47 and read operations on write-only file objects. On Windows, the system C
48 library would return a bogus result; on Solaris, it was possible to crash
49 the interpreter. Patch by Stefan Krah.
50
Barry Warsawb1e66ee2010-02-05 18:45:25 +000051- Issue #7853: Normalize exceptions before they are passed to a context

65 suite_mask, and product_type.
66
Antoine Pitroue80a6a42010-01-17 12:26:20 +000067- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
68 could crash in many places because of the PyByteArray_AS_STRING() macro
69 returning NULL. The macro now returns a statically allocated empty
70 string instead.
71

81 some values large enough to cause overflow, and (4) a number of
82 flaws that could lead to incorrectly rounded results.

102 allowed by the XML specification, and are necessary when outputting e.g.
103 PHP code in a processing instruction. Patch by Neil Muller.

119 file position when calling `truncate()`. It would previously change the
120 file position to the given argument, which goes against the tradition of
121 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000139- Issue #7748: Since unicode values are supported for some metadata options
140 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
141 encoded string for them. This ensure that the upload and register commands
142 send the right values to PyPI without any error.
143
R. David Murrayed44dfa2010-01-16 05:15:17 +0000144- Issue #1670765: Prevent email.generator.Generator from re-wrapping

220-----------------
221
Benjamin Petersonecdae192010-01-04 00:43:01 +0000222- The __complex__ method is now looked up on the class of instances to make it

227
Mark Dickinson1b34d252010-01-01 17:27:30 +0000228- Issue #5080: A number of functions and methods previously produced a
229 DeprecationWarning when passed a float argument where an integer was
230 expected. These functions and methods now raise TypeError instead.
231 The majority of the effects of this change are in the extension
232 modules, but some core functions and methods are affected: notably
233 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
234 methods.
235
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000236- Issue #7604: Deleting an unset slotted attribute did not raise an

244
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000245- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
246 used to drop the time part of the result.
247
Mark Dickinson46572832009-12-27 14:55:57 +0000248- Issue #1811: improve accuracy and cross-platform consistency for
249 true division of integers: the result of a/b is now correctly
250 rounded for ints a and b (at least on IEEE 754 platforms), and in
251 particular does not depend on the internal representation of a long.
252
Ezio Melottif84caf42009-12-24 22:25:17 +0000253- Issue #6108: unicode(exception) and str(exception) should return the same

264 the underlying error when the coercion fails for the left hand operand.
265
Benjamin Peterson4895af42009-12-13 16:36:53 +0000266- Issue #7491: Metaclass's __cmp__ method was ignored.
267
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000268- Issue #7466: segmentation fault when the garbage collector is called

399 with invalid values.

Eric Smithc4ab8332009-11-29 17:40:57 +0000401- Issue #3382: 'F' formatting for float and complex now convert the
402 result to upper case. This only affects 'inf' and 'nan', since 'f'
403 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000404
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000405- Remove switch from "%f" formatting to "%g" formatting for floats
406 larger than 1e50 in absolute value.
407
Mark Dickinson18cfada2009-11-23 18:46:41 +0000408- Remove restrictions on precision when formatting floats. E.g.,
409 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
410 requested 120 significant digits instead.
411

417 on MacOSX 10.6.
418
Mark Dickinsonb678de82009-11-19 18:41:49 +0000419- Issue #7117: repr(x) for a float x returns a result based on the
420 shortest decimal string that's guaranteed to round back to x under
421 correct rounding (with round-half-to-even rounding mode).
422 Previously it gave a string based on rounding x to 17 decimal digits.
423 repr(x) for a complex number behaves similarly. On platforms where
424 the correctly-rounded strtod and dtoa code is not supported (see below),
425 repr is unchanged.
426
427- Issue #7117: On almost all platforms: float-to-string and
428 string-to-float conversions within Python are now correctly rounded.
429 Places these conversions occur include: str for floats and complex
430 numbers; the float and complex constructors; old-style and new-style
431 numeric formatting; serialization and deserialization of floats and
432 complex numbers using marshal, pickle and json; parsing of float and
433 imaginary literals in Python code; Decimal-to-float conversion.
434
435 The conversions use a Python-adapted version of David Gay's
436 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
437 functions. This code is supported on Windows, and on Unix-like
438 platforms using gcc, icc or suncc as the C compiler. There may be a
439 small number of platforms on which correct operation of this code
440 cannot be guaranteed, so the code is not used: notably, this applies
441 to platforms where the C double format is not IEEE 754 binary64, and
442 to platforms on x86 hardware where the x87 FPU is set to 64-bit
443 precision and Python's configure script is unable to determine how
444 to change the FPU precision. On these platforms conversions use the
445 platform strtod and dtoa, as before.
446
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000447- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000448 now uses the correctly-rounded string <-> float conversions
449 described above (when available), and so produces correctly rounded
450 results that will display nicely under the float repr. There are
451 two related small changes: (1) round now accepts any class with an
452 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000453 floats for the second argument), and (2) an excessively large second
454 integer argument (e.g., round(1.234, 10**100)) no longer raises an
455 exception.

Eric Smitha985a3a2009-05-05 18:26:08 +0000603- Issue #5920: For float.__format__, change the behavior with the
604 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
605 to be like 'g' but with at least one decimal point and with a
606 default precision of 12. Previously, the behavior the same but with
607 a default precision of 6. This more closely matches str(), and
608 reduces surprises when adding alignment flags to the empty

Antoine Pitrouf8387af2009-03-23 18:41:45 +0000674- Issue #4688: Add a heuristic so that tuples and dicts containing only
675 untrackable objects are not tracked by the garbage collector. This can
676 reduce the size of collections and therefore the garbage collection overhead
677 on long-running programs, depending on their particular use of datatypes.

682
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000683- Issue #4258: Make it possible to use base 2**30 instead of base
684 2**15 for the internal representation of integers, for performance
685 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
686 --enable-big-digits option to configure, which overrides the
687 default. Add sys.long_info structseq to provide information about
688 the internal format.
689
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000690- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

705 float arguments.
706
Raymond Hettinger08259e82009-02-18 23:10:19 +0000707- Running Python with the -3 option now also warns about classic division
708 for ints and longs.
709
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000710- Issue #5260: Long integers now consume less memory: average

712 on a 64-bit system.
713
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000714- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

721
Georg Brandl29c6a282009-04-05 20:23:13 +0000722- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000723 were suppressing all exceptions. These include list(), filter(), map(),
724 zip(), and bytearray().
725
Benjamin Peterson596d3062009-01-19 15:42:23 +0000726- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Antoine Pitrouc2f02212009-01-13 23:13:52 +0000734- Issue #4935: The overflow checking code in the expandtabs() method common
735 to str, bytes and bytearray could be optimized away by the compiler, letting
736 the interpreter segfault instead of raising an error.
737
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000738- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000745- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
746 collecting the oldest generation) so that allocating lots of objects without
747 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000748 Martin von Löwis at

752
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000753- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
754 an existing .py counterpart, override the co_filename attributes of all
755 code objects if the original filename is obsolete (which can happen if the
756 file has been renamed, moved, or if it is accessed through different paths).
757 Patch by Ziga Seilnacht and Jean-Paul Calderone.

766
Nick Coghlan180e4002008-12-30 01:18:48 +0000767- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
768 where the tp_hash and tp_dict slots are both NULL.
769
Benjamin Peterson7af65562008-12-29 17:56:58 +0000770- Issue #4764: With io.open, IOError.filename is set when trying to open a

778
Skip Montanarof205c132008-12-23 03:30:15 +0000779- Added test case to ensure attempts to read from a file opened for writing
780 fail.
781
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000782- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

795 exceptions.
796
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000797- Issue #4445: Replace "sizeof(PyStringObject)" with
798 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
799 str instances. On a typical machine this saves 3 bytes of memory
800 (on average) per string allocation.
801
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000802- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
803 interpreter to abort ("Fatal Python error: Could not reset the stack!")
804 instead of throwing a MemoryError.
805
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000806- Issue #3689: The list reversed iterator now supports __length_hint__

808
Benjamin Petersonc078f922008-11-21 22:27:24 +0000809- Issue #4367: Python would segfault during compiling when the unicodedata

811
Vinay Sajip213faca2008-12-03 23:22:58 +0000812- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000813 method on file objects with closefd=False. The file descriptor is still
814 kept open but the file object behaves like a closed file. The ``FileIO``
815 object also got a new readonly attribute ``closefd``.
816
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000817- Issue #4348: Some bytearray methods returned that didn't cause any change to

831
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000832- Issue #4209: Enabling unicode_literals and the print_function in the same
833 __future__ import didn't work.
834
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000835- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000836 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000838- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
839 returned a path longer than MAX_PATH. (But It's doubtful this code path is
840 really executed because I cannot move to such directory on win2k)
841
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000842- Issue #4069: When set.remove(element) is used with a set element, the element
843 is temporarily replaced with an equivalent frozenset. But the eventual
844 KeyError would always report the empty frozenset([]) as the missing key. Now
845 it correctly refers to the initial element.

864
Walter Dörwalded960ac2009-05-03 22:36:33 +0000865- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
866 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
867 step. This avoids problems with counting UTF-8 bytes that ignores the effect
868 of using the replace error handler in PyUnicode_DecodeUTF8().
869
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000870- Issue #3739: The unicode-internal encoder now reports the number of characters
871 consumed like any other encoder (instead of the number of bytes).
872
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000873- Issue #2422: When compiled with the ``--with-valgrind`` option, the
874 pymalloc allocator will be automatically disabled when running under
875 Valgrind. This gives improved memory leak detection when running
876 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitrou59c44f32009-10-30 17:07:08 +00002112- Issue #7222: Make thread "reaping" more reliable so that reference
2113 leak-chasing test runs give sensible results. The previous method of
2114 reaping threads could return successfully while some Thread objects were

2134 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

2143 test_heapq and test_warnings have been adjusted to use it, tests for
2144 other modules with both C and Python implementations in the stdlib
2145 can be adjusted to use it over time.

Vinay Sajip22aa4bb2009-04-16 19:15:49 +00002154 that should cause a test to be skipped are now done using import_module

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002258- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2259 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2260 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2261 ``printf`` function, whereas PyString_FromFormat has an independent
2262 implementation and uses "%zd" on all platforms for size_t values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002279- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002280 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002281 was correctly parsed but parsing of subsequent arguments failed.
2282
Vinay Sajip35e3b032008-09-01 14:33:59 +00002283- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002284 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2285 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2286 when given a tuple of classes as second argument, were looking up
2287 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2288 type object.
2289
Neal Norwitz18aa3882008-08-24 05:04:52 +00002290- Fix crashes on memory allocation failure found with failmalloc.

2359 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2360 for catch_warnings() also led to an improvement in the raising of a
2361 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002427What's New in Python 2.6 beta 3?
2428================================
2429
Barry Warsaw07a4a382008-08-21 01:15:08 +00002430*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002431
2432Core and Builtins
2433-----------------
2434
Guido van Rossumf8402962008-08-20 15:01:50 +00002435- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2436 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2437 extensions do not automatically benefit from the class attribute
2438 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2439 to their tp_flags field if they care. This is a backwards
2440 compatibility feature; in 3.0, all types will use the cache by
2441 default.
2442
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002443- Keyword arguments can now follow starred arguments. (``f(a, *args,
2444 keyword=23)`` is now valid syntax.)
2445
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002446- ctypes function pointers that are COM methods have a boolean True
2447 value again.
2448
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002449- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2450 by denying s# to parse objects that have a releasebuffer procedure,
2451 and introducing s*.
2452
Georg Brandl1e13ea92008-08-11 09:07:59 +00002453- Issue #3537: Fix an assertion failure when an empty but presized dict
2454 object was stored in the freelist.
2455
Mark Dickinsonb6467572008-08-04 21:30:09 +00002456- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2457 ValueError consistently across platforms.
2458
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002459- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2460 (64bit Unix, for example), unichr() would truncate its argument and return
2461 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2462
Neal Norwitze7d8be82008-07-31 17:17:14 +00002463- Apply security patches from Apple.
2464
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002465- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2466 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2467
Antoine Pitrou92f82162008-07-25 22:22:08 +00002468- Issue #1819: function calls with several named parameters are now on
2469 average 35% faster (as measured by pybench).
2470
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002471- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2472 the python debugger steps into a class statement: the free variables (local
2473 variables defined in an outer scope) would be deleted from the outer scope.
2474
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002475- Issue #2620: Overflow checking when allocating or reallocating memory
2476 was not always being done properly in some python types and extension
2477 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2478 all been updated to perform better checks and places in the code that
2479 would previously leak memory on the error path when such an allocation
2480 failed have been fixed.

2484
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002485- Issue #3612: Added some missing basic types in ctypes.wintypes.
2486
Benjamin Petersone977ad42008-08-20 01:42:01 +00002487- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2488 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2489
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002490- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2491 version reported by these tools does not necessarily follow the python
2492 version numbering scheme, so the module is less strict when parsing it.
2493
Nick Coghlanf70385a2008-08-18 12:42:46 +00002494- Issue #2235: Added Py3k warnings for types which will become unhashable
2495 under the stricter __hash__ inheritance rules in 3.0. Several types
2496 which did not meet the rules for hash invariants and were already
2497 unhashable in 3.0 have now been explicitly flagged as unhashable in
2498 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2499 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2500
Brett Cannon88f801d2008-08-18 00:46:22 +00002501- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2502 imported into the module but exposed as part of the module's API.
2503
Brett Cannon7b96f072008-08-18 00:41:11 +00002504- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2505
Brett Cannon46225e72008-08-18 00:36:52 +00002506- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002508- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2509
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002510- Issue #3575: Incremental decoder's decode function now takes bytearray
2511 by using 's*' instead of 't#'.
2512
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002513- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002514 fails unicode conversion on 2nd parameter. (windows only)
2515
Facundo Batista94f243a2008-08-17 03:38:39 +00002516- Issue 2464. urllib2 now supports a malformation in the URL received
2517 in a redirect.
2518
Brett Cannonabe423e2008-08-16 21:47:07 +00002519- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002520 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002521
Facundo Batistaeb90b782008-08-16 14:44:07 +00002522- Issue #2776: fixed small issue when handling an URL with double slash
2523 after a 302 response in the case of not going through a proxy.
2524
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002525- Issue #2676: in the email package, content-type parsing was hanging on
2526 pathological input because of quadratic or exponential behaviour of a
2527 regular expression.
2528
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002529- Issue #3476: binary buffered reading through the new "io" library is now
2530 thread-safe.
2531
Brett Cannonbf3157b2008-08-14 05:00:03 +00002532- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2533 since mimetools itself is deprecated. Because modules are cached, all
2534 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2535
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002536- Issue #3134: shutil referenced undefined WindowsError symbol.
2537
Robert Schuppenies14646332008-08-10 11:01:53 +00002538- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2539 menu entries were not deleted.
2540
Brett Cannon83e81842008-08-09 23:30:55 +00002541- Copied the implementation of reduce() to _functools.reduce() to have a
2542 version that did not raise a DeprecationWarning under -3.
2543
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002544- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2545 a MemoryError rather than silently stop the iteration.
2546
Guido van Rossum59ce9012008-08-09 14:55:34 +00002547- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2548 to _sre.compile() will now be rejected. This should not affect anybody
2549 since the re.compile() function never generates invalid re-bytecode.
2550
Skip Montanaroa032bf42008-08-08 22:52:51 +00002551- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2552 upon first access it can be automatically initialized from the csv file if
2553 it wasn't initialized during instantiation.
2554
Brett Cannon3aa2a492008-08-06 22:28:09 +00002555- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2556 the reload() built-in has been removed.
2557
Brett Cannon7e30b672008-08-04 21:52:25 +00002558- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002559 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002570 asking for a specific length. This problem only affected files opened

2627-----------------
2628
Georg Brandl3e483f62008-07-16 22:57:41 +00002629- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2630 its methods now allow for items objects that can be converted to
2631 an integer using operator.index().
2632
Mark Dickinson64b7e502008-07-16 09:40:03 +00002633- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2634 produced a ValueError instead of giving the correct float.
2635
Eric Smitha5fa5a22008-07-16 00:11:49 +00002636- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2637 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2638
Mark Dickinson7103aa42008-07-15 19:08:33 +00002639- Issue #3008: the float type has a new instance method 'float.hex'
2640 and a new class method 'float.fromhex' to convert floating-point
2641 numbers to and from hexadecimal strings, respectively.
2642
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002643- Issue #2235: __hash__ is once again inherited by default. To allow
2644 collections.Hashable to remain meaningful in the presence of the
2645 default hash implementation (object.__hash__), it is now possible
2646 to explicit block inheritance of hash by setting __hash__=None at
2647 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2648 level.
2649
Nick Coghlanb028f502008-07-13 14:52:36 +00002650- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2651 the parent module cannot be found while performing an absolute import.
2652 This means that an incorrectly defined __package__ attribute will
2653 now only prevent relative imports in that module rather than causing
2654 all imports from that module to fail.
2655
Nick Coghlan14ff9942008-07-08 14:21:42 +00002656- Issue #2517: Allow unicode messages in Exceptions again by correctly

2666 another thread's dictionary.
2667
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002668- Issue #3004: Minor change to slice.indices(): the start and stop
2669 arguments are now treated identically, making the behaviour easier
2670 to describe and understand. For example, slice(None, -10,
2671 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2672 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2673 10, -1).
2674
Georg Brandl278fc502008-07-19 12:46:12 +00002675- Issue #3219: Calling a function with repeated keyword arguments,
2676 f(a=2, a=23), would not cause a syntax error. This was a regression
2677 from 2.4 caused by the switch to the new compiler.

2680 other freelists. Changes their CompactFreeList apis into

2688 error when they failed.
2689
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002690- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002715- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2716 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002717 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002718 content-length. The problem had been corrected in the 2.4 branch, but never
2719 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002734- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2735 handling is now the same as that of other special attributes like __name__).
2736

Georg Brandl74a1dea2008-05-28 11:21:39 +00003145- Add ``PyType_Modified()`` as a public API to clear the type cache.
3146
3147- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003148
3149- The PyString functions have been renamed to PyBytes. A batch of
3150 defines were added so that the linker still sees the original
3151 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003189- Issue #1631171: Re-implement the 'warnings' module in C (the
3190 original Python code has been kept as backup). This will allow for
3191 using the 'warning's machinery in such places as the parser where
3192 use of pure Python code is not possible. Both the ``showarning()``
3193 and ``formatwarning()`` gain an optional 'line' argument which is
3194 not called by default for backwards-compatibility reasons. Setting
3195 ``warnings.showwarning()`` to an implementation that lacks support
3196 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003238- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003239 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003259- Issue #2550: The approach used by client/server code for obtaining
3260 ports to listen on in network-oriented tests has been refined in an
3261 effort to facilitate running multiple instances of the entire
3262 regression test suite in parallel without issue.
3263 test_support.bind_port() has been fixed such that it will always
3264 return a unique port -- which wasn't always the case with the
3265 previous implementation, especially if socket options had been set
3266 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3267 new implementation of bind_port() will actually raise an exception
3268 if it is passed an AF_INET/SOCK_STREAM socket with either the
3269 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3270 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3271 the socket it's been passed. This currently only applies to
3272 Windows. This option prevents any other sockets from binding to the
3273 host/port we've bound to, thus removing the possibility of the
3274 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3275 when a second SOCK_STREAM socket binds and accepts to a host/port
3276 that's already been bound by another socket. The optional preferred
3277 port parameter to bind_port() has been removed. Under no
3278 circumstances should tests be hard coding ports!
3279
3280 test_support.find_unused_port() has also been introduced, which will
3281 pass a temporary socket object to bind_port() in order to obtain an
3282 unused port. The temporary socket object is then closed and
3283 deleted, and the port is returned. This method should only be used
3284 for obtaining an unused port in order to pass to an external program
3285 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3286 a parameter to a server-oriented class that doesn't give you direct
3287 access to the underlying socket used.
3288
3289 Finally, test_support.HOST has been introduced, which should be used
3290 for the host argument of any relevant socket calls (i.e. bind and
3291 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003292
3293 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003294 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003295 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3296 test_asynchat and test_socket_ssl.
3297
Georg Brandl3ee81df2008-05-17 18:14:43 +00003298 It is now possible for multiple instances of the regression test
3299 suite to run in parallel without issue.

3566-----------------
3567
Fred Drakea8ee94b2008-03-01 02:45:07 +00003568- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003569 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003574
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003575- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003576 issue 215555 for a discussion.
3577
Eric Smitha73fbe72008-02-23 03:09:44 +00003578- Added the future_builtins module, which contains hex() and oct().
3579 These are the PEP 3127 version of these functions, designed to be
3580 compatible with the hex() and oct() builtins from Python 3.0. They
3581 differ slightly in their output formats from the existing, unchanged
3582 Python 2.6 builtins. The expected usage of the future_builtins
3583 module is:
3584 from future_builtins import hex, oct
3585
Eric Smith7ef40bf2008-02-20 23:34:22 +00003586- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3587 exponents for exponents with absolute value < 100. Follows C99
3588 standard. This is a change on Windows, which would use 3 digits.
3589 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3590 so that any alterations it does to the resulting string will be
3591 available in stringlib/formatter.h (for float.__format__).
3592
Eric Smith5a3c1352008-02-19 13:21:56 +00003593- Implemented PEP 3101, Advanced String Formatting. This adds a new
3594 builtin format(); a format() method for str and unicode; a
3595 __format__() method to object, str, unicode, int, long, float, and
3596 datetime; the class string.Formatter; and the C API
3597 PyObject_Format().
3598
Georg Brandl3ee81df2008-05-17 18:14:43 +00003599- Fixed several potential crashes, all caused by specially crafted
3600 __del__ methods exploiting objects in temporarily inconsistent
3601 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003602
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003603- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003604 prevent a possible crash: an Abstract Base Class would try to access
3605 a slot on a registered virtual subclass.

3611 in order to allow pymalloc to free more arenas. Python may give back
3612 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003613
Georg Brandl3ee81df2008-05-17 18:14:43 +00003614- Issue #2045: Fix an infinite recursion triggered when printing a
3615 subclass of collections.defaultdict, if its default_factory is set
3616 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003617
Christian Heimesf75dbef2008-02-08 00:11:31 +00003618- Fixed a minor memory leak in dictobject.c. The content of the free
3619 list was not freed on interpreter shutdown.
3620
Georg Brandl3ee81df2008-05-17 18:14:43 +00003621- Limit free list of method and builtin function objects to 256
3622 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003624- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3625 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003626 to compact the internal free lists of pre-allocted ints and floats.
3627
Georg Brandl3ee81df2008-05-17 18:14:43 +00003628- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3629 calls. Python expected the return type int but the fork familie
3630 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003631
Georg Brandl3ee81df2008-05-17 18:14:43 +00003632- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003644- Patch #1473257: generator objects gain a gi_code attribute. This is
3645 the same object as the func_code attribute of the function that
3646 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003647
Georg Brandl3ee81df2008-05-17 18:14:43 +00003648- Issue #1920: "while 0" statements were completely removed by the
3649 compiler, even in the presence of an "else" clause, which is
3650 supposed to be run when the condition is false. Now the compiler

Guido van Rossumeead05f2008-01-24 18:21:02 +00003653- A few crashers fixed: weakref_in_del.py (issue #1377858);
3654 loosing_dict_ref.py (issue #1303614, test67.py);
3655 borrowed_ref_[34].py (not in tracker).
3656
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003657- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003658 suppressed while an extension is loaded by calling SetErrorMode in
3659 dynload_win.c. The error is still reported properly.
3660
Georg Brandl3ee81df2008-05-17 18:14:43 +00003661- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003662 several extension methods and modules do not work without unicode
3663 support.
3664
Georg Brandl26543b12008-01-21 18:36:51 +00003665- Issue #1882: when compiling code from a string, encoding cookies in the
3666 second line of code were not always recognized correctly.
3667
Georg Brandl14404b62008-01-19 19:27:05 +00003668- Issue #1679: "0x" was taken as a valid integer literal.
3669
Georg Brandl6caad7d2008-01-26 14:19:22 +00003670- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003671 added.
3672
Christian Heimesc94e2b52008-01-14 04:13:37 +00003673- sys.float_info / PyFloat_GetInfo: The floating point information
3674 object was converted from a dict to a specialized structseq object.
3675
Georg Brandl3ee81df2008-05-17 18:14:43 +00003676- Patch #1816: Added sys.flags structseq. It exposes the status of
3677 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003678
Georg Brandl3ee81df2008-05-17 18:14:43 +00003679- Objects/structseq.c: Implemented new structseq representation. The
3680 patch makes structseqs (e.g. the return value of os.stat) more
3681 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003682
Georg Brandl3ee81df2008-05-17 18:14:43 +00003683- Patch #1700288: added a type attribute cache that caches method
3684 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003685
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003686- Bug #1776: __import__() no longer accepts filenames on any platform.
3687 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003688
Georg Brandlaed6c662008-01-07 17:25:53 +00003689- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3690
Georg Brandl3ee81df2008-05-17 18:14:43 +00003691- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3692 envvar and sys.dont_write_bytecode attribute. All these can be set
3693 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003694
Georg Brandl3ee81df2008-05-17 18:14:43 +00003695- Improve some exception messages when Windows fails to load an
3696 extension module. Now we get for example '%1 is not a valid Win32
3697 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003698
Georg Brandl3ee81df2008-05-17 18:14:43 +00003699- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003701- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3702 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003703
Christian Heimes0a8143f2007-12-18 23:22:54 +00003704- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003705 and INF. float("nan"), float("inf") and float("-inf") now work on
3706 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003707
Georg Brandl3ee81df2008-05-17 18:14:43 +00003708- Compiler now generates simpler and faster code for dictionary
3709 literals. The oparg for BUILD_MAP now indicates an estimated
3710 dictionary size. There is a new opcode, STORE_MAP, for adding
3711 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003712
Georg Brandl3ee81df2008-05-17 18:14:43 +00003713- Issue #1638: %zd configure test fails on Linux.

3729 running, and if the deallocation of its frames somehow calls the
3730 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003731

3736
Georg Brandl3ee81df2008-05-17 18:14:43 +00003737- Issue #1460: The utf-7 incremental decoder did not accept truncated
3738 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003739
Georg Brandl3ee81df2008-05-17 18:14:43 +00003740- Patch #1739468: Directories and zipfiles containing a __main__.py
3741 file can now be directly executed by passing their name to the
3742 interpreter. The directory/zipfile is automatically inserted as the
3743 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003744
Georg Brandl3ee81df2008-05-17 18:14:43 +00003745- Issue #1265: Fix a problem with sys.settrace, if the tracing
3746 function uses a generator expression when at the same time the
3747 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003748
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003749- sets and frozensets now have an isdisjoint() method.
3750
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003751- optimize the performance of builtin.sum().
3752
Neal Norwitz44f326e2007-10-05 05:29:17 +00003753- Fix warnings found by the new version of the Coverity checker.
3754
Georg Brandl3ee81df2008-05-17 18:14:43 +00003755- The enumerate() builtin function is no longer bounded to sequences
3756 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3757 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003758
Georg Brandl3ee81df2008-05-17 18:14:43 +00003759- Issue #1686386: Tuple's tp_repr did not take into account the
3760 possibility of having a self-referential tuple, which is possible
3761 from C code. Nor did object's tp_str consider that a type's tp_str
3762 could do something that could lead to an inifinite recursion.
3763 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3764 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003765
Georg Brandl3ee81df2008-05-17 18:14:43 +00003766- Issue #1164: It was possible to trigger deadlock when using the
3767 'print' statement to write to a file since the GIL was not released
3768 as needed. Now PyObject_Print() does the right thing along with
3769 various tp_print implementations of the built-in types and those in
3770 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003771
Georg Brandl3ee81df2008-05-17 18:14:43 +00003772- Issue #1147: Exceptions were directly allowing string exceptions in
3773 their throw() method even though string exceptions no longer
3774 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003775
Georg Brandl3ee81df2008-05-17 18:14:43 +00003776- Issue #1096: Prevent a segfault from getting the repr of a very
3777 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003778
Brett Cannon1e534b52007-09-07 04:18:30 +00003779- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003780 PyObject_Call() never calling back out to Python code to trigger
3781 recursion depth updates/checks. Required the creation of a static
3782 RuntimeError instance in case normalizing an exception put the
3783 recursion check value past its limit. Fixes crashers
3784 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003785
Georg Brandl3ee81df2008-05-17 18:14:43 +00003786- Patch #1031213: Decode source line in SyntaxErrors back to its

3790 with %G.
3791
Georg Brandl3ee81df2008-05-17 18:14:43 +00003792- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00003799- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003800 __*__ attributes. (Some already existed, e.g., __doc__ and
3801 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003802
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003803- Add -3 option to the interpreter to warn about features that are
3804 deprecated and will be changed/removed in Python 3.0.
3805
Georg Brandl2134e752007-05-21 20:34:16 +00003806- Patch #1686487: you can now pass any mapping after '**' in function
3807 calls.
3808
Collin Winter62903052007-05-18 23:11:24 +00003809- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003810 "except E as target:". This is to provide forwards compatibility
3811 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003812
Brett Cannon229cee22007-05-05 01:34:02 +00003813- Deprecate BaseException.message as per PEP 352.
3814
Georg Brandl3ee81df2008-05-17 18:14:43 +00003815- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003816 inherited from a builtin base.
3817
Vinay Sajip8549ce32007-05-06 17:53:37 +00003818- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003819 setting a plain string, ie don't expand to single letter identifiers.
3820
Raymond Hettinger13936692007-04-11 18:40:58 +00003821- Request #1191699: Slices can now be pickled.
3822
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003823- Request #1193128: str.translate() now allows a None argument for
3824 translations that only remove characters without re-mapping the
3825 remaining characters.
3826
Georg Brandl5cb76c12007-03-21 09:00:39 +00003827- Patch #1682205: a TypeError while unpacking an iterable is no longer
3828 masked by a generic one with the message "unpack non-sequence".
3829
Neal Norwitzaa754b72007-03-21 06:39:48 +00003830- Remove unused file Python/fmod.c.
3831
Guido van Rossum143b5642007-03-23 04:58:42 +00003832- Bug #1683368: The object.__init__() and object.__new__() methods are
3833 now stricter in rejecting excess arguments. The only time when
3834 either allows excess arguments is when it is not overridden and the
3835 other one is. For backwards compatibility, when both are
3836 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003837 warning later). Also, type.__init__() insists on the same signature
3838 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003839
Georg Brandl3ee81df2008-05-17 18:14:43 +00003840- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3841 object to complex using its __complex__() method before falling back
3842 to the __float__() method. Therefore, the functions in the cmath
3843 module now can operate on objects that define a __complex__()
3844 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003845
Georg Brandl3ee81df2008-05-17 18:14:43 +00003846- Patch #1623563: allow __class__ assignment for classes with
3847 __slots__. The old and the new class are still required to have the
3848 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003849
Georg Brandl3ee81df2008-05-17 18:14:43 +00003850- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003853- Patch #1462488: Python no longer segfaults when
3854 ``object.__reduce_ex__()`` is called with an object that is faking
3855 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003856
Georg Brandl3ee81df2008-05-17 18:14:43 +00003857- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003860- Patch #1444529: the builtin compile() now accepts keyword arguments.
3861
Georg Brandl7b9c5552007-03-12 14:30:05 +00003862- Bug #1678647: write a newline after printing an exception in any
3863 case, even when converting the value to a string failed.
3864
Georg Brandl871f1bc2007-03-12 13:17:36 +00003865- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003866 its argument, if it exists. If not, it will work like before. This
3867 allows customizing the output of dir() in the presence of a
3868 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003869
Collin Winter276887b2007-03-12 16:11:39 +00003870- Patch #922167: Python no longer segfaults when faced with infinitely
3871 self-recursive reload() calls (as reported by bug #742342).
3872
Georg Brandl3ee81df2008-05-17 18:14:43 +00003873- Patch #1675981: remove unreachable code from ``type.__new__()``
3874 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003876- Patch #1491866: change the complex() constructor to allow
3877 parthensized forms. This means complex(repr(x)) now works instead of
3878 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003879
Georg Brandlaa2321b2007-03-07 00:40:28 +00003880- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003881 makes the filenames the warning module prints much more sensible
3882 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003883
Georg Brandl49aafc92007-03-07 00:34:46 +00003884- Variant of patch #697613: don't exit the interpreter on a SystemExit
3885 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003886 variable is given, but break into the interactive interpreter just
3887 like on other exceptions or normal program exit.

Georg Brandlfb4b3b72007-04-24 15:27:13 +00004387- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
4388 (as opposed to the command line) will now write file names ending in
4389 ".cpp" too.
4390
Facundo Batistad918a652007-04-24 13:54:38 +00004391- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004392 the client's request was successfully received, understood, and
4393 accepted. Now in these cases no error is raised in urllib (issue
4394 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004395
Georg Brandl3ee81df2008-05-17 18:14:43 +00004396- Bug #1290505: time.strptime's internal cache of locale information

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004402- Added a timeout parameter to the constructor of other protocols
4403 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4404 work started with create_connection() and timeout in httplib, and
4405 closes patch #723312.
4406
Vinay Sajip8549ce32007-05-06 17:53:37 +00004407- Patch #1676823: Added create_connection() to socket.py, which may be
4408 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004409 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004410
Martin v. Löwis0af33882007-03-23 13:27:15 +00004411- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004418- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
4419 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00004420 directories.
4421

4431
Georg Brandlf66b6032007-03-14 08:27:52 +00004432- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004433 AttributeError instead of an IOError when the server's response
4434 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004435
Georg Brandl3ee81df2008-05-17 18:14:43 +00004436- Patch #957650: "%var%" environment variable references are now
4437 properly expanded in ntpath.expandvars(), also "~user" home
4438 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00004439
Georg Brandl3ee81df2008-05-17 18:14:43 +00004440- Patch #1429539: pdb now correctly initializes the __main__ module
4441 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004442 correctly now.
4443
Georg Brandlbad6f192007-03-13 21:32:56 +00004444- The nonobvious commands.getstatus() function is now deprecated.

4450
Georg Brandl3ee81df2008-05-17 18:14:43 +00004451- Patch #1530482: add pydoc.render_doc() which returns the
4452 documentation for a thing instead of paging it to stdout, which
4453 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004454
Georg Brandl3ee81df2008-05-17 18:14:43 +00004455- Patch #1533909: the timeit module now accepts callables in addition

4461 parameter which can be set to False to prevent the default
4462 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00004463
Georg Brandl9e6b4702007-03-13 18:15:41 +00004464- Patch #1581073: add a flag to textwrap that prevents the dropping of
4465 whitespace while wrapping.
4466
Georg Brandl92a6bae2007-03-13 17:43:32 +00004467- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004468 are set for invalid interpolation sequences that would lead to
4469 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004470

4483
Georg Brandl94fe3f52007-03-13 09:32:11 +00004484- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485 field names in its exception message if you try to write a record
4486 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004504

4512 returned string up to the first NUL character.

4523
Georg Brandl3ee81df2008-05-17 18:14:43 +00004524- unittest now verifies more of its assumptions. In particular,
4525 TestCase and TestSuite subclasses (not instances) are no longer
4526 accepted in TestSuite.addTest(). This should cause no
4527 incompatibility since it never made sense with ordinary subclasses
4528 -- the failure just occurred later, with a more cumbersome
4529 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00004530

4538 given a unicode argument and os.listdir() returns unicode filenames.
4539
Georg Brandl3ee81df2008-05-17 18:14:43 +00004540- Patch #1673619: setup.py identifies extension modules it doesn't
4541 know how to build and those it knows how to build but that fail to
4542 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004917- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004918 time so that opening a database previously created with the DB_DUP
4919 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4920 opens. Specifically: dictionary assignment to a DB object will
4921 replace all values for a given key when the database allows
4922 duplicate values. DB users should use DB.put(k, v) when they want
4923 to store duplicates; not DB[k] = v.

4930 characters with ASCII value less than 32. Also, it correctly quotes
4931 dots only if they occur on a single line, as opposed to the previous
4932 behavior of quoting dots if they are the second character of any
4933 line.
