122 encoded string for them. This ensure that the upload and register commands
123 send the right values to PyPI without any error.
124
R. David Murrayed44dfa2010-01-16 05:15:17 +0000125- Issue #1670765: Prevent email.generator.Generator from re-wrapping

201-----------------
202
Benjamin Petersonecdae192010-01-04 00:43:01 +0000203- The __complex__ method is now looked up on the class of instances to make it

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000206- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
207 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
208
Mark Dickinson1b34d252010-01-01 17:27:30 +0000209- Issue #5080: A number of functions and methods previously produced a
210 DeprecationWarning when passed a float argument where an integer was
211 expected. These functions and methods now raise TypeError instead.
212 The majority of the effects of this change are in the extension
213 modules, but some core functions and methods are affected: notably
214 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
215 methods.
216
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000217- Issue #7604: Deleting an unset slotted attribute did not raise an

225
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000226- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
227 used to drop the time part of the result.
228
Mark Dickinson46572832009-12-27 14:55:57 +0000229- Issue #1811: improve accuracy and cross-platform consistency for
230 true division of integers: the result of a/b is now correctly
231 rounded for ints a and b (at least on IEEE 754 platforms), and in
232 particular does not depend on the internal representation of a long.
233
Ezio Melottif84caf42009-12-24 22:25:17 +0000234- Issue #6108: unicode(exception) and str(exception) should return the same

236
Ronald Oussoren92919a62009-12-24 13:30:58 +0000237- Issue #6834: replace the implementation for the 'python' and 'pythonw'
238 executables on OSX.
239

241 ``arch -ppc python`` will start a universal binary version of python
242 in PPC mode (unlike previous releases).
243

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000301- Issue #7349: Make methods of file objects in the io module accept None as an
302 argument where file-like objects (ie StringIO and BytesIO) accept them to mean

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

380 with invalid values.
381
Eric Smithc4ab8332009-11-29 17:40:57 +0000382- Issue #3382: 'F' formatting for float and complex now convert the
383 result to upper case. This only affects 'inf' and 'nan', since 'f'
384 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000385
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000386- Remove switch from "%f" formatting to "%g" formatting for floats
387 larger than 1e50 in absolute value.
388
Mark Dickinson18cfada2009-11-23 18:46:41 +0000389- Remove restrictions on precision when formatting floats. E.g.,
390 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
391 requested 120 significant digits instead.
392
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000393- Add Py3k warnings for parameter names in parenthesis.

398 on MacOSX 10.6.
399
Mark Dickinsonb678de82009-11-19 18:41:49 +0000400- Issue #7117: repr(x) for a float x returns a result based on the
401 shortest decimal string that's guaranteed to round back to x under
402 correct rounding (with round-half-to-even rounding mode).
403 Previously it gave a string based on rounding x to 17 decimal digits.
404 repr(x) for a complex number behaves similarly. On platforms where
405 the correctly-rounded strtod and dtoa code is not supported (see below),
406 repr is unchanged.
407
408- Issue #7117: On almost all platforms: float-to-string and
409 string-to-float conversions within Python are now correctly rounded.
410 Places these conversions occur include: str for floats and complex
411 numbers; the float and complex constructors; old-style and new-style
412 numeric formatting; serialization and deserialization of floats and
413 complex numbers using marshal, pickle and json; parsing of float and
414 imaginary literals in Python code; Decimal-to-float conversion.
415
416 The conversions use a Python-adapted version of David Gay's
417 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
418 functions. This code is supported on Windows, and on Unix-like
419 platforms using gcc, icc or suncc as the C compiler. There may be a
420 small number of platforms on which correct operation of this code
421 cannot be guaranteed, so the code is not used: notably, this applies
422 to platforms where the C double format is not IEEE 754 binary64, and
423 to platforms on x86 hardware where the x87 FPU is set to 64-bit
424 precision and Python's configure script is unable to determine how
425 to change the FPU precision. On these platforms conversions use the
426 platform strtod and dtoa, as before.
427
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000428- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000429 now uses the correctly-rounded string <-> float conversions
430 described above (when available), and so produces correctly rounded
431 results that will display nicely under the float repr. There are
432 two related small changes: (1) round now accepts any class with an
433 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000434 floats for the second argument), and (2) an excessively large second
435 integer argument (e.g., round(1.234, 10**100)) no longer raises an
436 exception.

Eric Smitha985a3a2009-05-05 18:26:08 +0000584- Issue #5920: For float.__format__, change the behavior with the
585 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
586 to be like 'g' but with at least one decimal point and with a
587 default precision of 12. Previously, the behavior the same but with
588 a default precision of 6. This more closely matches str(), and
589 reduces surprises when adding alignment flags to the empty
590 presentation type. This also affects the new complex.__format__ in
591 the same way.

656 untrackable objects are not tracked by the garbage collector. This can
657 reduce the size of collections and therefore the garbage collection overhead
658 on long-running programs, depending on their particular use of datatypes.

663
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000664- Issue #4258: Make it possible to use base 2**30 instead of base
665 2**15 for the internal representation of integers, for performance
666 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
667 --enable-big-digits option to configure, which overrides the
668 default. Add sys.long_info structseq to provide information about
669 the internal format.

686 float arguments.
687
Raymond Hettinger08259e82009-02-18 23:10:19 +0000688- Running Python with the -3 option now also warns about classic division
689 for ints and longs.
690

692 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
693 on a 64-bit system.
694
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000695- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

702
Georg Brandl29c6a282009-04-05 20:23:13 +0000703- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000704 were suppressing all exceptions. These include list(), filter(), map(),
705 zip(), and bytearray().
706
Benjamin Peterson596d3062009-01-19 15:42:23 +0000707- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000726- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
727 collecting the oldest generation) so that allocating lots of objects without
728 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000729 Martin von Löwis at

733
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000734- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
735 an existing .py counterpart, override the co_filename attributes of all
736 code objects if the original filename is obsolete (which can happen if the
737 file has been renamed, moved, or if it is accessed through different paths).
738 Patch by Ziga Seilnacht and Jean-Paul Calderone.

750
Benjamin Peterson7af65562008-12-29 17:56:58 +0000751- Issue #4764: With io.open, IOError.filename is set when trying to open a

759
Skip Montanarof205c132008-12-23 03:30:15 +0000760- Added test case to ensure attempts to read from a file opened for writing
761 fail.
762
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000763- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

776 exceptions.
777
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000778- Issue #4445: Replace "sizeof(PyStringObject)" with
779 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
780 str instances. On a typical machine this saves 3 bytes of memory
781 (on average) per string allocation.
782
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000783- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
784 interpreter to abort ("Fatal Python error: Could not reset the stack!")
785 instead of throwing a MemoryError.
786
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000787- Issue #3689: The list reversed iterator now supports __length_hint__

789
Benjamin Petersonc078f922008-11-21 22:27:24 +0000790- Issue #4367: Python would segfault during compiling when the unicodedata

792
Vinay Sajip213faca2008-12-03 23:22:58 +0000793- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000794 method on file objects with closefd=False. The file descriptor is still
795 kept open but the file object behaves like a closed file. The ``FileIO``
796 object also got a new readonly attribute ``closefd``.
797
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000798- Issue #4348: Some bytearray methods returned that didn't cause any change to

809
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000810- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
811 method does not return iterators for the 4th and 5th items.
812
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000813- Issue #4209: Enabling unicode_literals and the print_function in the same
814 __future__ import didn't work.
815
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000816- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000817 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000819- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
820 returned a path longer than MAX_PATH. (But It's doubtful this code path is
821 really executed because I cannot move to such directory on win2k)
822
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000823- Issue #4069: When set.remove(element) is used with a set element, the element
824 is temporarily replaced with an equivalent frozenset. But the eventual
825 KeyError would always report the empty frozenset([]) as the missing key. Now
826 it correctly refers to the initial element.

844 returned them on 64bit platforms.
845
Walter Dörwalded960ac2009-05-03 22:36:33 +0000846- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
847 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
848 step. This avoids problems with counting UTF-8 bytes that ignores the effect
849 of using the replace error handler in PyUnicode_DecodeUTF8().
850
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000851- Issue #3739: The unicode-internal encoder now reports the number of characters
852 consumed like any other encoder (instead of the number of bytes).
853
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000854- Issue #2422: When compiled with the ``--with-valgrind`` option, the
855 pymalloc allocator will be automatically disabled when running under
856 Valgrind. This gives improved memory leak detection when running
857 under Valgrind, while taking advantage of pymalloc at other times.

2238
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002239- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2240 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2241 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2242 ``printf`` function, whereas PyString_FromFormat has an independent
2243 implementation and uses "%zd" on all platforms for size_t values.
2244 This makes a difference on win64, where ``printf`` needs "%Id" to display
2245 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002247- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2251 object; previously an int would be returned for small values. the __long__
2252 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002262 was correctly parsed but parsing of subsequent arguments failed.
2263
Vinay Sajip35e3b032008-09-01 14:33:59 +00002264- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002265 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2266 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2267 when given a tuple of classes as second argument, were looking up
2268 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2269 type object.

2340 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2341 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002408What's New in Python 2.6 beta 3?
2409================================
2410
Barry Warsaw07a4a382008-08-21 01:15:08 +00002411*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002412
2413Core and Builtins
2414-----------------
2415
Guido van Rossumf8402962008-08-20 15:01:50 +00002416- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2417 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2418 extensions do not automatically benefit from the class attribute
2419 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2420 to their tp_flags field if they care. This is a backwards
2421 compatibility feature; in 3.0, all types will use the cache by
2422 default.
2423
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002424- Keyword arguments can now follow starred arguments. (``f(a, *args,
2425 keyword=23)`` is now valid syntax.)
2426
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002427- ctypes function pointers that are COM methods have a boolean True
2428 value again.
2429
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002430- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2431 by denying s# to parse objects that have a releasebuffer procedure,
2432 and introducing s*.
2433
Georg Brandl1e13ea92008-08-11 09:07:59 +00002434- Issue #3537: Fix an assertion failure when an empty but presized dict
2435 object was stored in the freelist.
2436
Mark Dickinsonb6467572008-08-04 21:30:09 +00002437- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2438 ValueError consistently across platforms.
2439
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002440- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2441 (64bit Unix, for example), unichr() would truncate its argument and return
2442 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2443
Neal Norwitze7d8be82008-07-31 17:17:14 +00002444- Apply security patches from Apple.
2445
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002446- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2447 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2448
Antoine Pitrou92f82162008-07-25 22:22:08 +00002449- Issue #1819: function calls with several named parameters are now on
2450 average 35% faster (as measured by pybench).
2451
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002452- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2453 the python debugger steps into a class statement: the free variables (local
2454 variables defined in an outer scope) would be deleted from the outer scope.
2455
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002456- Issue #2620: Overflow checking when allocating or reallocating memory
2457 was not always being done properly in some python types and extension
2458 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2459 all been updated to perform better checks and places in the code that
2460 would previously leak memory on the error path when such an allocation
2461 failed have been fixed.

2465
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002466- Issue #3612: Added some missing basic types in ctypes.wintypes.
2467
Benjamin Petersone977ad42008-08-20 01:42:01 +00002468- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2469 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2470
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002471- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2472 version reported by these tools does not necessarily follow the python
2473 version numbering scheme, so the module is less strict when parsing it.
2474
Nick Coghlanf70385a2008-08-18 12:42:46 +00002475- Issue #2235: Added Py3k warnings for types which will become unhashable
2476 under the stricter __hash__ inheritance rules in 3.0. Several types
2477 which did not meet the rules for hash invariants and were already
2478 unhashable in 3.0 have now been explicitly flagged as unhashable in
2479 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2480 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2481
Brett Cannon88f801d2008-08-18 00:46:22 +00002482- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2483 imported into the module but exposed as part of the module's API.
2484
Brett Cannon7b96f072008-08-18 00:41:11 +00002485- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2486
Brett Cannon46225e72008-08-18 00:36:52 +00002487- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2488
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002489- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2490
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002491- Issue #3575: Incremental decoder's decode function now takes bytearray
2492 by using 's*' instead of 't#'.
2493
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002494- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002495 fails unicode conversion on 2nd parameter. (windows only)
2496
Facundo Batista94f243a2008-08-17 03:38:39 +00002497- Issue 2464. urllib2 now supports a malformation in the URL received
2498 in a redirect.
2499
Brett Cannonabe423e2008-08-16 21:47:07 +00002500- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002501 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002502
Facundo Batistaeb90b782008-08-16 14:44:07 +00002503- Issue #2776: fixed small issue when handling an URL with double slash
2504 after a 302 response in the case of not going through a proxy.
2505
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002506- Issue #2676: in the email package, content-type parsing was hanging on
2507 pathological input because of quadratic or exponential behaviour of a
2508 regular expression.
2509
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002510- Issue #3476: binary buffered reading through the new "io" library is now
2511 thread-safe.
2512
Brett Cannonbf3157b2008-08-14 05:00:03 +00002513- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2514 since mimetools itself is deprecated. Because modules are cached, all
2515 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2516
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002517- Issue #3134: shutil referenced undefined WindowsError symbol.
2518
Robert Schuppenies14646332008-08-10 11:01:53 +00002519- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2520 menu entries were not deleted.
2521
Brett Cannon83e81842008-08-09 23:30:55 +00002522- Copied the implementation of reduce() to _functools.reduce() to have a
2523 version that did not raise a DeprecationWarning under -3.
2524
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002525- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2526 a MemoryError rather than silently stop the iteration.
2527
Guido van Rossum59ce9012008-08-09 14:55:34 +00002528- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2529 to _sre.compile() will now be rejected. This should not affect anybody
2530 since the re.compile() function never generates invalid re-bytecode.
2531
Skip Montanaroa032bf42008-08-08 22:52:51 +00002532- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2533 upon first access it can be automatically initialized from the csv file if
2534 it wasn't initialized during instantiation.
2535
Brett Cannon3aa2a492008-08-06 22:28:09 +00002536- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2537 the reload() built-in has been removed.
2538
Brett Cannon7e30b672008-08-04 21:52:25 +00002539- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002540 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002551 asking for a specific length. This problem only affected files opened
2552 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002553

2603================================
2604
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002605*Release date: 17-Jul-2008*

2608-----------------
2609
Georg Brandl3e483f62008-07-16 22:57:41 +00002610- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2611 its methods now allow for items objects that can be converted to
2612 an integer using operator.index().
2613
Mark Dickinson64b7e502008-07-16 09:40:03 +00002614- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2615 produced a ValueError instead of giving the correct float.
2616
Eric Smitha5fa5a22008-07-16 00:11:49 +00002617- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2618 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2619
Mark Dickinson7103aa42008-07-15 19:08:33 +00002620- Issue #3008: the float type has a new instance method 'float.hex'
2621 and a new class method 'float.fromhex' to convert floating-point
2622 numbers to and from hexadecimal strings, respectively.
2623
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002624- Issue #2235: __hash__ is once again inherited by default. To allow
2625 collections.Hashable to remain meaningful in the presence of the
2626 default hash implementation (object.__hash__), it is now possible
2627 to explicit block inheritance of hash by setting __hash__=None at
2628 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2629 level.
2630
Nick Coghlanb028f502008-07-13 14:52:36 +00002631- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2632 the parent module cannot be found while performing an absolute import.
2633 This means that an incorrectly defined __package__ attribute will
2634 now only prevent relative imports in that module rather than causing
2635 all imports from that module to fail.
2636
Nick Coghlan14ff9942008-07-08 14:21:42 +00002637- Issue #2517: Allow unicode messages in Exceptions again by correctly
2638 bypassing the instance dictionary when looking up __unicode__ on

2642 set to a custom object whose write() method happens to install
2643 another file in sys.stdout.
2644
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002645- Issue #3088: Corrected a race condition in classes derived from
2646 threading.local: the first member set by a thread could be saved in
2647 another thread's dictionary.
2648
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002649- Issue #3004: Minor change to slice.indices(): the start and stop
2650 arguments are now treated identically, making the behaviour easier
2651 to describe and understand. For example, slice(None, -10,
2652 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2653 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2654 10, -1).
2655
Georg Brandl278fc502008-07-19 12:46:12 +00002656- Issue #3219: Calling a function with repeated keyword arguments,
2657 f(a=2, a=23), would not cause a syntax error. This was a regression
2658 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002659
Georg Brandl278fc502008-07-19 12:46:12 +00002660- Issue #2862: Make int and float freelist management consistent with
2661 other freelists. Changes their CompactFreeList apis into
2662 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002667- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2668 api functions without holding the GIL, which could lead to a fatal
2669 error when they failed.
2670
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002671- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002696- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2697 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002698 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002699 content-length. The problem had been corrected in the 2.4 branch, but never
2700 merged into trunk.
2701
Georg Brandle78fbcc2008-07-05 10:13:36 +00002702- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002715- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2716 handling is now the same as that of other special attributes like __name__).
2717
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002718- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00003170- Issue #1631171: Re-implement the 'warnings' module in C (the
3171 original Python code has been kept as backup). This will allow for
3172 using the 'warning's machinery in such places as the parser where
3173 use of pure Python code is not possible. Both the ``showarning()``
3174 and ``formatwarning()`` gain an optional 'line' argument which is
3175 not called by default for backwards-compatibility reasons. Setting
3176 ``warnings.showwarning()`` to an implementation that lacks support
3177 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003240- Issue #2550: The approach used by client/server code for obtaining
3241 ports to listen on in network-oriented tests has been refined in an
3242 effort to facilitate running multiple instances of the entire
3243 regression test suite in parallel without issue.
3244 test_support.bind_port() has been fixed such that it will always
3245 return a unique port -- which wasn't always the case with the
3246 previous implementation, especially if socket options had been set
3247 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3248 new implementation of bind_port() will actually raise an exception
3249 if it is passed an AF_INET/SOCK_STREAM socket with either the
3250 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3251 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3252 the socket it's been passed. This currently only applies to
3253 Windows. This option prevents any other sockets from binding to the
3254 host/port we've bound to, thus removing the possibility of the
3255 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3256 when a second SOCK_STREAM socket binds and accepts to a host/port
3257 that's already been bound by another socket. The optional preferred
3258 port parameter to bind_port() has been removed. Under no
3259 circumstances should tests be hard coding ports!
3260
3261 test_support.find_unused_port() has also been introduced, which will
3262 pass a temporary socket object to bind_port() in order to obtain an
3263 unused port. The temporary socket object is then closed and
3264 deleted, and the port is returned. This method should only be used
3265 for obtaining an unused port in order to pass to an external program
3266 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3267 a parameter to a server-oriented class that doesn't give you direct
3268 access to the underlying socket used.
3269
3270 Finally, test_support.HOST has been introduced, which should be used
3271 for the host argument of any relevant socket calls (i.e. bind and
3272 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003273
3274 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003275 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003276 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3277 test_asynchat and test_socket_ssl.
3278
Georg Brandl3ee81df2008-05-17 18:14:43 +00003279 It is now possible for multiple instances of the regression test
3280 suite to run in parallel without issue.

3548
Fred Drakea8ee94b2008-03-01 02:45:07 +00003549- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003550 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003556- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003557 issue 215555 for a discussion.
3558
Eric Smitha73fbe72008-02-23 03:09:44 +00003559- Added the future_builtins module, which contains hex() and oct().
3560 These are the PEP 3127 version of these functions, designed to be
3561 compatible with the hex() and oct() builtins from Python 3.0. They
3562 differ slightly in their output formats from the existing, unchanged
3563 Python 2.6 builtins. The expected usage of the future_builtins
3564 module is:
3565 from future_builtins import hex, oct
3566
Eric Smith7ef40bf2008-02-20 23:34:22 +00003567- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3568 exponents for exponents with absolute value < 100. Follows C99
3569 standard. This is a change on Windows, which would use 3 digits.
3570 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3571 so that any alterations it does to the resulting string will be
3572 available in stringlib/formatter.h (for float.__format__).
3573
Eric Smith5a3c1352008-02-19 13:21:56 +00003574- Implemented PEP 3101, Advanced String Formatting. This adds a new
3575 builtin format(); a format() method for str and unicode; a
3576 __format__() method to object, str, unicode, int, long, float, and
3577 datetime; the class string.Formatter; and the C API
3578 PyObject_Format().
3579
Georg Brandl3ee81df2008-05-17 18:14:43 +00003580- Fixed several potential crashes, all caused by specially crafted
3581 __del__ methods exploiting objects in temporarily inconsistent
3582 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003583
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003584- Issue #2115: Important speedup in setting __slot__ attributes. Also

3606 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003607 to compact the internal free lists of pre-allocted ints and floats.
3608
Georg Brandl3ee81df2008-05-17 18:14:43 +00003609- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3610 calls. Python expected the return type int but the fork familie
3611 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003625- Patch #1473257: generator objects gain a gi_code attribute. This is
3626 the same object as the func_code attribute of the function that
3627 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003628
Georg Brandl3ee81df2008-05-17 18:14:43 +00003629- Issue #1920: "while 0" statements were completely removed by the
3630 compiler, even in the presence of an "else" clause, which is
3631 supposed to be run when the condition is false. Now the compiler
3632 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003633

Georg Brandl6caad7d2008-01-26 14:19:22 +00003651- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003652 added.
3653
Christian Heimesc94e2b52008-01-14 04:13:37 +00003654- sys.float_info / PyFloat_GetInfo: The floating point information
3655 object was converted from a dict to a specialized structseq object.
3656
Georg Brandl3ee81df2008-05-17 18:14:43 +00003657- Patch #1816: Added sys.flags structseq. It exposes the status of
3658 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003659
Georg Brandl3ee81df2008-05-17 18:14:43 +00003660- Objects/structseq.c: Implemented new structseq representation. The
3661 patch makes structseqs (e.g. the return value of os.stat) more
3662 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003663
Georg Brandl3ee81df2008-05-17 18:14:43 +00003664- Patch #1700288: added a type attribute cache that caches method
3665 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003666
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003667- Bug #1776: __import__() no longer accepts filenames on any platform.
3668 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003669
Georg Brandlaed6c662008-01-07 17:25:53 +00003670- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3671
Georg Brandl3ee81df2008-05-17 18:14:43 +00003672- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3673 envvar and sys.dont_write_bytecode attribute. All these can be set
3674 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003675
Georg Brandl3ee81df2008-05-17 18:14:43 +00003676- Improve some exception messages when Windows fails to load an
3677 extension module. Now we get for example '%1 is not a valid Win32
3678 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003679

Christian Heimes0a8143f2007-12-18 23:22:54 +00003685- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003686 and INF. float("nan"), float("inf") and float("-inf") now work on
3687 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003688
Georg Brandl3ee81df2008-05-17 18:14:43 +00003689- Compiler now generates simpler and faster code for dictionary
3690 literals. The oparg for BUILD_MAP now indicates an estimated
3691 dictionary size. There is a new opcode, STORE_MAP, for adding
3692 entries to the dictionary.

3710 running, and if the deallocation of its frames somehow calls the
3711 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003712

Georg Brandl3ee81df2008-05-17 18:14:43 +00003721- Patch #1739468: Directories and zipfiles containing a __main__.py
3722 file can now be directly executed by passing their name to the
3723 interpreter. The directory/zipfile is automatically inserted as the
3724 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003725
Georg Brandl3ee81df2008-05-17 18:14:43 +00003726- Issue #1265: Fix a problem with sys.settrace, if the tracing
3727 function uses a generator expression when at the same time the
3728 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003729
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003730- sets and frozensets now have an isdisjoint() method.
3731

3733
Neal Norwitz44f326e2007-10-05 05:29:17 +00003734- Fix warnings found by the new version of the Coverity checker.
3735
Georg Brandl3ee81df2008-05-17 18:14:43 +00003736- The enumerate() builtin function is no longer bounded to sequences
3737 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3738 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003739
Georg Brandl3ee81df2008-05-17 18:14:43 +00003740- Issue #1686386: Tuple's tp_repr did not take into account the
3741 possibility of having a self-referential tuple, which is possible
3742 from C code. Nor did object's tp_str consider that a type's tp_str
3743 could do something that could lead to an inifinite recursion.
3744 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3745 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003746
Georg Brandl3ee81df2008-05-17 18:14:43 +00003747- Issue #1164: It was possible to trigger deadlock when using the
3748 'print' statement to write to a file since the GIL was not released
3749 as needed. Now PyObject_Print() does the right thing along with
3750 various tp_print implementations of the built-in types and those in
3751 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003752
Georg Brandl3ee81df2008-05-17 18:14:43 +00003753- Issue #1147: Exceptions were directly allowing string exceptions in
3754 their throw() method even though string exceptions no longer
3755 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003756
Georg Brandl3ee81df2008-05-17 18:14:43 +00003757- Issue #1096: Prevent a segfault from getting the repr of a very
3758 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003759
Brett Cannon1e534b52007-09-07 04:18:30 +00003760- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003761 PyObject_Call() never calling back out to Python code to trigger
3762 recursion depth updates/checks. Required the creation of a static
3763 RuntimeError instance in case normalizing an exception put the
3764 recursion check value past its limit. Fixes crashers
3765 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003766
Georg Brandl3ee81df2008-05-17 18:14:43 +00003767- Patch #1031213: Decode source line in SyntaxErrors back to its

3771 with %G.
3772
Georg Brandl3ee81df2008-05-17 18:14:43 +00003773- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00003780- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003781 __*__ attributes. (Some already existed, e.g., __doc__ and
3782 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003783
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003784- Add -3 option to the interpreter to warn about features that are
3785 deprecated and will be changed/removed in Python 3.0.
3786
Georg Brandl2134e752007-05-21 20:34:16 +00003787- Patch #1686487: you can now pass any mapping after '**' in function
3788 calls.
3789
Collin Winter62903052007-05-18 23:11:24 +00003790- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003791 "except E as target:". This is to provide forwards compatibility
3792 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003793
Brett Cannon229cee22007-05-05 01:34:02 +00003794- Deprecate BaseException.message as per PEP 352.
3795
Georg Brandl3ee81df2008-05-17 18:14:43 +00003796- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003797 inherited from a builtin base.
3798
Vinay Sajip8549ce32007-05-06 17:53:37 +00003799- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003800 setting a plain string, ie don't expand to single letter identifiers.
3801
Raymond Hettinger13936692007-04-11 18:40:58 +00003802- Request #1191699: Slices can now be pickled.
3803
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003804- Request #1193128: str.translate() now allows a None argument for
3805 translations that only remove characters without re-mapping the
3806 remaining characters.
3807
Georg Brandl5cb76c12007-03-21 09:00:39 +00003808- Patch #1682205: a TypeError while unpacking an iterable is no longer
3809 masked by a generic one with the message "unpack non-sequence".
3810
Neal Norwitzaa754b72007-03-21 06:39:48 +00003811- Remove unused file Python/fmod.c.
3812
Guido van Rossum143b5642007-03-23 04:58:42 +00003813- Bug #1683368: The object.__init__() and object.__new__() methods are
3814 now stricter in rejecting excess arguments. The only time when
3815 either allows excess arguments is when it is not overridden and the
3816 other one is. For backwards compatibility, when both are
3817 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003818 warning later). Also, type.__init__() insists on the same signature
3819 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003820
Georg Brandl3ee81df2008-05-17 18:14:43 +00003821- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3822 object to complex using its __complex__() method before falling back
3823 to the __float__() method. Therefore, the functions in the cmath
3824 module now can operate on objects that define a __complex__()
3825 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003826
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827- Patch #1623563: allow __class__ assignment for classes with
3828 __slots__. The old and the new class are still required to have the
3829 same slot names.

3835 ``object.__reduce_ex__()`` is called with an object that is faking
3836 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003837
Georg Brandl3ee81df2008-05-17 18:14:43 +00003838- Patch #1680015: Don't modify __slots__ tuple if it contains an

3842
Georg Brandl7b9c5552007-03-12 14:30:05 +00003843- Bug #1678647: write a newline after printing an exception in any
3844 case, even when converting the value to a string failed.
3845
Georg Brandl871f1bc2007-03-12 13:17:36 +00003846- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003847 its argument, if it exists. If not, it will work like before. This
3848 allows customizing the output of dir() in the presence of a
3849 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003850
Collin Winter276887b2007-03-12 16:11:39 +00003851- Patch #922167: Python no longer segfaults when faced with infinitely
3852 self-recursive reload() calls (as reported by bug #742342).
3853
Georg Brandl3ee81df2008-05-17 18:14:43 +00003854- Patch #1675981: remove unreachable code from ``type.__new__()``

3858 parthensized forms. This means complex(repr(x)) now works instead of
3859 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003860
Georg Brandlaa2321b2007-03-07 00:40:28 +00003861- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862 makes the filenames the warning module prints much more sensible
3863 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003864
Georg Brandl49aafc92007-03-07 00:34:46 +00003865- Variant of patch #697613: don't exit the interpreter on a SystemExit
3866 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867 variable is given, but break into the interactive interpreter just
3868 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003876- Patch #1674228: when assigning a slice (old-style), check for the
3877 sq_ass_slice instead of the sq_slice slot.
3878
Georg Brandl3ee81df2008-05-17 18:14:43 +00003879- When printing an unraisable error, don't print exceptions. before
3880 the name. This duplicates the behavior whening normally printing
3881 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004383- Added a timeout parameter to the constructor of other protocols
4384 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4385 work started with create_connection() and timeout in httplib, and
4386 closes patch #723312.
4387
Vinay Sajip8549ce32007-05-06 17:53:37 +00004388- Patch #1676823: Added create_connection() to socket.py, which may be
4389 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004390 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004391
Martin v. Löwis0af33882007-03-23 13:27:15 +00004392- Bug #978833: Revert r50844, as it broke _socketobject.dup.

4412
Georg Brandlf66b6032007-03-14 08:27:52 +00004413- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004414 AttributeError instead of an IOError when the server's response
4415 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004416
Georg Brandl3ee81df2008-05-17 18:14:43 +00004417- Patch #957650: "%var%" environment variable references are now
4418 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00004421- Patch #1429539: pdb now correctly initializes the __main__ module
4422 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004423 correctly now.
4424
Georg Brandlbad6f192007-03-13 21:32:56 +00004425- The nonobvious commands.getstatus() function is now deprecated.

4431
Georg Brandl3ee81df2008-05-17 18:14:43 +00004432- Patch #1530482: add pydoc.render_doc() which returns the
4433 documentation for a thing instead of paging it to stdout, which

4442 parameter which can be set to False to prevent the default
4443 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00004444
Georg Brandl9e6b4702007-03-13 18:15:41 +00004445- Patch #1581073: add a flag to textwrap that prevents the dropping of
4446 whitespace while wrapping.
4447
Georg Brandl92a6bae2007-03-13 17:43:32 +00004448- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004449 are set for invalid interpolation sequences that would lead to
4450 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004451

Georg Brandl3ee81df2008-05-17 18:14:43 +00004466 field names in its exception message if you try to write a record
4467 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004485

4493 returned string up to the first NUL character.
4494

4504
Georg Brandl3ee81df2008-05-17 18:14:43 +00004505- unittest now verifies more of its assumptions. In particular,
4506 TestCase and TestSuite subclasses (not instances) are no longer
4507 accepted in TestSuite.addTest(). This should cause no
4508 incompatibility since it never made sense with ordinary subclasses
4509 -- the failure just occurred later, with a more cumbersome
4510 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00004511

4519 given a unicode argument and os.listdir() returns unicode filenames.
4520
Georg Brandl3ee81df2008-05-17 18:14:43 +00004521- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00004899 time so that opening a database previously created with the DB_DUP
4900 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4901 opens. Specifically: dictionary assignment to a DB object will
4902 replace all values for a given key when the database allows
4903 duplicate values. DB users should use DB.put(k, v) when they want
4904 to store duplicates; not DB[k] = v.

4911 characters with ASCII value less than 32. Also, it correctly quotes
4912 dots only if they occur on a single line, as opposed to the previous
4913 behavior of quoting dots if they are the second character of any
4914 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004915

Georg Brandl3ee81df2008-05-17 18:14:43 +00005292- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5293 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
