with absolute value < 100. Follows C99
3691 standard. This is a change on Windows, which would use 3 digits.
3692 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3693 so that any alterations it does to the resulting string will be
3694 available in stringlib/formatter.h (for float.__format__).
3695
Eric Smith5a3c1352008-02-19 13:21:56 +00003696- Implemented PEP 3101, Advanced String Formatting. This adds a new
3697 builtin format(); a format() method for str and unicode; a
3698 __format__() method to object, str, unicode, int, long, float, and
3699 datetime; the class string.Formatter; and the C API
3700 PyObject_Format().
3701
Georg Brandl3ee81df2008-05-17 18:14:43 +00003702- Fixed several potential crashes, all caused by specially crafted
3703 __del__ methods exploiting objects in temporarily inconsistent
3704 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003705
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003706- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003707 prevent a possible crash: an Abstract Base Class would try to access
3708 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003709
Georg Brandl3ee81df2008-05-17 18:14:43 +00003710- Fixed repr() and str() of complex numbers with infinity or nan as
3711 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003712
Georg Brandl3ee81df2008-05-17 18:14:43 +00003713- Clear all free lists during a gc.collect() of the highest generation
3714 in order to allow pymalloc to free more arenas. Python may give back
3715 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003716
Georg Brandl3ee81df2008-05-17 18:14:43 +00003717- Issue #2045: Fix an infinite recursion triggered when printing a
3718 subclass of collections.defaultdict, if its default_factory is set
3719 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003720
Christian Heimesf75dbef2008-02-08 00:11:31 +00003721- Fixed a minor memory leak in dictobject.c. The content of the free
3722 list was not freed on interpreter shutdown.
3723
Georg Brandl3ee81df2008-05-17 18:14:43 +00003724- Limit free list of method and builtin function objects to 256
3725 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003726
Georg Brandl3ee81df2008-05-17 18:14:43 +00003727- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3728 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003729 to compact the internal free lists of pre-allocted ints and floats.
3730
Georg Brandl3ee81df2008-05-17 18:14:43 +00003731- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3732 calls. Python expected the return type int but the fork familie
3733 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003734
Georg Brandl3ee81df2008-05-17 18:14:43 +00003735- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3736 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003737
Georg Brandl3ee81df2008-05-17 18:14:43 +00003738- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3739 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003740
Georg Brandl3ee81df2008-05-17 18:14:43 +00003741- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3742 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003743
Georg Brandl3ee81df2008-05-17 18:14:43 +00003744- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3745 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003746
Georg Brandl3ee81df2008-05-17 18:14:43 +00003747- Patch #1473257: generator objects gain a gi_code attribute. This is
3748 the same object as the func_code attribute of the function that
3749 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003750
Georg Brandl3ee81df2008-05-17 18:14:43 +00003751- Issue #1920: "while 0" statements were completely removed by the
3752 compiler, even in the presence of an "else" clause, which is
3753 supposed to be run when the condition is false. Now the compiler
3754 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003755
Guido van Rossumeead05f2008-01-24 18:21:02 +00003756- A few crashers fixed: weakref_in_del.py (issue #1377858);
3757 loosing_dict_ref.py (issue #1303614, test67.py);
3758 borrowed_ref_[34].py (not in tracker).
3759
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003760- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003761 suppressed while an extension is loaded by calling SetErrorMode in
3762 dynload_win.c. The error is still reported properly.
3763
Georg Brandl3ee81df2008-05-17 18:14:43 +00003764- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003765 several extension methods and modules do not work without unicode
3766 support.
3767
Georg Brandl26543b12008-01-21 18:36:51 +00003768- Issue #1882: when compiling code from a string, encoding cookies in the
3769 second line of code were not always recognized correctly.
3770
Georg Brandl14404b62008-01-19 19:27:05 +00003771- Issue #1679: "0x" was taken as a valid integer literal.
3772
Georg Brandl6caad7d2008-01-26 14:19:22 +00003773- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003774 added.
3775
Christian Heimesc94e2b52008-01-14 04:13:37 +00003776- sys.float_info / PyFloat_GetInfo: The floating point information
3777 object was converted from a dict to a specialized structseq object.
3778
Georg Brandl3ee81df2008-05-17 18:14:43 +00003779- Patch #1816: Added sys.flags structseq. It exposes the status of
3780 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003781
Georg Brandl3ee81df2008-05-17 18:14:43 +00003782- Objects/structseq.c: Implemented new structseq representation. The
3783 patch makes structseqs (e.g. the return value of os.stat) more
3784 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003785
Georg Brandl3ee81df2008-05-17 18:14:43 +00003786- Patch #1700288: added a type attribute cache that caches method
3787 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003788
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003789- Bug #1776: __import__() no longer accepts filenames on any platform.
3790 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003791
Georg Brandlaed6c662008-01-07 17:25:53 +00003792- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3793
Georg Brandl3ee81df2008-05-17 18:14:43 +00003794- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3795 envvar and sys.dont_write_bytecode attribute. All these can be set
3796 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003797
Georg Brandl3ee81df2008-05-17 18:14:43 +00003798- Improve some exception messages when Windows fails to load an
3799 extension module. Now we get for example '%1 is not a valid Win32
3800 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003801
Georg Brandl3ee81df2008-05-17 18:14:43 +00003802- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003804- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3805 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003806
Christian Heimes0a8143f2007-12-18 23:22:54 +00003807- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003808 and INF. float("nan"), float("inf") and float("-inf") now work on
3809 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003810
Georg Brandl3ee81df2008-05-17 18:14:43 +00003811- Compiler now generates simpler and faster code for dictionary
3812 literals. The oparg for BUILD_MAP now indicates an estimated
3813 dictionary size. There is a new opcode, STORE_MAP, for adding
3814 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003815
Georg Brandl3ee81df2008-05-17 18:14:43 +00003816- Issue #1638: %zd configure test fails on Linux.

3832 running, and if the deallocation of its frames somehow calls the
3833 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003834

3844 file can now be directly executed by passing their name to the
3845 interpreter. The directory/zipfile is automatically inserted as the
3846 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003847
Georg Brandl3ee81df2008-05-17 18:14:43 +00003848- Issue #1265: Fix a problem with sys.settrace, if the tracing
3849 function uses a generator expression when at the same time the
3850 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003851
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003852- sets and frozensets now have an isdisjoint() method.
3853
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003854- optimize the performance of builtin.sum().
3855
Neal Norwitz44f326e2007-10-05 05:29:17 +00003856- Fix warnings found by the new version of the Coverity checker.
3857
Georg Brandl3ee81df2008-05-17 18:14:43 +00003858- The enumerate() builtin function is no longer bounded to sequences
3859 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3860 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003861
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862- Issue #1686386: Tuple's tp_repr did not take into account the
3863 possibility of having a self-referential tuple, which is possible
3864 from C code. Nor did object's tp_str consider that a type's tp_str
3865 could do something that could lead to an inifinite recursion.
3866 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3867 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003868
Georg Brandl3ee81df2008-05-17 18:14:43 +00003869- Issue #1164: It was possible to trigger deadlock when using the
3870 'print' statement to write to a file since the GIL was not released
3871 as needed. Now PyObject_Print() does the right thing along with
3872 various tp_print implementations of the built-in types and those in
3873 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003874
Georg Brandl3ee81df2008-05-17 18:14:43 +00003875- Issue #1147: Exceptions were directly allowing string exceptions in
3876 their throw() method even though string exceptions no longer
3877 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003878
Georg Brandl3ee81df2008-05-17 18:14:43 +00003879- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003882- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003883 PyObject_Call() never calling back out to Python code to trigger
3884 recursion depth updates/checks. Required the creation of a static
3885 RuntimeError instance in case normalizing an exception put the
3886 recursion check value past its limit. Fixes crashers
3887 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003902- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003903 __*__ attributes. (Some already existed, e.g., __doc__ and
3904 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003905
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003906- Add -3 option to the interpreter to warn about features that are
3907 deprecated and will be changed/removed in Python 3.0.
3908

3910 calls.
3911
Collin Winter62903052007-05-18 23:11:24 +00003912- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003913 "except E as target:". This is to provide forwards compatibility
3914 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003915
Brett Cannon229cee22007-05-05 01:34:02 +00003916- Deprecate BaseException.message as per PEP 352.
3917
Georg Brandl3ee81df2008-05-17 18:14:43 +00003918- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003919 inherited from a builtin base.
3920
Vinay Sajip8549ce32007-05-06 17:53:37 +00003921- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003922 setting a plain string, ie don't expand to single letter identifiers.
3923
Raymond Hettinger13936692007-04-11 18:40:58 +00003924- Request #1191699: Slices can now be pickled.
3925
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003926- Request #1193128: str.translate() now allows a None argument for
3927 translations that only remove characters without re-mapping the
3928 remaining characters.
3929
Georg Brandl5cb76c12007-03-21 09:00:39 +00003930- Patch #1682205: a TypeError while unpacking an iterable is no longer
3931 masked by a generic one with the message "unpack non-sequence".
3932
Neal Norwitzaa754b72007-03-21 06:39:48 +00003933- Remove unused file Python/fmod.c.
3934
Guido van Rossum143b5642007-03-23 04:58:42 +00003935- Bug #1683368: The object.__init__() and object.__new__() methods are
3936 now stricter in rejecting excess arguments. The only time when
3937 either allows excess arguments is when it is not overridden and the
3938 other one is. For backwards compatibility, when both are
3939 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003940 warning later). Also, type.__init__() insists on the same signature
3941 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003942
Georg Brandl3ee81df2008-05-17 18:14:43 +00003943- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3944 object to complex using its __complex__() method before falling back
3945 to the __float__() method. Therefore, the functions in the cmath
3946 module now can operate on objects that define a __complex__()
3947 method.

3950 __slots__. The old and the new class are still required to have the
3951 same slot names.

3964
Georg Brandl7b9c5552007-03-12 14:30:05 +00003965- Bug #1678647: write a newline after printing an exception in any
3966 case, even when converting the value to a string failed.
3967
Georg Brandl871f1bc2007-03-12 13:17:36 +00003968- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003969 its argument, if it exists. If not, it will work like before. This
3970 allows customizing the output of dir() in the presence of a
3971 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003972
Collin Winter276887b2007-03-12 16:11:39 +00003973- Patch #922167: Python no longer segfaults when faced with infinitely
3974 self-recursive reload() calls (as reported by bug #742342).
3975
Georg Brandl3ee81df2008-05-17 18:14:43 +00003976- Patch #1675981: remove unreachable code from ``type.__new__()``

3980 parthensized forms. This means complex(repr(x)) now works instead of
3981 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003982
Georg Brandlaa2321b2007-03-07 00:40:28 +00003983- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003984 makes the filenames the warning module prints much more sensible
3985 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003986
Georg Brandl49aafc92007-03-07 00:34:46 +00003987- Variant of patch #697613: don't exit the interpreter on a SystemExit
3988 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003989 variable is given, but break into the interactive interpreter just
3990 like on other exceptions or normal program exit.

3996 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003997
Georg Brandl0fca97a2007-03-05 22:28:08 +00003998- Patch #1674228: when assigning a slice (old-style), check for the
3999 sq_ass_slice instead of the sq_slice slot.
4000
Georg Brandl3ee81df2008-05-17 18:14:43 +00004001- When printing an unraisable error, don't print exceptions. before
4002 the name. This duplicates the behavior whening normally printing
4003 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004004
Georg Brandl3ee81df2008-05-17 18:14:43 +00004005- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00004011- Bug #1377858: Fix the segfaulting of the interpreter when an object
4012 created a weakref on itself during a __del__ call for new-style
4013 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004536 AttributeError instead of an IOError when the server's response
4537 didn't contain a valid HTTP status line.

4626
Georg Brandl3ee81df2008-05-17 18:14:43 +00004627- unittest now verifies more of its assumptions. In particular,
4628 TestCase and TestSuite subclasses (not instances) are no longer
4629 accepted in TestSuite.addTest(). This should cause no
4630 incompatibility since it never made sense with ordinary subclasses

Georg Brandl3ee81df2008-05-17 18:14:43 +00004913- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4914 with RFC 3207 and forgets any knowledge obtained from the server not
4915 obtained from the TLS negotiation itself. Patch contributed by Bill
4916 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004917
Georg Brandl3ee81df2008-05-17 18:14:43 +00004918- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004919 that the SMTP.starttls() caller no longer needs to call ehlo()
4920 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004921 does not claim to support starttls. Adds the
4922 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5003 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5004 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005021 time so that opening a database previously created with the DB_DUP
5022 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5023 opens. Specifically: dictionary assignment to a DB object will
5024 replace all values for a given key when the database allows
5025 duplicate values. DB users should use DB.put(k, v) when they want
5026 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005027

5033 characters with ASCII value less than 32. Also, it correctly quotes
5034 dots only if they occur on a single line, as opposed to the previous
5035 behavior of quoting dots if they are the second character of any
5036 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005372- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5373 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5374 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005375
5376- Patch #1720595: add T_BOOL to the range of structmember types.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005381- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5382 of w# format code incorrectly truncated the length to an int, even
5383 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5384 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005385
Georg Brandl3ee81df2008-05-17 18:14:43 +00005386- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5387 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005389- PEP 3123: Provide forward compatibility with Python 3.0, while
5390 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5391 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005393- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5394 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005395
5396- Patch #1733960: Allow T_LONGLONG to accept ints.

5403
5404- Fix some leftovers from the conversion from int to Py_ssize_t
5405 (relevant to strings and sequences of more than 2**31 items).
5406
5407- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5408 outside of pystate.c and should not be necessary.
5409
Georg Brandl3ee81df2008-05-17 18:14:43 +00005410- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5411 absolute imports. In earlier versions they might have used relative

Georg Brandl3ee81df2008-05-17 18:14:43 +00005414- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5415 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005416
Georg Brandl3ee81df2008-05-17 18:14:43 +00005417- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005424- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5425 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5426 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5427 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005428
Georg Brandl3ee81df2008-05-17 18:14:43 +00005429- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005442- Removed the macfs module. It had been deprecated since Python 2.5.
5443 This lead to the deprecation of macostools.touched() as it relied
5444 solely on macfs and was a no-op under OS X.
